摘要

在多声源环境中,辨别声源在空间中的位置的能力对于空间感知和交流具有重要的生态学意义。虽然助听器和人工耳蜗(CIs)可以支持一些使用者的空间听力,但这种能力并没有在临床上进行常规评估。本研究比较了在-54°至+54°方位角的18°间隔上使用真实声源和在-54°和+54°位置上使用振幅平移模拟的虚拟声源对200 ms语音噪声的声源定位。参与者是34名成年CI或电声刺激使用者,包括单侧耳聋或辅助声学听力的个体。参与者的定位错误模式在真实来源和虚拟来源中大致相似,有一些适度的差异。例如,这两种情况的均方根(RMS)误差在r = 0.89时相关(p

Estimating Cochlear Implant Users' Sound Localization Abilities With Two Loudspeakers.

The ability to tell where sound sources are in space is ecologically important for spatial awareness and communication in multisource environments. While hearing aids and cochlear implants (CIs) can support spatial hearing for some users, this ability is not routinely assessed clinically. The present study compared sound source localization for a 200-ms speech-shaped noise presented using real sources at 18° intervals from -54° to +54° azimuth and virtual sources that were simulated using amplitude panning with sources at -54° and +54°. Participants were 34 adult CI or electric-acoustic stimulation users, including individuals with single-sided deafness or aided acoustic hearing. The pattern of localization errors by participant was broadly similar for real and virtual sources, with some modest differences. For example, the root mean square (RMS) error for these two conditions was correlated at r = .89 (p < .001), with a mean RMS elevation of 3.9° for virtual sources. These results suggest that sound source localization with two-speaker amplitude panning may provide clinically useful information when testing with real sources is infeasible.

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.
