Impact™ Sport sound amplification earmuffs
Thursday, May 15, 2008

Howard Leight has introduced a new ultraslim sound
amplification earmuff specifically designed for use in intermittent and
impact noise environments. Impact™ Sport sound amplification earmuffs
incorporate high-tech patented electronics that amplify ambient sounds up to
a safe 82 dBA, while at the same time providing NRR 22 protection against
hazardous noise. This allows wearers to stay connected with their
environment while their hearing is protected.
"Impact Sport provides users with the best of both worlds," said Renee
Bessette, COHC, Marketing Manager for Sperian Hearing Protection, LLC. "It
allows users to hear what's going on around them--including co-workers,
signals and alarms--while still providing needed protection from hazardous
noise. In fact, Impact Sport is ideal for those who are exposed to
intermittent or impact sounds, such as supervisors or visitors on tour of a
facility."
Designed for increased comfort during long-term wear, Impact Sport earmuffs
feature a padded leatherette headband that is easily adjustable for a
secure, non-slip fit. Ultraslim earcups eliminate the bulk of traditional
electronic earmuffs, enhancing comfort over the work day. A convenient
folding design allows easy storage in a pocket or in a belt storage case,
available separately. Snap-in ear cushions make replacement quick and easy
and also help extend the life of Impact Sport.
But the key to Impact Sport's success is in its patented ambient sound
amplification technology. For protection, Impact Sport actively "listens"
and automatically stops amplifying when ambient sound reaches 82 dB, well
under the OSHA 85 dBA Action Level. Sounds below that level are picked up by
built-in directional microphones and amplified up to a safe 82 dB, providing
more natural hearing and enhancing communication.
Impact Sport also utilizes Bilsom® Technology's patented Air Flow Control™
to further improve protection. A specially designed baseplate chamber and
high-tech non-woven layer manage the flow of air inside the earmuff to
control how sound reaches the ear. The result is better, more consistent
overall attenuation in virtually all noise environments.
Impact Sport includes an AUX input jack to allow connection to an external
MP3 player or other audio device. Internal electronics operate for up to 350
hours with two AAA batteries (included), and the unit automatically shuts
off after 4 hours.
