Dr. 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.
