and Test Tones
2015.01.21'3:29 - Referral Page : The Neil Young sample is not the best to show 8 vs 16 bits difference. The difference is very easy to hear with high dynamic jazz music, but very hard to hear with distorted rock guitar.
2015.01.17'13:02 - Referral Page :
It helped me determine how good my Panasonic
RP-HTX7 headphones are really good, i think it can be another reccomendation as i got mine for 2 dollars, closed, with no rattling
2015.01.15'13:55 - Referral Page : Thanks for these tests. I actually did this only after buying a new headphones, the Sennheiser HD-280. I've noticed that they play very well at all frequencies. What I did notice tho, is that my left ear isn't quite as sharp as my right one...but now I know that, too! Thanks again! :)
2015.01.13'8:57 - Referral Page : Both of the sample files I downloaded have the exact same file size and wave form in Foobar. Isn't the 16bit supposed to be a bigger file?
2015.01.05'3:16 - Referral Page : You should make The Test be BEFORE the "answer key"... I clicked the audio links in the "files being tested" section too fast in a row and Firefox crashed. Otherwise nice test.
2015.01.04'6:21 - Referral Page : Great resource for musical earplug reviews! Please review the Etymotic "Ety Plugs"
2015.01.01'12:14 - Referral Page : Thanks a lot. Here is a small typo in "Personal Recommendation(s)" section: "They will also offer you the geatest", it should be "gReatest" indeed.
2014.12.16'12:56 - Referral Page : Not all of your tones are available as .wav files. That sucks
2014.11.18'22:57 - Referral Page : Awesome stuff! The Binaural test freaked me out
2014.11.13'11:36 - Referral Page : ur gay haha
2014.10.30'11:50 - Referral Page : I stopped the test because you can see the testfile on the bottom of firefox, that is played. Besides that my correct hits so far were about the percentage of pure guessing
2014.10.27'1:34 - Referral Page : Right before the voice calls out 100, the frequency spreads to the opposite side (from either channel). how do i fix that?
2014.10.27'1:31 - Referral Page : You are the best audio guy i've ever seen, just wanted to say that. :) Keep updating your page..
2014.10.16'18:45 - Referral Page : The link preview shows what sound I'm playing, this probably influences results unconsciously.
2014.10.11'8:06 - Referral Page : more binaural samples :)
2014.10.06'21:35 - Referral Page : Binaural test made me jumped out from my chair.... its amazing... superb quality... Wonderful job!!
2014.10.06'16:05 - Referral Page : It'd be nice to see which notes you got correct, as opposed to just a number.
2014.09.08'18:21 - Referral Page : Hallo, I'm an amateur sax player with a tinnitus ans am looking for hearing protection that is basically a low pass. Any recommendation you can give me? Thanks, Jan
2014.08.27'14:42 - Referral Page : Couldnt really hear any sonic differencies in these files 8bit vs 16bit. I managed to get full score though by focusing on clicks and pops (probably some nasty overs). My first request is fix the audio files to be pop and click free. My second suggestion is... Change the audio to Rockin in the free world by Neil Pono Young. Wouldnt that be hilarious?
2014.08.03'4:47 - Referral Page : Hi, Could you please publish app with test sounds to android? If you want I can work on that... These are really handy to test headphones on the go..
2014.07.26'5:36 - Referral Page : These test files helped me set up my Beomaster 5000 which had unlabeled speaker wires and proprietary connections. Now the speakers are in-phase and working perfectly!
2014.07.19'19:10 - Referral Page : Thanks for the useful web site. Very good!
2014.06.26'2:06 - Referral Page : When you hover over the Play buttons on the test the link preview tells you what note it will play. You should rename the files to "Note 1", "Note 2", etc. or change the HTML so that the link preview shows something else.
2014.06.24'20:56 - Referral Page : Just got the Audio technica ATH-M20x's for 50 bucks. Love em.
2014.06.24'20:50 - Referral Page :
To Stéphane Pigeon, founder of AudioCheck.net:
Why is the 'audio engineer' always referred to as a male throughout your website and articles? People of the audio industry would cite your work for scholarly papers and wouldn't mind just giving you and your writing a chance had you properly referred the audio engineer as a 'he or she'. I'm male by the way. What a shame to see this.
