Industrial deafness is grouped into four main types temporary loss of hearing, permanent loss of hearing, acoustic trauma and tinnitus and the difficulty hearing can be a percentage of full hearing in one or both ears, or if suffering from tinnitus there will be the sensation of external noise when no external noise exists.
