Peltor OPTIME Earmuffs (New 2005)
Peltor's OPTIME™ line of muffs incorporates all the acoustic engineering, wearer-focused comfort design and performance versatility that has made Peltor the leading name in earmuff protectors for over 50 years. Feature for feature, it's the best of the bests.

Multiposition designs are available in headband, neckband, helmet attachable and folding models to meet virtually every application need and wearer preference.

Liquid and foam filled cushions and broad, soft rings are the ultimate for a better seal (even with eyewear) and better comfort.

Padded wide headband with four-point steel suspension band cushions head while suspension distributes pressure for extra comfort and fits most facial profiles. Stainless steel construction resists bending and warping

Earcup pivot points allow wearers to tilt and adjust earcups for optimum comfort and efficiency.

Color-Coding allows compliance sighting. The colors of the OPTIME muffs allow supervisors to see from a distance if the correct muff is being used in an area.

Choosing the right earmuff for workers is a critical decision. A muff with too little attenuation leaves workers open to hearing dangers. One with too high of a protection level can "overprotect" and make it difficult to hear voices, signals and make a worker feel isolated...a common reason cited for non-compliance.

Now there's an easy solution:

Just Match the Numbers to the Noise Levels

The OPTIME line is devided by protection levels 95, 98, 101 and 105 dBA. All you have to do is match the OPTIME number to the assessed noise level of an individual's work area. For example, if an area's noise level can reach up to (without exceeding) 98 dBA, the right muff for a worker would be the OPTIME 98.
These replace the H10, H9, H7 and H6 series with a unified selection system, the OPTIME
See below the current listings for this new system.

Note: the attenuation data has not changed with the new system; the difference being in the appearance of the muffs to make it easier to detect compliance.

H10 Extreme Performance Earmuffs

New H10A HI-VIZ earmuff. Same specs as regular H10A
Model H10A HV
H10-A
with headband. NRR = 30 dB		 H10-B
earmuff behind the head. NRR = 29 dB		 H10-P3
hardhat attachable. NRR = 27 dB
The H10 series represents the ultimate in earmuff technology by providing one of the highest protection levels in the industry coupled with Peltor's extensive list of performance and comfort features. These muffs are the best of the best.

H7 Series Deluxe Earmuffs

for hardhats. NRR = 24 dB		 H7-B
behind the head. NRR = 26 dB
With a wide range protection that covers both severe and high noise levels, the H7 earmuffs are versatile enough to meet the protection requirements of almost any working environment.

H9 Series Select Performance Earmuffs
H9-A
with headband. NRR = 25 dB		 H9-P3
for hardhats. NRR = 23 dB
These universal hearing protectors are lightweight, comfortable and effective enough to meet most workplace requirements and one of the most popular earmuff choices in industry today.

H6 Series Low Profile Earmuffs
H6-B
behind the head. NRR = 26 dB		 H6-A
with headband. NRR = 21 dB		 H6-P3
for hardhats. NRR = 21 dB		 H6-F
folding earmuff. NRR = 21 dB

Peltor OPTIME Earmuffs
OPTIME 95

H6A/V
H6B/V

H6F/V
H6P3E/V
For Loud Noise Levels Up To 95 dBA
The lightweight OPTIME 95 muff features very low profile ear cups that fit well with most helmets, eyewear and other safety equipment. It is a comfortable choice that can provide effective protection especially against high frequency noise associated with many work areas and functions including machine shops and power tools.
For attenuation data, see the top of this page.
OPTIME 98

H9A
H9P3E
For Louder Noise Levels Up To 98 dBA
The OPTIME 98 is one of the most versatile earmuffs in industry today as it delivers the proper protection needed for a broad range of work areas with increased noise levels. When assessed noise levels reach up to 98 dBA, there is no better choice than the OPTIME 98.
For attenuation data, see the top of this page.
OPTIME 101

H7A
H7B

H7P3E
For Loudest Noise Levels Up To 101 dBA
It's imperative that workers in environments with the loudest noise have the correct level of protection as even minimal exposure can result in serious hearing damage. The OPTIME 101 is the right choice for these applications since it "muffles" and attenuates noise to a safe level so individuals can function long term with less danger.
For attenuation data, see the top of this page.
OPTIME 105

H10A
H10B

H10P3E
For Extreme Levels Up To 105 dBA
Developed for the ultimate protection in the most demanding noise environments. The OPTIME 105 features added mass and volume, plus a unique "double-shell" earcup design (two cups connected via a foam inner layer to reduce structural resonances) to provide the maximum in noise reduction throughout the full range of low and high frequencies.
For attenuation data, see the top of this page.
