Best Hearing Protection Devices in delhi


Audio Visual Aids provides wide variety of types of hearing protectors available, including ear muffs, foam and preformed ear plugs, and canal caps. When selecting hearing protection, people usually focuses on the product’s Noise Reduction Rating (NRR), presuming that the one with the highest rating is the best choice. We would suggest that this is not the best approach because no matter how much noise reduction they offer, if they’re not comfortable, they’re not likely to be worn properly or even worse, at all. Selection of hearing protectors Hearing protectors are to be used for the purpose of reducing noise to a level where the risk of hearing damage is reduced, and, at the same time, allow the individual to hear instructions or warnings in the work environment. Generally speaking the effect of wearing a hearing protector should be similar to if you were to cup your hands over your ears.

Top 3 things you need to know when selecting hearing protectors:

  • A hearing protector should only provide the appropriate amount of noise reduction for the environment in which it will be used. Any less and it won’t do its job. Any more and you may get complaints such as “I can’t hear anything with these on”! The goal is to get the noise exposure down to a safe level – around 80dB (decibels).

  • Hearing protectors come with an NRR rating that indicates how many decibels of noise reduction they provide. An NRR20 should reduce the noise by 20dB, an NRR30 should reduce it by 30dB, and so on. The problem is that NRR ratings are established under ideal laboratory conditions. In the real world people don’t always get a proper fit.

  • Ensure there is enough attenuation to safeguard one’s hearing while not endangering the user from being able to properly hear and interpret warning signals.
