Advanced Instrumentation for Sound Monitoring

This paper reviews analytical models and software for sound propagation modelling and prediction, including room acoustics and outdoor sound propagation, and current instrumentation for sound measurement. Based on the review of the state-of-the-art for acoustic modelling and sound measurement instrumentation, emerging challenges are discussed. Finally, the paper proposes new instrument development using 3D sound-field sensor arrays and 1D/2D acoustic sensor arrays incorporated with sensor networks for soundscape investigation and further applications.
