Abstract

• It is well known that the ototoxicity resulting from the use of aminoglycoside antibiotics in experimental animals can be augmented by intense sound. However, the dose-effect relationship of this interaction is not known. This study was designed to determine the shape of this dose-effect relationship in guinea pigs at sound intensities approaching those that would be experienced by patients receiving aminoglycoside antibiotics. We found a linear relationship between the probit of the percent of missing cochlear outer hair cells and decibel-A scale sound intensity when the animals were treated with kanamycin plus white noise ranging from 115 to 45 dBA.
