The anechoic chamber of NC state university locates in the High Bay building on the centennial campus. This anechoic chamber is a full anechoic chamber mimicking an infinite space by absorbing acoustic and electromagnetic waves, providing a perfect environment to test those waves without reflectivity affecting the measurements being taken. The noise level in the chamber is in the range of 15 to 18 decibels (the average conversation is 50 to 60 decibels). The chamber is equipped with a sound testing system that has up to four channels. A 2D scan stage is set up in the anechoic chamber which can map the acoustic pressure distribution over a plane that is about 1.5 m by 1.5 m. For any detailed information about the anechoic chamber, please contact Dr. Yun Jing (yjing2@ncsu.edu).
