Title: Hearing loss and cochlear pathology in monkeys after noise exposure. Author: Hawkins JE, Johnsson LG, Stebbins WC, Moody DB, Coombs SL. Journal: Acta Otolaryngol; 1976; 81(3-4):337-43. PubMed ID: 817561. Abstract: Old World monkeys were exposed to octaveband noise from 0.5 to 8 kHz at 120 dB SPL, 8 hours daily for 20 days. Restricted permanent threshold shifts and localized loss of outer hair cells were produced, which were reasonably well correlated with the exposure frequencies. There was also a loss of both inner and outer hair cells at the extreme basal end of Corti's organ, regardless of the exposure frequency. Implications for human inner ear pathology are discussed.[Abstract] [Full Text] [Related] [New Search]
