为了探讨内耳黑色素的功能，研究了皮肤色素沉着与噪声性暂时性听力损失（TTS）的关系。44名听力正常的白人受试者根据对阳光的敏感度分为三组。在2-8千赫的频率范围内，用计算机扫描频率听力计确定暴露前后的听力阈值。噪声暴露包括1/3倍频带滤波噪声，中心频率为2 kHz，声压级为105 dB，持续10分钟。在2 ~ 8 kHz频率范围内，三组间TTS均值差异有统计学意义，即色素含量高的受试者TTS发生率最低，色素含量低的受试者TSS发生率最高。
In order to investigate the function of the inner ear melanin, the relationship between skin pigmentation and noise-induced temporary hearing loss (TTS) was studied. Forty-four normal-hearing Caucasian subjects were divided into three groups according to their sun sensitivity. Hearing thresholds before and after exposure were ascertained with a computerized sweep frequency audiometer in the frequency range 2-8 kHz. The noise exposure consisted of a 1/3-octave band-filtered noise with a centre frequency of 2 kHz at 105 dB SPL for 10 min. The mean TTS in the frequency range 2-8 kHz showed statistically significant differences between the three groups, i.e. the most pigmented subjects developed least TTS, and the least pigmented subjects most TSS.
