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.
对于11例患有耳鸣和感音神经性听力损失的患者，在30分钟内，掩盖耳鸣所需的双侧宽带噪声强度增加了多达41分贝。随着时间推移，噪声变化率与通过5分制评定量表测得的耳鸣烦恼程度之间存在显著相关性。噪声水平的总变化以及掩盖耳鸣所需的初始噪声水平与耳鸣烦恼程度无显著相关性。
