DESCRIPTION (provided by applicant): A common complaint of listeners with hearing loss is understanding speech in the presence of background noise. In most listening situations, the "noise" that masks a target talker is other voices. Realistic environments often have adverse listening conditions, such as reverberation and multiple sound sources. There are conflicting results reported in previous literature as to whether adults should use one or two hearing aids to best understand speech in noisy listening situations and it has been suggested that binaural interference increases with age. The goal of the proposed research is to determine whether removing one hearing aid helps or hinders speech understanding in complex listening situations. Auditory perceptual experiments will be conducted in younger and older adult listeners with sensorineural hearing loss to address three specific aims. First, to compare unilateral to bilateral amplification in multitalker listening environments. Second, to examine the effect of age on perceptual segregation of speech under conditions of informational masking. Third, to assess the effect of reverberation on aided speech understanding with multiple, simultaneous talkers. Overall, the results will be useful to audiologists and their patients.

描述（由申请人提供）：听力损失听众的一个常见抱怨是在背景噪音存在的情况下理解语音。在大多数聆听情况下，掩盖目标说话者的“噪音”是其他声音。现实环境通常具有不利的聆听条件，例如混响和多个声源。关于成年人是否应该使用一个或两个助听器才能在嘈杂的聆听环境中更好地理解语音，先前的文献报道了相互矛盾的结果，并且有人认为双耳干扰随着年龄的增长而增加。拟议研究的目标是确定摘除助听器是否有助于或妨碍复杂听力情况下的语音理解。听觉感知实验将在患有感音神经性听力损失的年轻和老年听众中进行，以实现三个具体目标。首先，比较多人聆听环境中的单侧放大和双边放大。其次，研究年龄对信息掩蔽条件下言语感知隔离的影响。第三，评估混响对多个同时讲话者的辅助语音理解的影响。总体而言，结果将对听力学家及其患者有用。
