Abstract

The magnitude and time course of the overshoot effect in listeners with normal hearing and those with high-frequency hearing loss have been reported. Some normal hearing young adult subjects show little or no overshoot and some older adult subjects show larger degrees of overshoot. A sensorineural hearing loss may disrupt the mechanisms for a large overshoot effect in the frequency region of the hearing loss. The detection threshold for a signal near masker onset improves and reduces overall degree of overshoot, with temporary hearing loss using either intense sound exposure. Larger overshoot effects are observed in the presence of broadband maskers than maskers of a single critical bandwidth.
