3M Peltor LiteCom 57A3 Protective Earmuffs & Headband. The 3M Peltor LiteCom 57A3 earmuffs with headband is an excellent solution for hearing protection and communication in environments where noise is more intense. These high-performance earmuffs feature a built-in wireless system that allows users to communicate over short distances using speakerphone with other LiteCom headsets, as well as other wireless communication devices operating on the same frequency. The 8 channels and the 38 secondary channels provided allow users to communicate individually, ensuring ease and security in communication. The function of this earpiece makes conversation easy and instant, even in the noisiest environments, thanks to the built-in noise cancelling microphone that reduces unwanted audio interference. In addition, the earmuffs features an auxiliary input that allows connection of a mobile phone or other external wireless devices, regardless of the frequency, offering additional flexibility to users. It is available as headband, helmet-mounted and neckband, ensuring comfort and stability during use, suitable for professionals and workers who require safety and communication at the same time.

3M Peltor LiteCom User Manual
What is noise attenuation? The process of noise energy loss is called attenuation and it is the attenuation data that must be considered when selecting the appropriate ear protectors.
What is SNR? The SNR is a simplified description of hearing protector attenuation. The SNR value can be used to compare the level of noise attenuation offered by different hearing protectors. To determine the sound pressure in your ears, you subtract the SNR value from the average noise level measured. For example:
The noise level averages 99 dB.
Wear ear protectors with an SNR of 19.
So the sound pressure in your ears is on average 99 - 19 = 8th dB.
The higher the SNR, the higher the level of noise attenuation provided by the hearing protection.What is HML? A method of assessing hearing loss based on 3 parameters.
H = High
M = Medium
L = Low
The terms refer to the measure hearing of protector attenuation in high (H), medium (M) and low frequency dominated (L) noise.What are dBs (decibels)? Noise is measured in units of sound pressure levels called decibels (dB).
