Improved Acoustic Power Estimates of Sound Sources in Semi-reverberant Enclosures Using Generalized Energy Density
This research is the continuation of work done at BYU to develop a practical method to experimentally estimate the sound power of an acoustic source in non-ideal acoustic spaces using generalized energy density. Previous sound power measurements are typically pressure-based measurements carried out in specialized rooms such as reverberation and anechoic chambers, which simulate diffuse-field and free-field conditions, respectively. These standardized measurements require costly facilities and cumbersome measurements. Most acoustic sources are used in non-ideal acoustic spaces where neither diffuse or free-field conditions are met. Thus, the acoustic pressure at any point is the sum of the direct and reverberant energies. Discussed will be the investigation and development of a method for estimating the sound power in these semi-reverberant rooms using generalized energy density.
