You know the situation: a friend of yours, who claims (or pretends!!!) to be an audiophile invites you to visit him and enjoy his listening room for an oustanding HiFi testing session. We, real audiophiles (aren't we all?) know pretty well that friends' systems will usually sound horrible. Until now we had just two escape plans:
You can also choose between two flavours: a clear one that delivers a medium level of protection and a red one for highly noisy environments and applications. In the chart below you can see how many dB's of attenuation, at different frequencies, are achievable with these two different models. Remember that an attenuation of 20 dB is very strong. At live rock concerts you might be exposed to sound pressures as high as 110/120 dB (peak), but with these ear pugs installed you'll still hear loud but at comfortable (and safe!) levels.
Moreover, attenuation varies slightly depending on frequency, this means that the sound you hear is more or less similar to the one you're listening to, just lower in level. Standard ear plugs, instead, deliver a muffled and confused sound, because they cut certain frequencies and let others pass.
If the guys at Ear Peace would be kind enough to send test samples (yes, pretty please, with sugar on top!) I'll be wearing them at the next HiFi Show I'm going to visit. Certain demo rooms are simply ear-splitting!
