Abstract

Extended high-frequency (EHF) hearing loss offers a model for investigating the onset of auditory dysfunction before changes in standard audiometric thresholds occur. However, the impact on auditory perception remains poorly understood. This study evaluated the relationship between EHF hearing sensitivity and monaural and binaural measures of auditory temporal resolution and spatial release from masking in young adults (aged 20–35 years) with normal hearing thresholds in the clinical frequency range (.25 - 8 kHz) with varying degrees of hearing sensitivity in the EHFs (10 – 16 kHz). Despite considerable individual variability in performance on perceptual tasks, no significant correlations were found between EHF thresholds and measures of temporal processing or speech perception. This suggests that certain aspects of auditory processing within the standard audiometric frequency range may remain unaffected in individuals with EHF hearing loss.

研究扩展高频可听性在时间包络处理和空间释放中的作用

扩展高频（EHF）听力损失为研究标准听力阈值发生变化之前听力功能障碍的发生提供了一个模型。然而，对听觉感知的影响仍然知之甚少。本研究评估了在临床频率范围内听力阈值正常的年轻成年人（20-35岁）中EHF听力敏感性与单耳和双耳听觉时间分辨和空间释放的关系。25 - 8千赫)，在ehf（10 - 16千赫）中有不同程度的听力灵敏度。尽管在感知任务中的表现存在相当大的个体差异，但在EHF阈值与时间处理或语音感知测量之间没有发现显著的相关性。这表明，在标准听力测量频率范围内，EHF听力损失患者的听觉处理的某些方面可能不受影响。

期刊介绍： The aim of the journal is to provide a forum for papers concerned with basic peripheral and central auditory mechanisms. Emphasis is on experimental and clinical studies, but theoretical and methodological papers will also be considered. The journal publishes original research papers, review and mini- review articles, rapid communications, method/protocol and perspective articles. Papers submitted should deal with auditory anatomy, physiology, psychophysics, imaging, modeling and behavioural studies in animals and humans, as well as hearing aids and cochlear implants. Papers dealing with the vestibular system are also considered for publication. Papers on comparative aspects of hearing and on effects of drugs and environmental contaminants on hearing function will also be considered. Clinical papers will be accepted when they contribute to the understanding of normal and pathological hearing functions.
