171st Meeting of the Acoustical Society of America

چکیده
Apparently on the basis of room modes being excited in residential dwellings one concept has been to ignore high quality field measurement recordings (Wave files) and use the narrow band (FFT) Leq results of a 10-minute sample to create, by superimposing a number of sine waves, a trapezoidal time signal as the source for subjective testing and restricting the bandwidth to only infrasound. Other testing has utilised full spectrum signals but has issues with providing an accurate signal due to the limitation of the speakers. An examination of both methods and the limitations of the results have been examined and will be discussed.

متن کاملCoherence length as a figure of merit in multireference near-field acoustical holography.
Multireference partial field decomposition (PFD) can be used to generate coherent holograms for near-field acoustical holography measurements. PFD is most successful when the reference array completely senses all independent subsources, but meeting this requirement is not straightforward when the number of subsources and their locations are ambiguous (such as in aeroacoustic sources). A figure ...
