Music Appreciation after Cochlear Implantation

人工耳蜗植入后的音乐欣赏

基本信息

项目摘要

PROJECT SUMMARY Cochlear implants are medical devices that restore a remarkable degree of hearing to people who would otherwise be profoundly deaf. These devices generally restore enough hearing that recipients can understand spoken speech even in noisy environments. However, most recipients express dissatisfaction with music. This proposal centers on understanding the challenges that implant users face and the strategies that they adopt as they learn to appreciate music with this new way of hearing. The proposed research is organized into three aims: Aim 1: Characterize music appreciation after cochlear implantation. The proposed research balances qualitative and quantitative methods to examine the emergence of music appreciation after cochlear implantation. Qualitative methods will include semi-structured interviews and focus groups designed to clarify the obstacles that implant users face as they learn to appreciate music with their new sense of hearing. Quantitative methods include surveys of music appreciation and quality of life, and auditory assessments of music and speech perception. The primary hypothesis is that music appreciation is predictive of key domains of quality of life including positive affect and well-being, and satisfaction with social roles and activities. Aim 2: Determine if pitch training improves cochlear implant speech comprehension. The proposed research tests for a causal relationship between pitch salience and key features of speech perception including talker discrimination, prosody detection, and speech recognition in competing speech. Cochlear implant users and their normal-hearing peers will take part in a crossover study to determine if pitch training improves aspects of music and speech perception compared to a visual task used as a control. The primary hypothesis is that pitch training will improve speech comprehension for cochlear implant users, but not for their normal-hearing peers. Aim 3: Test the limits of pitch coding in cochlear implants. The proposed research bypasses conventional sound processing to study the salience of pitch provided by electrode location and stimulation rate. These two stimulation cues are the primary cues for providing a sense of pitch to cochlear implant users. Our work has shown that implant users are able to learn to use this information to hear pitch with better resolution far better than previously thought. The primary hypothesis is that cochlear implant users have a latent ability to hear pitch associated with stimulation rate, but that they require experience to learn how to hear this new information. In each aim, we compliment psychophysical methods with an innovative approach combining EEG and near- infrared spectroscopy. The results will establish the importance of music training for improving cochlear implant outcomes, both in terms of hearing abilities and quality of life. The results will lead to changes in how music is encoded into implant stimulation, providing better outcomes for recipients. More generally, this project will shape understanding of neural coding of music and its role in social adjustment following traumatic experiences.
项目摘要 人工耳蜗是医疗设备 否则会深深地聋。这些设备通常会恢复足够的听力,以至于收件人可以理解 即使在嘈杂的环境中,语音也是如此。但是,大多数接受者对音乐表示不满。这 提案集中于了解植入用户面临的挑战以及他们采用的策略 他们通过这种新的听力学习学会欣赏音乐。拟议的研究分为三个目标: 目标1:表征人工耳蜗后的音乐欣赏。拟议的研究平衡 定性和定量方法,以检查耳蜗后音乐欣赏的出现 植入。定性方法将包括半结构化访谈和旨在澄清的焦点小组 植入用户学会以新的听觉欣赏音乐时面临的障碍。 定量方法包括对音乐欣赏和生活质量的调查,以及对 音乐和言语感知。主要假设是音乐欣赏是预测的 生活质量,包括积极的影响和福祉,以及对社会角色和活动的满意。 目标2:确定音高训练是否改善了人工耳蜗的语音理解。提议 研究测试对音调显着性与语音感知的关键特征之间的因果关系进行了研究测试 说话者的歧视,韵律检测和语音识别在竞争性言论中。人工耳蜗用户 他们的正常听觉同龄人将参加一项跨界研究,以确定音高训练是否改善了方面 音乐和语音感知与用作控制的视觉任务相比。主要假设是音调 培训将改善人工耳蜗使用者的语音理解,但不能为他们的正常听证同行提供言语理解。 AIM 3:测试人工耳蜗植入物中俯仰编码的极限。拟议的研究绕过了传统的 声音处理以研究电极位置和刺激速率提供的音高的显着性。这两个 刺激提示是为人工耳蜗用户提供音调感的主要提示。我们的工作有 表明植入物用户能够学习使用此信息以更好的分辨率听到音调 比以前想的。主要假设是人工耳蜗使用者具有潜在的声音能力 与刺激率相关,但他们需要经验来学习如何听取此新信息。 在每个目标中,我们都将心理物理方法与一种创新的方法相称 红外光谱。结果将确定音乐培训对改善人工耳蜗植入物的重要性 在听力能力和生活质量方面的成果。结果将导致音乐的变化 编码为植入物刺激,为接受者提供更好的结果。更一般地,这个项目将成型 了解音乐的神经编码及其在创伤经历后的社会调整中的作用。
