调查１５个舞厅乐队，以１０２名演奏员为接触组，用不接触噪声的机关干部作配对调查（对照组），接触组声级为８０～９８ｄＢ（Ａ），７５％的测定点在８５ｄＢ（Ａ）以上，超过９０ｄＢ（Ａ）的测定点占４１．６％。对照组测定点全部在７０ｄＢ（Ａ）以下，高频听力损伤接触组４２耳，检出率２０．５％，对照组６耳，检出率２．９％，轻度语频听力下降，接触组６耳，检出率２．９％，对照组未检出。接触组与对照组听力损伤检出率差别有高度显著性（Ｐ＜０．０１）。产生两组听力损伤差别的原因是接触组长期接触高强度舞厅乐队声响，对照组则接触低于卫生标准的声响。本次调查说明长期接触高强度舞厅乐队声响，会使演奏员的听力造成损伤。
A total of 15 dance halls were investigated, with 102 performers as the contact group and non-noise-related cadres as the counterpart (control group). The contact group had a sound level of 80-98 dB (A), 75% of the measurement points were at 85 dB A) or above, measurement points exceeding 90 dB (A) accounted for 41.6%. The control group had all the measurement points below 70dB (A), 42 ears of the high-frequency hearing impairment group had a detection rate of 20.5%, 6 ears of the control group had a detection rate of 2.9%, mild speech hearing loss and contact Group 6 ears, the detection rate of 2.9%, the control group was not detected. There was a significant difference in the detection rate of hearing loss between the exposure group and the control group (P <0.01). The reason for the difference in hearing loss between the two groups was that the exposure group had long-term exposure to the sound of a high-intensity ballroom dance group while that of the control group was exposed to a sound lower than the hygiene standard. The survey shows that long-term exposure to high-intensity ballroom sound will make the player’s hearing damage.
