Hearing Loss Among LSAH Participants (LSAHNEWSV14_1_1)
Research Area:
Species Studied
Scientific Name: Homo sapiens Species: Human

Noise is one of the most common causes of hearing loss, and noise-induced hearing loss (NIHL) is the most common occupational illness in the United States. The effects of noise on hearing are often underestimated because the damage takes place so gradually, without pain, and cannot be visibly detected because the delicate inner ear is buried deep in the skull. Audiometric testing, using pure tone stimuli, has been the traditional method of monitoring hearing loss. Hearing tests have always been part of NASA’s hearing conservation program for personnel exposed to hazardous noise from aircraft and other equipment. Audiometric data from the Longitudinal Study of Astronaut Health (LSAH) database was reviewed in order to assess trends and compare data with other population studies.
