Human perception of sound is limited at very low frequencies, where most of the engine noise is. The soundproofing is more effective at higher frequencies.

WebThe music in a discotheque measures an average of 99 dB. You are wearing the Alpine PartyPlug with an SNR of 19. Thus, the acoustic pressure on your ears is on average 99 – 19 = 80 dB. The higher the SNR, the higher the level of noise attenuation provided by the earplugs. Bear in mind that the SNR value is a rough average.
