Poor spectral resolution can be a limiting factor for hearing impaired listeners, particularly for complex listening tasks such as speech understanding in noise. Spectral ripple tests are commonly used to measure spectral resolution, but these tests contain a number of potential confounds that can make interpretation of the results difficult. To measure spectral resolution while avoiding those confounds, a modified spectral ripple test with dynamically changing ripples was created, referred to as the spectral-temporally modulated ripple test (SMRT). This paper describes the SMRT and provides evidence that it is sensitive to changes in spectral resolution.
较差的光谱分辨率可能是听力障碍者的一个限制因素,特别是在复杂的听力任务中,如在噪声中理解语音。频谱波纹测试常用于测量光谱分辨率,但这些测试包含一些可能使结果解释变得困难的潜在混淆因素。为了在避免这些混淆因素的情况下测量光谱分辨率,创建了一种具有动态变化波纹的改进频谱波纹测试,称为频谱时变波纹测试(SMRT)。本文描述了 SMRT 并提供了证据表明它对光谱分辨率的变化敏感。
