Noise exposure in the fire department

This paper discusses noise exposure to firefighters on the job and whether this contributes to noise induced hearing loss.

The effects of noise exposure on nitric oxide synthase knockout mice

This paper studies the role of nitric oxide (NOS 1, NOS 2, and NOS 3 genes) in the mouse cochlea and in noise-induced hearing loss (NIHL). Mice genetically deficient of the NOS 2 and NOS 3 genes were protected from NIHL, indicating that one or both of these genes may be responsible for producing nitric oxide that damages the inner ear when exposed to harmful levels of noise.
