Optimal Haar Wavelet Decompositions on Spherical Sound Fields
2018
ICIC Express Letters
To represent the sound field of a sphere, optimal parameter values for a set of spherical Haar wavelets forming an orthogonal basis are investigated. The Haar wavelet basis is defined on a sphere, which is sampled using a triangular mesh. Results from numerical experiments yield optimal parameter values that minimize the distortion error of the nonlinear approximation for various sound fields generated using sinusoidal waves of different frequencies.
