Abstract
For 11 patients with tinnitus and sensorineural hearing loss, the intensity of bilateral broad-band noise required to mask the tinnitus increased by as much as 41 dB over a 30-minute period. A significant correlation was obtained between the rate of change in the noise over time and reported annoyance of the tinnitus as measured on a 5-point rating scale. The total change in the noise level and the initial noise level required to mask the tinnitus were not significantly correlated with the annoyance of the tinnitus.
