An anechoic chamber was constructed to make to condition of acoustic free field at the Department of Physics, Sung Kyun Kwan University. In this paper the criteria for the design and construction of the anechoic chamber are described. 48cm long wedges of density 15.3kg/㎥ glasswool attached to the 40×20×20㎤ base were used for the lining of anechoic chamber with the cutoff frequency of 125Hz. The interior space of the chamber is 3.56m long, 3.38m wide and 2.37m high.
