SOUND PRESSURE LEVEL FEEDBACK CONTROL

METHODS AND SYSTEMS ARE PROVIDED FOR PREDICTING INTERNAL SOUND PRESSURE WITHIN A FLOW PASSAGE, BY MEASURING A VIBRATION VELOCITY RESPONSE OF A WALL OF THE FLOW PASSAGE, FOR EXAMPLE, USING ACCELEROMETERS (28). A RADIATION MODEL MAY THEN BE USED FOR PREDICTING EXTERNALLY RADIATED SOUND PRESSURE TO PRO...

Zusammenfassung:	METHODS AND SYSTEMS ARE PROVIDED FOR PREDICTING INTERNAL SOUND PRESSURE WITHIN A FLOW PASSAGE, BY MEASURING A VIBRATION VELOCITY RESPONSE OF A WALL OF THE FLOW PASSAGE, FOR EXAMPLE, USING ACCELEROMETERS (28). A RADIATION MODEL MAY THEN BE USED FOR PREDICTING EXTERNALLY RADIATED SOUND PRESSURE TO PROVIDE FEEDBACK TO CONTROL A PROCESS CONTROL SYSTEM. METHODS AND SYSTEMS ARE ALSO PROVIDED FOR PREDICTING EXTERNALLY RADIATED SOUND PRESSURE BASED ON INTERNALLY-MOUNTED PRESSURE TRANSDUCER SENSOR DATA.
