助聽聽損者的知覺扭曲：過度響度增長與音色表徵改變的心理物理證據

// Perceptual Distortions in Aided Hearing-Impaired Listeners: Psychophysical Evidence of Excessive Loudness Growth and Altered Timbre Representation

本研究探討助聽器使用者是否存在異常的音量處理與音色感知失真｜結果顯示助聽器無法完全恢復正常音量增長，且改變音色感知，強調時間特徵並扭曲粗糙度｜這些失真可能導致日常聲音過度顯著，需進一步研究其對聲音突出感的影響。

// This study examined whether hearing aid users experience abnormal loudness processing and distorted timbre perception, which may cause some sounds to seem overly intrusive. Using loudness and timbre tests with normal-hearing and aided hearing-impaired listeners, researchers found that hearing aids do not fully normalize loudness growth and alter timbre perception by emphasizing temporal features and distorting roughness. These distortions likely contribute to the abnormal salience of everyday sounds in hearing aid users. Further research is needed to directly measure how these perceptual changes affect sound salience.
