啾聲誘發之電耳蝸圖與正常聽力耳鳴者之噪音中語音辨識能力

// Chirp-Evoked Electrocochleography and Speech-in-Noise Performance in Normal-Hearing Individuals With Tinnitus

本研究透過調頻聲刺激誘發的電耳蝸圖（ECochG）與噪音中語音感知（SPIN）測試，探討正常聽力但有耳鳴者的耳蝸突觸病變指標｜結果顯示耳鳴組AP2波幅減弱，且對照組在困難聽覺條件下AP2波幅與SPIN表現呈正相關｜研究指出兩種測試結合可非侵入性評估耳鳴及語音辨識功能，具臨床應用潛力。

// This study investigated cochlear synaptopathy indicators in normal-hearing individuals with tinnitus using chirp-evoked electrocochleography (ECochG) and speech perception in noise (SPIN) tests. Results showed reduced AP2 amplitudes in the tinnitus group and a positive correlation between AP2 amplitude and SPIN performance in controls under difficult listening conditions. The findings suggest that combining chirp-evoked ECochG and SPIN testing offers complementary, noninvasive insights into auditory function related to tinnitus and speech-in-noise perception.
