Anti-noise or protective headphones are a must for every master, working in noisy environments. Such, according to sanitary standards, premises are considered, where the noise level exceeds 80 dB. Experts note, that prolonged exposure can cause hearing loss. For example, about 80 db publishes a working drill. Earmuffs provide the most effective and comfortable protection.. Still have earplugs, but they are not always easy to use..

What are ear protectors?

Passive and active

According to the type of noise isolation, protective headphones are divided into passive and active.. Immediately worth noting, that the former are the most common.

Passive earmuffs are equipped with conventional earcups, filled with sound-absorbing material. The most common models reduce the sound pressure level by 20-30dB. At the same time, they drown out like extraneous noise., and the "necessary" sounds, For example, speech or danger signals.

Active ones are equipped with a system of microphones and speakers. They limit exposure to harmful noise, but the user can still hear speech and warning tones. Some models can be connected to third-party devices, For example, smartphones and radios, it is possible to adjust the level of reproduced sounds.

Sound insulation classes

Experts identify three classes of hearing protection devices. They are assigned depending on the acoustic efficiency., that is, from the amount of absorbed noise:

  • The first class includes models with acoustic efficiency or (SNR) in 27 dB, they are designed to work in rooms with a noise level 87-98 Db.
  • The second class has SNR 30 and more dB, they are used under conditions, when the sound pressure reaches 94-105 dB.
  • Third class - devices with SNR in 33 dB. Used for loud work 95-110 dB.

If the work is carried out at a volume above 110 dB, hearing protection devices combine, For example, together with anti-noise headphones, special pads or earplugs are used.

Criterias of choice

When choosing earmuffs, primarily, it is worth considering the terms of use. For infrequent use, e.g. home renovation, you can take the simplest option of the first class. This choice is primarily determined by the price of the model.. For professional use or industrial applications, possibly, you will need active noise-canceling headphones with a high level of noise reduction.

When choosing a device, it is worth trying it on. The collar must be adjustable, to ensure a comfortable fit on the head. If it is upholstered in soft material, wearing such protective earmuffs will be much more comfortable. Cups should fit snugly against the ear, desirable, so that they are also upholstered at the edges with soft material for a good fit to the head.
