Sound technicians like musicians are subjected to intense sound almost daily, despite the fact that their ears are their main work tools. Therefore, it is important that they take of them and protect them so that they can perform throughout their lives.

Today, more and more  use personal hearing protection with acoustic filters  from 9 to 15 dB.

Although some acknowledge that they don't wear them all the time, they like to wear them when the mix is done and the sound is going on. These filters reach all frequencies in a linear fashion, they provide very good listening quality, but  is not as loud depending on the filter you wear.

It is a little like controlling the volume at the entrance of your ear. You can remove them from time to time to control your mix, but the more you wear them the more you will soothe your ears and preserve your hearing potential the longest time possible.
