3M™ Peltor™ PTL™ Earmuffs, H7A-PTL, help provide hearing protection, yet allow temporary listening to outside voices and sounds without removing the headset. An earcup button with a Push to Listen (PTL) mode eliminates the practice of “lifting off” the headset when talking with or listening to another person. Simply press the earcup button to provide a 30-second boost in the volume of conversation and other sounds. Workers needing to talk over details of a job or receive instructions can keep the hearing protectors on. An auto-switch returns earmuffs to normal hearing protection mode after 30 seconds. The wide and liquid/foam filled earmuff cushions fit gently to help create a comfortable, noise-blocking seal. These hearing protectors are commonly worn in the following industries: agriculture, airport workers, construction, heavy equipment operators, manufacturing, petroleum refineries, and racing.
This safety equipment offers NRR 26dB for use in high noise environments, but still allows workers to easily communicate without removing the earmuffs. The practice of “lifting off” earmuffs to hear can compromise attenuation and protection for wearers. These earmuffs have a listening mode capability to allow “outside the muff” sounds to be clearly heard when needed.
Exposure to loud noises can adversely affect the ability to hear over time. Wearing proper hearing protection devices can help in reducing the harmful effects of noise. Sounds levels are expressed in decibels, often abbreviated as dB. Higher decibel numbers indicate louder sounds. Typical decibel levels associated with common sounds include: outdoors with no people or traffic 20 dB, normal conversation 60 dB, power lawn mower 90 dB, chain saw 110 dB, and 12-gauge shotgun 165 dB. The hearing protector NRR can be used to evaluate different hearing protection options. However, the actual level of protection varies depending on fit, wearing time and other factors.