2014.06.16'6:17 - Referral Page : The 16 bit and 8 bit test is hoax. I downloaded your two files by right clicking and saving it. The file sizes are the same which means that they both are identical. Please Don't try to mislead people.
2014.06.13'22:36 - Referral Page :
I know, I can distinct 16 bit from 8 only in some rare circumstances, though, it is very loud music you have chosen to test. Maybe you would like to add a few other music and\or sound samples? Thank you!
2014.06.10'22:14 - Referral Page :
I really don't get any of this, starting with the hand-rubbing business.
2014.05.27'14:51 - Referral Page :
Hello! Your website is incredibly fascinating and helpful, but I need clarification on one point...
The sawtooth page states that a saw tooth is made of a fundamental sine wave (eg 100hz) and then all the harmonics to infinity . It then states a list of odd numbered harmonics (300Hz, 500Hz, 700Hz, ...).
It seems like an error because the Square wave is comprised of a fundamental and then odd numbered harmonics, and is stated in pretty much the same way on the Square wave page..
2014.05.17'10:20 - Referral Page : Thank you very much for this site! It helped me compare my FT 990 Pro vs my old Logitech G930 ... and test my ears as well (as far that's possible with those headphones. Fun fact: my tinitus went away for some time after hearing certain frequencies... Cheers form Germany. //Christoph
2014.04.19'5:03 - Referral Page :
I've just stumbled onto this fantastic website. As a physics student and musician, all this information is fascinating to me and it is so nice to have it all in one place. I have enjoyed testing my hearing and speakers. Thank you so much for making this great resource available.
2014.04.16'22:46 - Referral Page : Having toyed a bit with making speaker cabinets, man I wish I had this stuff back in the 80's Thieles equations are not enough. Sometimes you need to "hear" it. I did find out that I had an okay sound card however. Good tools to have...
2014.04.05'16:39 - Referral Page :
2014.03.31'1:45 - Referral Page : FEEL THAT BASS. It feels like a massage as its playing on my back
2014.03.30'16:38 - Referral Page : some of the test only do one side of the headphone is that correct? xD
2014.03.27'20:21 - Referral Page : Now available in the North America from Twisted Throttle here: http://www.twistedthrottle.com/brand/nonoise/
2014.03.13'13:13 - Referral Page : love the blind test, but i feel there needs to be at least 2 or 3 different styles of music represented. Highly compressed pop music is not the best way to test this. I would select a classical piece, and maybe a jazz or folk song that has more sparse instrumentation.
2014.03.12'18:45 - Referral Page : Hello, could you make something similar to 'virtual barber shop' on YouTube? I'd love to see what you guys come up with! Toby.
2014.03.07'19:37 - Referral Page : I love this page, but it bothers me that people can view the page source and look at the audio file names to cheat. Anyway you could rename them to hide what they are? Instead of gangnam8.wav and gangnam16.wav, how about calling them gangnamA.wav and gangnamB.wav?
2014.03.06'20:59 - Referral Page : It seems the "15-minute white noise track" file is misarranged. It's actually a pink noise. Please check.
2014.03.05'22:09 - Referral Page : Absolutely a wonderful site you have created! From the content to the layout, it is great. You have helped me confirm a diagnose of my faulty tweeter. Donation page? Thanks!
2014.02.14'9:09 - Referral Page : Thanks for the awesome site. I really enjoyed the ABX tests. My older ears aren't too bad!
2014.02.11'14:45 - Referral Page : Audiocheck is a great site for education and test. For perceptive audio system testing at home I have allways missed the following: A grey-noise generator with 1/3 octave selectable filters. Default is all filters active = Silence. Press 1 KHz band and e.g. 160 Hz band alternately to compare percieved level. Make a note and continue with other bands, still comparing with 1 KHz band alternately. Such test/generator will provide much better judgement of in-room audio system response than swept sine waves, due to distribution of discrete tones and standing waves. We can call it the Rasmussen test :-). But long ago CBS made a record: "7 steps to better listening"... they knew what they were doing, too bad Sony quenched them.
