Hearing protection

Did you know that from 85 dB noise level onwards hearing protection is mandatory?

Numerous situations in everyday (working) life expose our hearing to potentially harmful noise. In order to prevent irreparable hearing damage, such as tinnitus or complete loss of hearing, the use of professional hearing protection is mandatory from a noise level of 85 dB. DIN EN 352 specifies individual measures for noise protection and the acoustic insulation value of hearing protection.

In order to prevent irreversible hearing damage, wearing hearing protection is mandatory in environments with high noise levels - for example, when working near noisy machines above 85 dB. Protect your hearing from noise and vibration with ear plugs, banded ear plugs and ear defenders.


HOW LONG MUST I WEAR MY HEARING PROTECTION?

In noisy environments it is essential that hearing protection is worn 100%, as even short breaks in wearing will lead to a significant loss of protection.

WHAT IS THE RIGHT HEARING PROTECTION FOR ME?

The first step in choosing the right hearing protection is to determine the noise exposure at the workplace. In the second step, the personal preferences and other personal protective equipment of the wearer should be taken into account.

Checks of the actual protective effect of hearing protectors show that the attenuation values achieved during testing are usually not achieved in practice. For this reason, the following correction values must be considered when selecting suitable hearing protection:

  • Preformed disposable ear plugs: 9 dB
  • Preformed reusable ear plugs: 5 dB
  • Banded ear plugs: 5 dB
  • Capsule ear protection: 5 dB

In other words, if the noise level is 100 dB and the worker wants to use banded  ear plugs, you should choose ear plugs with a sound attenuation value of at least 25 dB. Then, taking into account the correction value, the worker's hearing is exposed to a noise level of max. 80 dB.
It is important to ensure that neither under- nor over-protection takes place. Dangers of underprotection are long-term, irreversible hearing damage, whereas overprotection leads to comprehension problems and isolation.
