The Vibration and Acoustics Laboratories (VAL) at Virginia Tech were formed in 1985 to carry out education, fundamental research and applications in acoustics and vibrations as well as support its use in industry. Presently, VAL is focusing on investigating and developing advanced methods for active noise and vibration control systems. Other research work focuses on active-passive methods of reducing noise radiated machinery and transmitted into aircraft interiors. VAL is a Virginia Tech Research Center. Some of the current Master and PhD students are working on noise reduction in incubators as well as ICP sensors that measure brain pressure. Measuring transmission loss and determining absorption coefficients through an impedance tube was also an experiment performed.
