中文摘要 | 我們對20名健康年輕人(40耳)做歪成份耳聲傳射(DPOAEs)檢查,以建立正常 值分布資料。 共以 6 種不同的音壓強度測試: 分別為 60-60、 65-65、 70-70、75-75、 65-50、以及 70-55 dB SPL。測試同時並記錄 DPOAE 附近頻率的背景噪音值。 在此刺激範 圍內,當兩純音音壓 L1=L2 時,DPOAE 強度隨刺激音強度而增加; 而在相同 L1 下,刺激 音 L1=L2+15 dB 所得之 DPOAE 強度與 L1=L2 所得者無顯著差異,但變異量較大。 背景噪 音約在 -12.5 至 -5.5 dB SPL 之間,低頻噪音值較高。(中耳醫誌 1997;32:1-6。) |
英文摘要 | Distortion product otoacoustic emissions (DPOAEs) were measured in 20 young adults (40 ears). All of them had normal hearing and no history of otologic disease. Six pairs of pure tone were used to establish the normal range of DPOAE-grams: The stimuli were 60-60, 65-65, 70-70, 75-75, 65-50, and 70-55 dB SPL. Base line noise was also measured around the frequencies of DPOAEs. With the primary tone level L1=L2, the amplitude of DPOAEs grossly increased with that of the stimuli from 60 to 75 dB SPL. Under the same L1, the amplitude of DPOAEs stimulated by primaries L1=L2+15 dB was not significantly different from that stimulated by L1=L2, but the variance of the former was larger. The base line noise level was between-12.5 and -5.5 dB SPL, and with higher level at lower frequencies. |
