MICROPHONE IN SITU CALIBRATION THROUGH COMPARISON METHOD USING MLS TECHNIQUE

|
Summary :
|
|
ABSTRACT: THE MICROPHONE CALIBRATION THROUGH COMPARISON METHOD USING MLS TECHNIQUE IS INVESTIGATED. THE OBJECTIVE CONSISTS IN DEVELOPING A PROCEEDING TO PERFORM FREE-FIELD MICROPHONE CALIBRATION WITHOUT THE NEED OF AN ANECHOIC CHAMBER NORMALLY USED IN THIS TYPE OF CALIBRATION. THIS CAN REDUCE THE INVESTMENTS IN LABORATORY FACILITIES OF ABOUT US$ 300.000, MAKING EASIER TO ACCREDITATE SECONDARY LABORATORIES FOR THE BRAZILIAN CALIBRATION NETWORK. A ? MICROPHONE CALIBRATION WAS PERFORMED WITH THE PROPOSED METHOD AND THE RESULTS HAVE SHOWN A GOOD APPROXIMATION TO THE TRADITIONAL METHOD.
