INTERESTS
Computer
Modeling
An
analysis of the effect of model detail level on
room acoustic simulations developed in computer
modeling programs.
Simple
3D geometry utilized in computer modeling
Classroom
Acoustics
A
review of the acoustical concerns of learning environments,
including a survey of local schools and an outreach
program designed to interest students in acoustics
and engineering.
Beneficial
sound reflections in a classroom setting

Coupled
Volumes
A
study of the acoustic fields generated in spaces
with two or more volumes connected by acoustically
transparent apertures.
|
Representative
sound decay profile from a coupled volume system
|
Acoustic
Scattering
An
investigation assessing the scattering characteristics
of 2-D surfaces exhibiting fractal geometries. The
2-D diffusor type is useful in spaces with high sound
pressure levels and low-frequency concerns, such as
those most often seen in the ubiquitous multipurpose
performing arts spaces being built in this time of
economic mindfulness.
