Shapton
is involved in design and experimental modal analysis of dynamic
structures. Recently, this has been combined with noise control
techniques to study vehicle noise, vibration, and harshness. Noise
path analysis techniques are applied to track the path that vibration
energy travels through a structure to attenuate, interrupt, and
control the resulting sound or vibration. Study of the sound quality
may indicate what properties of the sound are most objectionable
or desirable so that the spectrum may be shaped to optimize the
selection of alternative sound or vibration treatments.
