The objectives of this study was to present wideband tympanometry (WBT) data and absorbance with normal hearing and normal middle ear status.
Data were collected in 99 adult Caucasians with normal hearing and middle ear status. Energy absorbance was measured with an Interacoustics Titan using clicks for 1/24-octave frequency-intervals (0.226-8 kHz) with the ear canal air pressure alternated using a descending pressure sweep from + 250 to - 350 daPa.
From the wideband energy absorbance tympanograms, the mean energy absorbance tympanogram, wideband averaged tympanogram and parameters such as ear canal volume, middle ear pressure and resonance frequency were determined.
This study established a dataset containing descriptive analysis of wideband tympanograms and its derived parameters in Caucasian adults with normal hearing and normal middle ear conditions. The data presented in this study may serve as a future reference for WBT studies with Caucasian adults.
本研究旨在呈现正常听力和中耳状态下的宽频带鼓室图（WBT）数据和吸声值。
本研究纳入了 99 名听力正常和中耳状态正常的成年白种人。采用 Interacoustics Titan，使用短声在 1/24 倍频程频率间隔（0.226-8 kHz）下测量能量吸声值，通过从+250 至-350 daPa 的下降压力扫描交替测量耳道气压。
从宽频带能量吸声鼓室图中，确定了平均能量吸声鼓室图、宽频带平均鼓室图以及耳道容积、中耳压力和共振频率等参数。
本研究建立了一个包含正常听力和正常中耳条件下白种人宽频带鼓室图及其衍生参数描述性分析的数据集。本研究中提供的数据可作为未来白种人宽频带鼓室图研究的参考。
