Discriminative Frequency Training - 2/3 Octave Notches

Switch to : Full Octaves  (easier)

Purpose

Equalization (EQ) refers to the process of altering the frequency response of an audio system or a sound file. EQ can be used for esthetic reasons or to compensate for unwanted bumps or holes in the audio spectrum.

The following files will help you to discriminate missing frequencies across the audible range. By training your ears to recognize those missing frequency bands, you will acquire the ability to locate unwanted frequency dips by ear and find the correct EQ fix in one go.

Training Files

Listen to each file and associate the missing 2/3 octave band with the value of its center frequency.

             
40 Hz 63 Hz 100 Hz 160 Hz 250 Hz 400 Hz 630 Hz
             
1 kHz 1.6 kHz 2.5 kHz 4 kHz 6.3 kHz 10 kHz 16 kHz

Test Files

For each column, tick the appropriate radio button. When you have labeled all 10 files, click the "Submit" button to obtain your score. Reload the page as often as you want to perform new tests.

                     
 40 Hz  
 63 Hz  
 100 Hz  
 160 Hz  
 250 Hz  
 400 Hz  
 630 Hz  
 1 kHz  
 1.6 kHz  
 2.5 kHz  
 4 kHz  
 6.3 kHz  
 10 kHz  
 16 kHz  

Once you have succeeded in getting 9 or higher without listening to the individual labeled files during the test, your training will have been successfully completed.
