摘　　要：为探讨风洞噪声对左心功能的影响，用二维彩色多普勒超声显像仪测量了３６名航空航天风洞科研、试验人员（下称参试人员）上班前和下班后的左室功能，结果显示上班接触９１．５～１０１．５ｄＢ（Ａ）噪声后，左室ＳＶ、ＥＦ、Ｆｓ、ＭＶＣＦ、ＰＥ、ＳＥ、ＥＡＣ降低，ＳＡ、ＰＡ／ＰＥ增高，提示强风洞噪声对参试人员的左室功能有一定影响。A two-dimentional color doppler ultrasonic imaging instrument was used to detect the left ventricular function in 36 wind tunnel technicians before and after their work in the wind tunnel.The results showed that under the noise between 91.5 and 101.5 dB(A)inside the wind tunnel SV,EF,Fs, MVCF,PE,SE and EAC decreased while SA,PA/ PE increased.It indicates that high level wind tunnel noise has certain harmful effect on the left ventricular function of wind tunnel technicians.
