In order to investigate the subjective impression caused by various kinds of environmental sounds in residential buildings, a series of subjective tests were performed by laboratory experiment using a multi-channel recording/reproduction system. As the test sounds, road traffic noise, railway noise, air-conditioning system noise, rock music transmitted through a wall, structure-borne pump noise and floor impact sound were presented by single sound or by mixing two sounds to investigate the effect of the noises. As a result, it has been found that rock music and pump noise are much annoying/disturbing than road traffic noise and air-conditioning system noise even if they have the same A-weighted sound pressure level. Regarding the effect of complex noises, rock music and pump noise can be masked psycho-acoustically by air-conditioning system noise but railway noise and floor impact sound can not be masked by road traffic noise.
