Facilities
TNCC facilities include a 16 x 16 x 10 ft. anechoic chamber, numerous instruments for vibration and noise measurements, and NT and HP workstations. Various commercial acoustics and vibration codes are available as well as specialized programs developed in house.

Research Areas

Scaled Noise and Vibration Measurements
Near and Far Field Noise Predictions
Vibration and Noise Control
Effects of Noise /Vibration on Human and Endangered Species ( Bio-Acoustics)
Noise Source Characterization
Computational Methods in Noise Propagation: Coupled CFD based on Finite Element Methods/ Kirchhoff Integral Methods
Objectives
The goal of the center is to understand and suggest solutions for noise and vibration problems associated with transportation. Current research is primarily concerned with the generation, transmission, reception and effects of transportation noise from road vehicles to space launch vehicles. Recent and proposed projects include a study of possible adverse effects of noise on endangered wildlife species, a characterization of noise and vibration generation mechanisms of vehicles and improved computer models for noise and vibration transmission including advanced mitigation techniques such as design of vibration isolation systems.
