Helmholtz equation-least-squares method for reconstructing the acoustic pressure field
Zhaoxi Wang,Sean Wu +1 more
TL;DR: In this article, a method using spherical wave expansion theory to reconstruct acoustic pressure field from a vibrating object is developed, where the radiated acoustic pressures are obtained by means of an expansion of independent functions generated by the Gram-Schmidt orthonormalization with respect to the particular solutions to the Helmholtz equation on the vibrating surface under consideration.
Journal ArticleDOI
On reconstruction of acoustic pressure fields using the Helmholtz equation least squares method
TL;DR: The Helmholtz equation least-squares method is shown to be very effective in the low-to-mid frequency regime, and can potentially become a powerful noise diagnostic tool.
Journal ArticleDOI
Synthesis, formation and characterization of ZnTiO3 ceramics
TL;DR: In this paper, a powder of ZnO and TiO 2 in a molar ratio of 1:1 was mixed in a ball mill and then heated at temperatures from 700 to 1000°C for various time periods in air.
Journal ArticleDOI
Methods for reconstructing acoustic quantities based on acoustic pressure measurements
TL;DR: This paper presents an overview of the acoustic imaging methods developed over the past three decades that enable one to reconstruct all acoustic quantities based on the acoustic pressure measurements taken around a target source at close distances.
Journal ArticleDOI
Reconstructing interior acoustic pressure fields via Helmholtz equation least-squares method
Sean Wu,Jingyou Yu +1 more
TL;DR: In this paper, the authors extended the least square method to the reconstruction of acoustic pressure fields inside the cavity of a vibrating object, where the coefficients associated with these acoustic modes were determined by requiring the assumed-form solution to satisfy the pressure boundary condition at the measurement points.
