Abstract/OtherAbstract:
|
An isolated building, a fundamental case of urban acoustics, has recently been the subject of an experimental effort to characterize the building's influence on propagating sound [Alberts and Noble, J. Acoust. Soc. Am. 121, 3064 (2007)]. As a precursor to modeling efforts involving finite-difference time-domain simulations, two common diffraction models, the frequency domain model of Pierce and Medwin's extension of Biot and Tolstoy's time-domain model, have been utilized to estimate the sound pressure at various locations in the building's acoustic shadow. The discussion will include the models used and comparisons between calculated and measured data, demonstrating reasonable agreement between measured and calculated spectra in limited cases at some frequencies. |
