To quantify the intensity, spectral content, and duration of exposure for suction noise created during aspiration of middle ear fluid following myringotomy.
Case series.
Tertiary care center.
Convenience sample of 245 myringotomies performed on 124 patients ranging in age from 6 months to 14 years (mean age, 2 years 8 months).
Intensity, spectral content, and duration of exposure associated with suction noise were defined by electroacoustic analysis of high-fidelity tape recordings of the noise created during suctioning middle ear fluid.
The intensity of suction noise ranged from 74 to 117 dB; most acoustic energy was concentrated in the frequency range between 1.7 and 6.0 kHz, and the duration of exposure varied from 4 to 23 seconds.
量化鼓膜切开术后中耳积液抽吸过程中产生的抽吸噪声的强度、频谱成分和暴露持续时间。
病例系列。
三级医疗中心。
对124例年龄在6个月至14岁（平均年龄2岁8个月）的患者进行245次鼓膜切开术的便利样本。
通过对中耳积液抽吸过程中产生的噪声的高保真磁带录音进行电声分析，确定与抽吸噪声相关的强度、频谱成分和暴露持续时间。
抽吸噪声强度范围为74至117分贝；大部分声能集中在1.7至6.0千赫的频率范围内，暴露持续时间从4秒到23秒不等。