2014.02.08'19:51 - Referral Page :
Love to tease my cat with high pitched sounds
2014.02.05'15:46 - Referral Page : I can hear 10hz perfectly clear. Is that normal or do i have really good hearing?
2014.02.05'15:41 - Referral Page : Hi umm my head phones can play this and i can hear 16hz tones... im not joking.
2014.01.28'21:15 - Referral Page : Excellent site. I will be using these files with my students in a project class on the future of HD audio
2014.01.23'14:45 - Referral Page : 10/10... but you might like to fix the way the preview of the filename appears in the bottom line of browsers. I didn't even have to listen to score correctly.
2014.01.22'7:43 - Referral Page : many frequencies of your sound files are missing - it would be handy to be able to access 1.5k, 3k, 5k, 6k, 7k (1.5 and 3k were used in my last audiometric test and 8k I just can't hear at all, I'd like to test my limit between 4k and 8k tones)
2014.01.22'7:38 - Referral Page : I can't hear any of the mosquito sounds. I need a visual indicator of when the sound stops and starts. The colours of the arrow/squares changes, but which colours is start and stop?
2014.01.05'17:25 - Referral Page : I was a little thrown off by this test because the pitch names are wrong... ex. you have C3 labeled on C2. They are all of by an octave.
2013.12.31'22:39 - Referral Page : Excellent binaural test, I thought someone was knocking on my door!
2013.12.19'22:04 - Referral Page : It's not a test of perfect pitch BECAUSE you've already said it's the C scale. I can get 10/10 because I can find where the semitones are between E-F and B-C. If you didn't cut out the black notes, I'd probably get zero.
2013.12.17'1:14 - Referral Page : I could hear 20HZ
2013.12.12'18:19 - Referral Page : That binaural test scared me like HELL!!!!!!!!! It was so realistic that I jumped off the chair. (I tested it at 8 PM... and I live on the 4th floor... just think about how horror it is on a time like that). I didn't know what would the test sound like.
2013.12.09'8:27 - Referral Page : Excellent :)
2013.12.08'14:41 - Referral Page : Hello, I do agree that it is strictly impossible to detect the abolute phase of a recording by single listening. BUT when listening to the same recording one pass with absolute phase "up" and the next with absolute phase "down" it becomes very obvious that one of the two is playing right and the other one is more on the dark side. but don't try with random A/B, you will be confused after 3 play... We are talking of phase coherent recording, indeed, no pan-mixing! best regards
2013.11.29'19:32 - Referral Page : Thank you
2013.11.24'17:36 - Referral Page : This is a JOKE. A bad joke. You need to take this site DOWN. It is irresponsible for people to think they can test their hearing online. I trained and worked as a recording engineer and I've also informally studied human perception and by any measure, this site is irresponsible.
2013.11.24'15:01 - Referral Page : An excellent site for testing audio equipment. Nice work!
2013.11.22'4:11 - Referral Page : Please add a challenge to tell a high quality 320 kbit mp3 compared to a 24 bit 44.1/96 khz wav. From my experience it is impossible to discern the difference in ABX tests, but lots of people think they can.
2013.11.21'12:22 - Referral Page : LOL
2013.11.21'10:30 - Referral Page :
I was just truly amazed by the headphones binaural test. I seriously thought someone was knocking on my door :) really!
2013.11.14'6:20 - Referral Page : quick comment: I've worked with DAC's and ADC's at the chip level, and performed the exact same tests you show in your video. Your assertion that digitized signals are not stairsteps totally perplexed me--because I have seen the stairsteps at the output of my DAC's with my own eyes. You really should mention the bandwidth limiting output filter earlier in the video.
2013.11.13'13:50 - Referral Page : Very nice site, I'm particulary interested in the "Earplug reviews" page. The idea of listenning to the effect of an hearing protector is great. Thank you
2013.11.10'19:01 - Referral Page : If you hover over the play button, you can see the bit in the file name.
