Abstract
An acoustic camera for using a MEMS microphone array comprises: an acoustic sensor apparatus () comprising a print circuit board () on which the plural of MEMS microphone () are mounted, to send signals for the detected sound to a data collection unit (); a data collection unit () connected to the acoustic sensor apparatus (), which samples analog signals related to sound transmitted from the acoustic sensor apparatus () to transform into digital signals and transmit them to the central processing unit (); a central processing unit () connected to the data collection unit (), which calculates noise level based on digital signals related to sound transmitted from the data collection unit (); and a display unit () which is connected to the central processing unit (), which displays in color the noise level calculated at the central processing unit.
