and Test Tones
Average price : about $5 a 10-pair box.
Mack's foam earplugs come in various models, offering more or less the same attenuation characteristics with subtle differences, as summarized below.
|Original||Teal||29||The original design, as reviewed here.|
|Ultra||Skin||32||Marginally stronger attenuation, stealth skin color.|
|Ear Ammo||Orange||29||Higher visibility. Odd bullet shape.|
|Slim Fit||Purple||29||Fits smaller ear canals or sensitive ears.|
|Snore Blockers||Green||32||Hollow design to minimize self-noise during sleep.|
|Dreamgirl||Pink||30||Fits smaller ear canals. Hollow design to minimize self-noise during sleep.|
|Sound Alseep||Blue||32||Same as the Snore Blockers, but different in color (!)|
NRR stands for Noise Reduction Rating. It is a standardized measure expressed in decibels (dB), and represents the overall attenuation offered by the earplug. The higher the NRR, the stronger the attenuation. Differences in the NRR of less than 3 dB between earplugs have no importance in practice.
ΔF represents an important factor for musical applications, as it measures the standard deviation from a spectrally flat attenuation between 60Hz and 16kHz. The smaller the ΔF, the higher the fidelity. ±3dB is virtually inaudible and can be considered as the very best one can get.
|At Home||•••||Great all-around earplug.|
|On the go||•••||Just as great.|
|Industry||•••||Excellent performer but requires clean hands to roll.|
|Music||•||Attenuation is too strong.|
Alternative: the non-tapered E.A.R Classic may better fit larger ear canals.
