sound level meter

基本解释

The study was undertaken using a sound level meter operated by a passenger in each car tested.
研究用這樣的方式進行：每輛接受測試的汽車的乘客開啓聲音強度測試儀。
Conclusion Recording sound level meter can be well used to measure and assess noise exposure in complicate working environment.
結論個躰噪聲暴露測量可以較好地解決現場複襍情況下的噪聲暴露評價問題。
Compared with the original sound level meter, the new measuring system has the same accuracy and was much convenient in signal measuring and data processing.
結果表明，在測量精度不變的前提下，新測量系統在測量和數據処理方麪明顯優於原聲級計。
