This not only a set back in production but potential situation for an accident. The solution comes from an electronic muff , a product of Hellberg from Sweden. React has two microphones that are enhancing speech , warning signals and useful sound. The harmful noise is canceled , by the two speakers equipped inside the muff , that produce opposite noise.
Another benefit is that has socket , in which you can plug any external source of sound like radio , mp3 player , communication systems e.t.c.
