Earmuff plus earplugs needed

Sordin provides the hearing protection you need to do your thing, even close to the world’s loudest machines. With noise well over 100 dB, airports are among the loudest work environments people can be subjected to. Here, hearing protection of the highest quality is an absolute must.

Even the most efficient hearing protectors, such as Sordin left/RIGHT High or Sordin Classic HPE, may not be sufficient to safely protect ground personnel. Here, it is necessary to combine over-the-ear (earmuff) and in-ear (ear plugs) hearing protection to achieve the necessary total attenuation level.

These professionals may also benefit from using a combination of an electronic hearing protector such as Sordin Sharp or Sordin Share, and an in-ear product such as Sordin SmartEar or SoftEar. The combined effect of these products would be sufficient to provide safe hearing protection at most airport environments.

Ambient sound support – perfect where there’s less noise

The electronic hearing protectors mentioned above all offer ambient sound support. While this feature would be of little use at 140 dB, it may prove valuable at parts of the airport where the noise level is slightly lower. Here, ambient sound would allow personnel to speak to each other while wearing their earmuffs and ear plugs.

Let’s look at an example. Sordin Share, which integrates hearing protection and voice communication in one and the same solution, has an SNR value of 29 dB. This is not sufficient to single-handedly protect against noise at, say, 130 dB. However, add Sordin SmartEar, with an SNR value of 20 dB, as complementary protection, and you will achieve the necessary attenuation to meet EU’s stipulated 85 dB for an 8-hour workday.

Boom mic enables crisp audio uptake

Sordin can offer other clever combinations of earmuffs and ear plugs, depending on noise environment and other specific requirements. For example, Sordin left/RIGHT CO CC has a proven record in racing thanks to its advanced audio uptake and reproduction capability, including an ultra-sensitive boom microphone, allowing for crisp and clear voice communication even at very high noise levels.
