Abstract

Individuals with tinnitus hear sounds that are not present in the external environment. Whereas hearing difficulties at frequencies near those matching the tinnitus pitch are a common complaint for individuals with tinnitus, it is unclear to what extent the internal tinnitus sounds interfere with the detection of external sounds. We therefore studied whether pure-tone detection at the estimated frequency corresponding to the tinnitus pitch (ftp) was affected by confusion with the tinnitus percept. Signs of confusion would be a high false alarm rate or a shallower slope of the psychometric function for tone detection at ftp. We selected participants with symmetric, tonal tinnitus, who were able to estimate its pitch consistently (n = 18). Another 18 participants matched for high-frequency hearing loss, age, and sex, but without tinnitus, served as the control group. For both groups, we measured the psychometric function for detecting long-duration tones, maximizing the likelihood for confusion with an external sound. We observed that false alarm rates for tinnitus participants were not higher for test tones at ftp, nor were they higher than for the control group without tinnitus. Similar results were obtained for the slopes of the psychometric functions. Apparently, individuals with tinnitus are well able to discriminate between their own tinnitus and comparable external sounds. Our results indicate that (tonal) tinnitus does not interfere with the detection of soft sounds at the tinnitus pitch-matched frequency.

音调耳鸣不干扰音调检测在耳鸣音高匹配频率。
患有耳鸣的人会听到外部环境中不存在的声音。虽然耳鸣患者在接近耳鸣音高的频率时听力困难是一种常见的抱怨,但目前尚不清楚内部耳鸣声音在多大程度上干扰了对外部声音的探测。因此,我们研究了在耳鸣音高(ftp)对应的估计频率下的纯音检测是否受到与耳鸣感知混淆的影响。混淆的迹象将是高虚警率或在ftp音调检测的心理测量函数斜率较浅。我们选择了对称性、音调耳鸣的参与者,他们能够一致地估计其音高(n = 18)。另外18名高频听力损失、年龄和性别匹配的参与者作为对照组,但没有耳鸣。对于这两组,我们测量了检测长时间音调的心理测量功能,最大限度地提高了与外部声音混淆的可能性。我们观察到,耳鸣参与者的假警报率并不高于ftp测试音调,也不高于没有耳鸣的对照组。心理测量函数的斜率也得到了类似的结果。显然,耳鸣患者能够很好地区分自己的耳鸣和类似的外部声音。我们的研究结果表明,(音调)耳鸣不会干扰在耳鸣音高匹配频率的软声音的检测。

期刊介绍: Trends in Hearing is an open access journal completely dedicated to publishing original research and reviews focusing on human hearing, hearing loss, hearing aids, auditory implants, and aural rehabilitation. Under its former name, Trends in Amplification, the journal established itself as a forum for concise explorations of all areas of translational hearing research by leaders in the field. Trends in Hearing has now expanded its focus to include original research articles, with the goal of becoming the premier venue for research related to human hearing and hearing loss.
