Description
先ず、校正作業を行う場合には、図2に示すように、ステップSP1において、音響校正器3をマイクロホンアレイ1中の一つのマイクロホンM1に装着する。ステップSP2において、音響校正器3から1kHz(周波数)・94dB(音圧)の音響信号(校正音)を継続的に(例えば、3秒間)出力させる。ステップSP3において、A/D変換器4がマイクロホンM1,M2,…,MNの出力信号をデジタル信号に変換する。
Claims (1)
- マイクロホンアレイを用いて騒音を測定する騒音測定装置において、前記マイクロホンアレイの各マイクロホンからの音響信号が校正音であるか又は環境音であるかを識別する識別手段と、この識別手段により音響信号が校正音であると識別されたマイクロホンに対する校正を自動的に行う校正手段を備え、前記識別手段は一定音圧の音響信号が所定時間以上入力されると校正音であると判定し、前記識別手段が前記マイクロホンアレイのいずれかのマイクロホンからの音響信号が校正音であると判定すると、自動的に測定モードから校正モードに切り換わることを特徴とする騒音測定装置。
