Effect of low frequency noise on the echocardiographic parameter E/A ratio
The hearing condition of the Taiwanese aerospace maintenance workers affected by the low frequency noise had not been reported. The purpose of this research is to clarify the maintenance workers′ health effect when exposed to low frequency and/or general noises and to understand the relationship bet...
