INVISIBLE EARPLUGS?
Choose the "Canal-Only" Style and beige color for the closest you can get
to an invisible earplug. We have developed this option for everyone who
loves to go to clubs and concerts, but who wants a natural sound hearing
protector they can wear without attracting unwanted attention: "Dude! I
didn't know you had a hearing aid!?" |
The unique Alpine Tuned Acoustic Filter System provides hearing protection that is
tuned to your specific application through selection of one of five
different filters. By closely following the frequency
response of the human ear, Alpine noise filters turn down the volume of the noise
you hear, without distorting the quality of the sound you hear. That means you will
be able to hear the sounds you need to hear, accurately and comfortably, while
still getting the protection you need from dangerous or disturbing environmental noises.
We also offer our Perfect-FitTM Model ER Custom Natural Sound
Earplugs which feature the Etymotic Research acoustic filters, the most popular
natural sound solution in the US. The Model ER offers a little more accuracy in
sound than does the Model AF, however you may find the benefits of our Model AF
outweigh the slightly higher sound accuracy of the Model ER.
Model ER plugs come with two drawbacks:
(1) the filters used are large and cannot be hidden in the
ear, and (2) the filters used are available only in three variations. The
Model AF addresses both of these problems: (1) Alpine's Tuned Acoustic Filters are tiny, so they can be
installed in even the smallest canals for the least conspicuous solution
possible, and (2) Alpine's Tuned Acoustic Filters are available in five different attenuation levels for the greatest
flexibility, so you can choose a solution that accurately fits your unique hearing protection needs.
Please note: our top recommendation for professional musicians is the Model ER.
For all other applications, we believe both models offer excellent solutions.
Alpine Tuned Acoustic Filters are installed in your Perfect-FitTM
Model AF Custom Natural Sound Earplugs by a professional lab technician. Alpine Tuned Acoustic Filters are then interchangeable; one set of filters may
subsequently be changed out for a different set of filters
at any point. You can change the filters out yourself, or you can have the
filters changed and cleaned professionally, if you prefer to use our service.