2013.11.08'20:08 - Referral Page : Useful and easy! I suggest not using the word "flat" to mean "unchanging" -- I was confused at first (because of the musical context). Thanks!
2013.11.08'17:12 - Referral Page : This is pretty cool
2013.11.06'14:57 - Referral Page : well bass shaker test .. some ppl test it while headphones is connected to amp or avr .. at high volume it rattled my new x1 fidelio right speaker .. and on my friends x1 the left speaker rattled also at high volume .. so what is your opinion ?? i also tried a grado s80i and rattled but at a higher volume .. i think you should put a limit or caution as all these headphones tried are new .. or it means these headphones are bad quality ? heavy bass mp3 plays at max volume with no rattle
2013.11.05'9:37 - Referral Page : audiocheck.net's square wave looks exactly like wavtones.com's. Since I cannot download sawtooth und triangle tones from wavtones.com for free, I wanted to ask if those test tones on audiocheck.net are exactly the same as on wavtones.com?
2013.11.02'6:54 - Referral Page : Your test for audible frequency changes, 3dB, is showing the wrong score. It's painfully obvious which is which but your test isn't registering answers correctly.
2013.10.30'2:47 - Referral Page : The samples in the blind test are a bit short. Although they're obviously intended to catch perceived differences that are quite obvious, after adjusting to their sudden start, you barely have chance to listen. Also, it'd be better if these files were PCM rather than MP3. (The relative effects of the encoding might give clues as to which is which, regardless the quality of encoding.)
2013.10.21'2:25 - Referral Page : I passed all the way to 20 kHz in about 7 minutes. I was clearly able to hear the difference up to 17 kHz (10/10 each time). Afterwards, I was able to cheat by timing the delay before each audio clip would play. While the unfiltered clips start immediately, the filtered clips have a short delay. Please fix this bug!
2013.10.18'18:56 - Referral Page : Beautiful page - it tests most of the aspects of my earphone :) Thanks
2013.10.17'21:51 - Referral Page : The file names of the sound files reveals if the sound level is increased, decreased or flat. Every time I click on a play-button, this file name is shown to me by the browser. This would be a better blind test if such revealing file names were not used.
2013.10.06'15:06 - Referral Page : Awesome, thx for building it. i now can show my headphones can sound better.
2013.10.03'6:17 - Referral Page :
Please include tests for left/right ear. Like ability to hear which side is louder, and which side have higher pitch.
Also ability to log in, and save and share results would be cool. And see others people saved results, so you can show actually histogram, and how good somebody is. Options like age, sex and audio expirience could be filled in to. Thanks.
2013.10.03'2:55 - Referral Page : Cool
2013.10.03'0:07 - Referral Page :
Very nice site, i thought
and asked my doctor that only babies can hear as low as 20Hz, I was wrong,or this audio interface ain't very accurate, which is quite good possible with the very low frequencies.
2013.10.01'5:13 - Referral Page : It is normal to experience ringing in the ears from this test?
2013.09.19'21:56 - Referral Page : you should give some known headphones examples so people are able to compare the results
2013.09.13'10:59 - Referral Page : Brilliant! Been looking for ages for a page like this. Thanks!
2013.09.11'6:34 - Referral Page : Was totally blown away by the binaural test.
2013.08.30'23:45 - Referral Page : I am looking for a pair of in-ear binaural mics, and I was really impressed with the quality of your binaural test. Which equipment did you use?
2013.08.19'4:26 - Referral Page : using Gangnam Style with all its digital sound doesn't make any sense for testing 8-bit versus 16-bit. You should use real analog instruments such as a piano or violin.
2013.08.13'12:44 - Referral Page : I used the sine tone gen. for a few frequencies. I went up to 19-20kHz, than I found out, that either my ears suck, or the speakers are garbage, since I could not hear anything above 19kHz. Is it possible your generator sucks rather than my ears?
2013.07.31'9:09 - Referral Page :
can you make it a bit clearer?
2013.07.16'22:07 - Referral Page : Nice site!
