How It Works
to the sophisticated, audiophile components extreme linear
characteristics, wide 80 dB dynamic range and surface mount technology,
Pro Ears provide the clearest, most natural sound quality ever found in
hearing products. Every sound comes in crisp and clear, so natural its
like you are wearing nothing at all, only better, as you hear low
decibel sounds you can not hear with the naked ear.
To truly protect ones hearing it is vital that the
hearing protection not only react quickly when high noise levels are
perceived, but also recover just as quickly once the noise level drops
to a safe level. We are proud to say Pro Ears Gold Series offer the
fastest 'Attack Time' in the industry at an unprecedented 1.5
milliseconds (the Pro Series attack time is 5.5 milliseconds). The
shorter the attack time the more natural the sound. Longer attack times
result in choppy or rising and lowering sound. These sound
imperfections can lead to missed communications, and after extended
wear, headaches as the brain struggles to adapt to uneven sounds levels.
increases the ability to hear clearly and at great distances. With the
advanced technology of Pro Ears you will have the adjustable range to
increase hearing up to 8 Times normal. For those who have a limited
range of hearing or for those, such as hunters, wildlife observers, law
enforcement officers, etc, the ability to hear distant sounds is vital.
In addition, Pro Ears offers the only programmable units that allow the
user to change gain sensitivity so you can adjust your Pro Ears model to
fit your specific needs.
Pro Ears offers complete electronics in each cup there is no need for
connecting wires that can snag on branches or increase power consumption
and reduce battery life. Due to this design the wearer also has
independent volume controls on each cup to compensate for disparate
hearing or for unique situations that call for one ear to be more or
less sensitive. And because each cup features it's own electronics every
Pro Ears provides true stereo for directional sound detection.
Comfort is a priority with Pro Ears and every model is
designed to be worn for long periods of time comfortably. It begins
with the adjustable, padded headband that is quickly adjusted to fit
your head. We use a special formula foam for your replaceable Sealing
Rings. These special Rings not only conform to the wearer but are soft
and pliable for wear with glasses. These also help alleviate bone
transmitted sound vibrations to further protect the wearer from loud
noise levels. The weight of the earmuffs will also impact comfort and
Pro-Ears are among the lightest in the industry. We design every part
of our hearing protectors to eliminate weight and increase comfort.
Even our battery was selected to minimize weight.
model Pro Ears features a modular, fold up design for easy carry and
convenient storage. Nothing aggravates more than to have batteries fail
so we use commonly found 'N' size 1 1/2 volt batteries that will provide
the industries longest, minimum 200 hours of use. Batteries are also
included with each new Pro Ears model.
Dual Layer, Printed Circuit Boards with extensive ground planes make
Pro Ears immune to interference caused by Radios, TV, Ham stations and
other sources. The All-Surface Mount Design uses the highest quality
parts available and is based on five, low power Integrated Circuits
allowing the unit to consume less than 4 Ma allowing for longer battery
life. No other electronic hearing protector can make these claims –
Pro Ears Gold Series feature Receiver/Input capabilities for:Apple

Scanners and other electronic Communication/Entertainment Receiving
Devices so you can listen to communications or relax with your own
music, educational material or on the job media.
only do Pro-Ears feature the most advanced, sophisticated electronics
in the industry, we have also proven ourselves in the Industrial arena.
When thoroughly evaluated by independent testing laboratories, Pro-Ears
Electronic Hearing Protection / Sound Amplification products excelled
and were Certified MSHA 2G-4108 and ANSI / UL 913 for Class I, II and
III, Div. 1, Group A, B, C and D Hazardous Locations. These prestigious
findings further prove the unmatched proficiency, reliability and
technological advances found only in Pro-Ears products. When the
environmental conditions require the ultimate in hearing protection as
well as the necessity to communicate, there is only one choice,
PRO EARS® Advanced Hearing Protection Technology
Dynamic Level Sound Compression™
Ears models of electronic hearing protection/amplification muffs
feature 'DLSC™' Dynamic Level Sound Compression Technology. This
superior technology allows the wearer to hear every sound even during
high volume noise spikes. While other brands say they have 'compression'
technology, they do not. What they do have is outdated technology,
either 'Peak Clipping' or 'Automatic Level Control'. 'Peak Clipping'
turns the amplification system off when noise levels reach a preset
decibel leaving the wearer with passive muffs. 'ALC' simply reacts to
high noise levels by lowering the unit's volume so the louder sounds
still drown out softer sounds. In both technologies loud noise levels
compromise the ability to hear quieter sounds. Only Ridgeline's 'DLSC'
technology protects hearing while at the same time allowing the wearer
to hear lower volume sounds such as normal conversation. 'DLSC' works by
instantly 'compressing' all noises over the 70 dB threshold by 50% to a
safe level while amplifying all sounds below that to 70 dB. The result
is the wearer will hear everything, including conversation, while
simultaneously being protected from dangerous, high volume sounds.
1 - Gain and Volume Control
This block amplifies the
microphone. The gain can be adjusted from 0 dB to 40 dB.
2 - High Pass Filters
Cuts the low frequencies below 300Hz,
eliminating most of the wind noise and other low frequencies.
3 - Dynamic Level Sound Compression (DLSC™)
automatically adjusts or compresses the input signal by as much as 45
dB. The DLSC will automatically adjust the internal gain in order to
maintain the safe output level of 85 dB.
Block 4 - Low
Limits the high frequencies that are allowed to
pass. The 3 dB point is at 5Khz.
Block 5 - Speaker Amp
stage provides the high output current required to drive the speaker
with no distortion.
