Abstract
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. 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.
