Speech perception is the most important social task of the auditory system. Consequently, speech audiometry is essential to evaluate hearing aid benefit. The aim of the study was to describe the correlation between pure-tone hearing loss and speech perception. In particular, pure-tone audiogram, speech audiogram, and speech perception with hearing aids were compared.
In a retrospective study, 102 hearing aid users with bilateral sensorineural hearing loss were included. Pure-tone loss (PTA) was correlated to monosyllabic perception at 65 dB with hearing aid and with maximum monosyllabic perception with headphones.
Speech perception as a function of hearing loss can be represented by a sigmoid function. However, for higher degrees of hearing loss, substantial deviations are observed. Maximum monosyllabic perception with headphones is usually not achieved with hearing aids at standard speech levels of 65 dB.
For larger groups, average pure-tone hearing loss and speech perception correlate significantly. However, prognosis for individuals is not possible. In particular for higher degrees of hearing loss substantial deviations could be observed. Speech performance with hearing aids cannot be predicted sufficiently from speech audiograms. Above the age of 80, speech perception is significantly worse.
言语感知是听觉系统最重要的社交任务。因此，言语测听对于评估助听器效果至关重要。本研究的目的是描述纯音听力损失与言语感知之间的相关性。特别地，对纯音听力图、言语听力图以及佩戴助听器时的言语感知进行了比较。
在一项回顾性研究中，纳入了102例双侧感音神经性听力损失的助听器使用者。纯音听力损失（PTA）与佩戴助听器时65分贝下的单音节感知以及使用耳机时的最大单音节感知相关。
言语感知作为听力损失的函数可用S形函数表示。然而，对于较高程度的听力损失，会观察到明显偏差。在65分贝的标准言语水平下，佩戴助听器通常无法达到使用耳机时的最大单音节感知。
对于较大群体，平均纯音听力损失与言语感知显著相关。然而，无法对个体进行预后评估。特别是对于较高程度的听力损失，会观察到明显偏差。不能从言语听力图充分预测佩戴助听器时的言语表现。80岁以上人群的言语感知明显更差。
