Abstract

Audiological use of the 40 Hz-ASSR (auditory steady state responses) could be valuable for objectively estimating the frequency-specific threshold in adults undergoing an expertise examination for medicolegal and/or compensation purposes. The present prospective study was set up to clarify the relationship between the thresholds obtained by cortical evoked response audiometry (CERA) and by 40 Hz-ASSR, in the same ears, within a large homogeneous sample of 164 subjects (328 ears) with NIHL and well documented exposure to noise. All these subjects claimed financial compensation for occupational NIHL, and there was a suspicion of exaggeration of the reported NIHLs. ASSR thresholds show a good correlation with the CERA thresholds. However, a systematic shift is noticed, ASSR thresholds being on average (1–2 – 3 kHz) 4.38 dB lower (i.e. showing less hearing loss) than CERA thresholds. Moreover, the binaural multiple ASSR technique allows a considerable time gain when compared to the CERA.

在职业性NIHL病例中用于医学法律目的的客观频率特异性听力阈值定义:ASSR优于CERA

听力学上使用40hz - assr(听觉稳态反应)对于客观估计因医学和/或赔偿目的而接受专业知识检查的成年人的频率特异性阈值可能是有价值的。本前瞻性研究旨在阐明皮质诱发反应听力学(CERA)和40hz - assr获得的阈值之间的关系，这些阈值是在相同的耳朵中，在164名患有NIHL且有充分记录的噪音暴露的受试者(328只耳朵)中获得的。所有受试者都要求对职业NIHL进行经济补偿，并且存在夸大NIHL报告的嫌疑。ASSR阈值与CERA阈值具有良好的相关性。然而，我们注意到一个系统性的变化，ASSR阈值平均(1-2 - 3 kHz)比CERA阈值低4.38 dB(即显示更少的听力损失)。此外，与CERA相比，双耳多重ASSR技术可以获得相当大的时间增益。

期刊介绍： Journal of Otology is an open access, peer-reviewed journal that publishes research findings from disciplines related to both clinical and basic science aspects of auditory and vestibular system and diseases of the ear. This journal welcomes submissions describing original experimental research that may improve our understanding of the mechanisms underlying problems of basic or clinical significance and treatment of patients with disorders of the auditory and vestibular systems. In addition to original papers the journal also offers invited review articles on current topics written by leading experts in the field. The journal is of primary importance for all scientists and practitioners interested in audiology, otology and neurotology, auditory neurosciences and related disciplines. Journal of Otology welcomes contributions from scholars in all countries and regions across the world.
