项目摘要

DESCRIPTION (provided by applicant): Most modern day cochlear implant (CI) candidates have residual acoustic hearing in one or both ears. Several studies have shown that this residual hearing provides significant benefit when paired with a CI a bimodal listening configuration. The degree of acoustic-related, bimodal benefit however, varies across ears and is not correlated with audiometric threshold, etiology, age or preoperative speech recognition. In the absence of gross differences in preoperative hearing acuity, patients presenting with residual hearing in both ears are commonly told that either ear could provide benefit when paired with a CI. There is no clinical measure that provides predictive utility for selecting the er to be implanted-a critical consideration particularly in cases for which bilateral cochlear implantation may be restricted (i.e. insurance restrictions). This application proposes to develop and implement such a clinical tool. The clinical test of spectral modulation detection (SMD) is a modified version of a validated psychophysical procedure assessing spectral resolution. In this task, the listener is asked to discriminate spectrally-flat noise from spectrally-modulated noise. Pilot work on this clinical procedure has shown SMD in the non-implanted ear is an excellent predictor of acoustic benefit (r = 0.89) when paired with a CI for bimodal hearing. Because this task contrasts noise stimuli, it does not require speech understanding and can be completed by candidates with very little residual hearing-both of which are expected for individuals being evaluated preoperatively. Pilot work with our most recent iteration of the clinical task takes 5 to6 minutes per ear, is highly correlated with acoustic benefit in quiet and noise, and is reported as a percent correct score. This tool has the potential to satisfy a strong need in the fields of audiology and otology as well as significantly influence surgical decisions and patient outcomes.

描述（由申请人提供）：大多数现代人工耳蜗（CI）候选者在一只或两只耳朵中都有残留的声学听力。几项研究表明，这种残留听力与CI双峰聆听配置相结合时，可为您带来重大好处。然而，与声学相关的双峰益处的程度在耳朵之间有所不同，与听力学阈值，病因，年龄或术前语音识别无关。在术前听力敏锐度上没有严重差异的情况下，通常告诉两只耳朵中均可听力的患者，与CI配对时，两只耳朵都可以提供好处。没有临床措施可以提供预测效用以选择欧元植入的植入 - 特别是在双边耳蜗植入可能受到限制（即保险限制）的情况下。该应用程序建议开发和实施这种临床工具。光谱调制检测（SMD）的临床测试是评估光谱分辨率的经过验证的心理物理程序的修改版本。在此任务中，要求听众将频谱噪声与光谱调节的噪声区分开。该临床程序的试验性工作已在非植入的耳朵中表明SMD是当与CI配对以进行双峰听力时，是声学益处的出色预测指标（r = 0.89）。由于此任务与噪声刺激形成了鲜明的对比，因此它不需要语音理解，并且可以由候选人完成，而剩余的听力很少，预期的是术前评估的个人。飞行员与我们最新的临床任务迭代每耳朵需要5至6分钟，与安静和噪音中的声学益处高度相关，据报道为正确的分数百分比。该工具有可能满足听力学和耳科领域的强大需求，并显着影响手术决策和患者的结果。
