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.
