Some information:

noise protectors are devices that serve as personal means of noise protection for flight and engineering personnel and prevent noise injuries to the hearing organs.

It is known that human internal organs have their own oscillation frequencies ranging from 2 to 80 Hz. When the frequency of the noise and the frequency of oscillations of the internal organs coincide, resonance phenomena occur, which cause the occurrence of pain sensations. Therefore, to protect against exposure to noise with high (more than 125 dB) sound pressure levels (SPL), helmets and anti-noise suits are used that cover the head and body of a person.

The set of noise protection equipment includes a noise protection helmet, an anti-vibration noise protection belt (vest, overalls), which should reduce the overall noise level in the underwear space in the chest and abdomen by 5 ... 25 dB (at the frequency of noise vibrations - 125...8000 Hz).
