Overview: The Alpine PartyPlugs are a revolutionary new type of
earplug that filters out damaging sounds while providing a comfortable fit.
AlpineAcousticFilters: The high-quality acoustic filters in the
PartyPlug hearing protectors are designed to reduce the volume of music or other
noise to a safe level, while maintaining sound quality and allowing you to still
carry on a conversation. The PartyPlugs are barely visible due to the unique
AlpineThermoShape: PartyPlug hearing protectors are made of a special
AlpineThermoShape material that adapts to the shape of your ears so you always
have the perfect level of noise attenuation along with a comfortable fit. A good
fit eliminates any sense of isolation or external pressure on your ears, so you
can comfortably wear them for long periods of time. The PartyPlugs are available
in barely visible transparent as well as black, silver, and white.
Miniboxx: In addition to a standard storage case, the PartyPlug pack
also comes with a Miniboxx keychain carry-case that's small enough to also carry
it in your pocket.
Safe Volume Levels: The maximum statutory volume limit to which
hearing may be exposed is around 80 decibels (dB). Prolonged exposure to noise
levels above 80 dB can lead to hearing damage or even hearing loss. Official
reports show that that 80 dB level is commonly exceeded in our modern world.
Concerts are a good example, where volume levels can reach 120 dB. For rock
musicians, most of the harmful noise is mainly produced by the drums and the
amplifiers, whereas for classical musicians their own instruments and those
nearby, can greatly affect their hearing. The following chart shows the maximum
exposure time at various decibel levels above 80 dB:
|Noise Level ||Maximum exposure
without hearing protection |
|86 dB ||2 Hours |
|89 dB ||1 Hour |
|92 dB ||30 Minutes |
|94 dB ||15 Minutes |
|98 dB ||7 Minutes |
|102 dB ||3 Minutes |
|106 dB ||90 Seconds |