2013.06.01'3:07 - Referral Page : one driver at a time full range sweep
2013.05.30'19:16 - Referral Page : The link at the bottom points to the Pink Noise instead, but when I changed the URL manually, I was able to download the Brown Noise ;)
2013.05.29'18:41 - Referral Page : Hi there, wonderful site. Was wondering if you knew where I could get a set of speakers that I am thinking of branding tested here in the states. Thanks
2013.05.27'21:44 - Referral Page : First of all great website! It's really helped me learn to the subtle differences between frequencies and I would definitely donate $ if there was an option to do so. A way this site could be improved in my opinion is if there was another set of freq boosts/notches tests that went by the instrument instead of the whole mix. Ie "which instrument is boosted at what freq by 6 db" or something like that. Obviously you guys would know a better way to go about it but that would be very helpful!
2013.05.15'10:40 - Referral Page :
Very nice ! Thank you Sir!
2013.05.13'2:37 - Referral Page :
My hearing cuts off pretty dramatically at 8k. i did the Hi frequency test with the threshold set to 12k and passed. But I believe I did this mainly by sensing a boost in volume at the low frequencies. So I'm guessing that the total power is held constant? Or is it an illusion on my part?
I didn't mean to suggest there was a slope. If I take the full spectrum and create a new signal by cutting off all above 12 k, but keep total power the same, then everything below 12 k rises equally. true? Is that happening?
2013.05.05'1:58 - Referral Page : My name is Norberto Amaral and I have been invited to give a talk in TEDxLuanda in Luanda, Angola. I would like to use two sound files I got from this website (...) in my presentation and kindly request your permission to do so. This is a non-commercial event and I am NOT earning any money, nor anyone in the event's organization. Thank you for your time, Norberto
2013.05.04'13:05 - Referral Page : Have you thought about making these tests available as an iOS app? Or is there a test app that you would recommend?
2013.04.30'17:58 - Referral Page : Great page - cleared some of the stuff up with my system!
2013.04.26'15:36 - Referral Page :
with reference to the table on this page surely the top row represents the 8th harmonic of the bottom row etc The bottom row being the fundamental or 1st harmonic the next row up is the 2nd harmonic, the next row the 4th harmonic, finally the 8th harmonic at 8 times the fundamental frequency. other harmonics will occur at 30, 50, 60, 70, Hz etc.
2nd Harmonic can also be known as 1st overtone.
2013.04.25'16:27 - Referral Page : What about front right, front left, and back right, back left?
2013.04.22'0:27 - Referral Page : i can't hear my webpages
2013.04.06'4:09 - Referral Page :
in reference to masking effect idea on 2013.02.11, see this graph
2013.03.31'23:06 - Referral Page : These square/triangle/sawtooth generators have bad aliasing. Generate a square/saw/triangle wave at 15 kHz or so, and you can clearly hear all the aliased harmonics. You can see them on the spectrum too at -40 dBFS or so. Creating the waves through additive synthesis of sine waves up to fs/2 is the easiest way to avoid this. https://gist.github.com/endolith/407991
2013.03.26'10:34 - Referral Page : Pre-compiled audio test CD's
2013.03.23'20:52 - Referral Page : Really cool test! I got 17Khz !!!!
2013.03.22'4:42 - Referral Page : This site rules. Thank you so much!!
2013.03.17'22:56 - Referral Page : Cool site, thanks. Never would have guessed that English is your second language, didn't notice anything that needed correcting - better than most native English speakers!
2013.03.13'0:11 - Referral Page : Can the Quality test that is the bass shaker damage my headphones? I played it at high volume and could see the drivers under a lot of stress. I had rattling a few times but these are brand new headphones. Thanks
2013.03.10'12:56 - Referral Page :
This is a great test. However to a newbie it took me far too long to understand how to use it. This was probably because I started on a page where I could not hear the difference between the two types. The page should explicitly state something similar to the following in my opinion to make it abundantly clear.
Listen to the reference files of full range and the low-pass filtered noise. If you can hear a difference try the test otherwise pick a lower frequency. For the test, each of the 10 files is either a full range or a low-pass filtered noise. Listen carefully and pick one. You can replay the reference files above as a comparison when making your choices.
