的詳細介紹ND-10/普通聲級計ND10
ND10普通聲級計
一、概述
ND10型聲級測試儀是一種袖珍式的聲學(xué)測量儀器，用來測量噪聲的計權(quán)聲壓（簡稱聲級）。儀器使用穩(wěn)定度較高的測試電容傳聲器，具有A及C頻率計權(quán)特性，“快”和“慢”時間計權(quán)（電表阻尼）特性和保持大有效值指示功能。儀器性能符合國際電工委員會（IEC）651號聲級計標(biāo)準(zhǔn)中對作為一般用途的Ⅱ型聲級計的要求，也符合GB3785標(biāo)準(zhǔn)的要求。主要性能接近以往對精密聲級計所規(guī)定的要求。
ND10型聲級測試儀性能穩(wěn)定，使用簡單，價格低廉，攜帶方便，可以用于環(huán)境噪聲、機器噪聲、車輛噪聲、電機噪聲等測量，也可用于建筑聲學(xué)、電聲等測量。對于持續(xù)時間較短（不小于100毫秒）的噪聲及需要測量大有效值聲級的場合（如測量行駛中車輛的噪聲），ND10型聲級測試儀的“保持”功能將是非常有用的，它還能將測量結(jié)果在電表上保持住一分鐘以上。
