目的 探讨畸变产物耳声发射(DPOAE)在船员噪声性听力损伤诊断中的应用价值.方法 100名船员(其中噪声性耳聋组52人,听阈正常组48人)为实验组,另外50名听力正常人为对照组.对2组人员进行纯音听力测定和DPOAE检测,比较2组的听阈值和DPOAE幅值及引出率.结果 噪声性聋组与对照组比较,所有频区听阚值差异均有统计学意义(P<0.05),噪声性聋组DPOAE幅值和引出率较对照组明显下降(P<0.05),随着接触噪声工龄的延长,DPOAE引出率逐渐下降(P<0.05).听阈正常组DPOAE幅值和引出率也较对照组明显下降(P<0.05).结论 船员早期噪声性听力损伤纯音听阈可能正常,应用DPOAE可用于船员噪声性听力损伤的早期诊断和评估.
目的 探討畸變產物耳聲髮射(DPOAE)在船員譟聲性聽力損傷診斷中的應用價值.方法 100名船員(其中譟聲性耳聾組52人,聽閾正常組48人)為實驗組,另外50名聽力正常人為對照組.對2組人員進行純音聽力測定和DPOAE檢測,比較2組的聽閾值和DPOAE幅值及引齣率.結果 譟聲性聾組與對照組比較,所有頻區聽闞值差異均有統計學意義(P<0.05),譟聲性聾組DPOAE幅值和引齣率較對照組明顯下降(P<0.05),隨著接觸譟聲工齡的延長,DPOAE引齣率逐漸下降(P<0.05).聽閾正常組DPOAE幅值和引齣率也較對照組明顯下降(P<0.05).結論 船員早期譟聲性聽力損傷純音聽閾可能正常,應用DPOAE可用于船員譟聲性聽力損傷的早期診斷和評估.

Objective To explore the application of the distortion product otoacoustic emission (DPOAE) in the diagnosis of noise-induced hearing damage for the ship crew.Methods The experimental group consisted of 100 crew members,among whom 52 had noise-induced hearing damage and 48 people had normal hearing thresholds.And another 50 people with normal hearing level were chosen as control.The two groups received acoustic emission,pure tone audiometry and DPOAE testing.Hearing thresholds,DPOAE amplitude and the provocation rate were compared between the two groups.Results Statistical differences could be noted in hearing thresholds in all frequency zones,when a comparison was made between the noise-induced hearing damage group and the control group ( P < 0.05 ).DPOAE amplitude and the provocation rate of the experimental group decreased significantly ( P < 0.05 ),when compared with those of the control group.With the extension of noise exposure,DPOAE provocation rate for the ship crew decreased ( P < 0.05 ).DPOAE amplitude and the provocation rate of the normal hearing level group also decreased more significantly than those of the control group (P < 0.05 ).Conclusions Pure-tone hearing threshold for the ship crew with early noise-induced hearing damage might be normal.DPOAE could be applied to early diagnosis and appraisal of early noise-induced hearing damage.