2013.03.09'5:08 - Referral Page : its greAT
2013.03.06'14:39 - Referral Page : Timing Difference should be less than 0.5 ms. Find a sample at http://we.tl/IsCJwHJLn6.
2013.02.25'14:04 - Referral Page : Congratulations. Best online hearing test I have seen so far
2013.02.25'13:45 - Referral Page : Add test sounds for 4 channel stereo - 2 left, 2 right.
2013.02.16'10:44 - Referral Page : Great site, but unable to download Timing Difference and Low-Pass Filtering wav file under Stereo Perception and Sound Localization.
2013.02.11'7:12 - Referral Page : How about some examples of masking effects.. like start out with a 1.2k tone and say 3k tone at same level and then keep running the 1.2k tone up in level, etc. you could do it for serveral frequenceis and would be really cool. thank you for the great site. Tom J. .
2013.02.08'14:54 - Referral Page : The test sweep file is encoded in a 192kbps MP3 file which has a low pass filter as well as a shelving filter to remove unnecessary audio data. Depending on the encoder presets, frequencies from 17-22kHz can be severely attenuated or even inaudible which affects the integrity of this test. If the file was recorded in PCM audio or saved as a WAV file, you can use FLAC encoding which is lossless compression(perfect audio data, but smaller file size).
2013.02.07'22:41 - Referral Page : Can you add more notes to perfect pitch test? Like three groups: C scale, chromatic scale and expanded chromatic scale (more than 1 octave)
2013.02.06'15:11 - Referral Page : Just perfect, really. You are very professional and because it is easy to use your blind audio test, I learned how to answer correctly. I can answer 10/10 correctly now. Thanks.
2013.02.05'21:55 - Referral Page : I was doing your low frequency harmonic test, and I hear 10 hz. you say there is no way I hear it. Is it because of my earphones? Thanks.
2013.02.03'19:49 - Referral Page : At what playback level (in Db) is your grey noise calibrated at?
2013.01.21'23:15 - Referral Page : This site would be even nicer if you provided the wav files along some sort of hash like md5 to reduce chances of corruption.
2012.12.30'0:24 - Referral Page : I think the dynamic range test is broken. The first and second sounds are the same for both NdB and Mute, for all dB levels.
2012.12.29'22:38 - Referral Page : I scored 9 out of 10 in the frequency test at 10 k, but it's easy to tell because the filtered version is always louder. This is a bug in the test.
2012.12.27'22:20 - Referral Page : left & right test files are the same, please update
2012.12.20'17:46 - Referral Page : This was very interesting. I was able to quantify how bad my hearing is at higher frequencies. Fortunately it is fine between 250 and 1K. Thanks for this resource.
2012.12.19'15:51 - Referral Page : Nice website with fun tests
2012.12.12'21:26 - Referral Page : Would it be possible to release a tool that creates a sweep tone in CSV format?
2012.12.05'23:45 - Referral Page : A surround sound test: Left, Right, Centre, Side Left, Side Right, Back Left, Back Right and LFE channels.
2012.11.25'17:15 - Referral Page :
Could you test the Quies Confort foam earplugs? I believe the announced -35db nrr is really optimistic especially on low frequencies.
2012.11.02'7:41 - Referral Page : what program was used for mp3 compression (using Fraunhofer it seems)?
2012.10.20'4:27 - Referral Page :
How can i do linear combination of single tone signals in you website.
2012.10.19'2:32 - Referral Page : Outstanding Page and Tests... Thanks a Bunch DJTunes of California
2012.10.17'12:17 - Referral Page : Very nice!!
2012.10.15'14:35 - Referral Page : Haha, I only started hearing anything at 130Hz on my laptop speakers xD I heard the man's voice fairly clearly though. ( Was the sound not at the same volume as the man's voice..? Maybe this can be changed so people don't have to crank their speakers up possibly..? And every sound is the same volume? Or is that even possible? ) Hmm. And I'm fairly young too, 20..and my speakers are sonicmaster's by ASUS on my ASUS N53SV-A1. Just thought I'd give some feedback on this, thanks for reading. ^_^
