切口噪聲前掩蔽對純音間隙偵測之頻率依賴效應

// Frequency-dependent effects of notched-noise forward maskers on pure-tone gap detection

本研究探討光譜形狀調整的前向掩蔽對不同頻率間隙檢測閾值（GDT）的影響｜60名正常聽力成人在安靜、白噪音與缺口噪音掩蔽下完成測試，結果顯示白噪音提升GDT，而缺口噪音則複雜且頻率依賴性地降低GDT｜研究指出光譜調整影響超出單通道效應，暗示更廣泛的聽覺適應機制存在。

// This study investigated how spectrally shaped forward maskers affect gap detection thresholds (GDTs) across different frequencies. Sixty normal-hearing adults completed a gap-detection task using tonal markers under quiet, white-noise, and notched-noise masking conditions. Results showed white-noise increased GDTs, while notched-noise maskers often lowered GDTs in a complex, frequency-dependent way. These findings suggest that spectral shaping influences gap detection beyond simple within-channel effects, indicating broader auditory adaptation mechanisms.
