In 1981, OSHA implemented new requirements to protect all workers in general industry (e.g. the manufacturing and the service sectors) for employers to implement a Hearing Conservation Program where workers are exposed to a time weighted average noise level of 85 dBA or higher over an 8 hour work shift. Hearing Conservation Programs require employers to measure noise levels, provide free annual hearing exams and free hearing protection, provide training, and conduct evaluations of the adequacy of the hearing protectors in use unless changes to tools, equipment and schedules are made so that they are less noisy and worker exposure to noise is less than the 85 dBA.
In real work, there are many noise positions. These positions have to face the noise because of the particularity of the work. For example, construction sites, Carpentry, mining workers, racers, airport dock workers, shooting targets, etc. In a noisy environment, how can we protect our hearing?
Noise-cancelling earmuffs are the best answer！
Earmuffs are objects designed to cover a person's ears for hearing protection or for warmth. They consist of a thermoplastic or metal head-band, that fits over the top or back of the head, and a cushion or cup at each end, to cover the external ears. Noise-cancelling earmuffs has the function of reducing noise and effectively protects the ear hearing.
*Factory floor worker
Especially in the factory floor, workers sometimes face strong production noise. Workers need to wear noise-reducing earmuffs to protect hearing from noise damage
Site workers sometimes need to operate high-noise machinery, such as cutting machines, electric drills, etc., and sometimes in high-noise construction environments, such as online command, etc. At this time, noise reduction earmuffs are needed to protect hearing.
*Lumberjacks, green chemical workers, floor cleaners
Chainsaws, lawn mowers, and large sweepers will generate a lot of noise. Operators of this type of machinery need to wear noise-reducing earmuffs to protect their ears, otherwise they will be disturbed by the noise of such machinery for a long time. The brain produces bad stimulation, which in turn causes mental illness
When the shooting is cleared, the target noise will reach 90 to 116dB, which is far beyond the safe noise range, so the target personnel usually need to wear noise reduction earmuffs to protect hearing.
Either the audience or the contestants, in high-noise sports events, you need a suitable frame structure earmuffs to protect yourself.
Wearing noise-cancelling earmuffs will allow you to have a relaxing journey.
The noise of F1 races is generally between 130 and 160 decibels. There are two main types of noise that drivers need to withstand in F1 races. The noise generated by the engine running at high speed and the airflow sound when the car is driving at high speed. To protect yourself, the people watching the game and the field control need to use noise reduction earmuffs to protect themselves, which is responsible for themselves.
*Filled with high-efficiency sound-absorbing sponge and flexible sponge ear pads for comfortable wearing
*Head-mounted headband retractable length, earmuffs can rotate 360 degrees
*Average noise reduction value 32dB
*EHN001 Head-mounted: suitable for use without the need to wear a helmet, such as shooting targets
*EHN002 rear hanging type: suitable for use when wearing a helmet, mostly used by workers wearing hard hats on site;
Noise-cancelling earmuffs are widely used in life and work. When you are in a noisy environment and you want to protect your hearing, then you need a noise-cancelling earmuff.
