Development of devices for communication under the noise environment such as disaster scenes is an important matter. In this study, to obtain the basic data for the communication device, the system that was able to reproduce the noise environments was constructed, and the sound pressure in the external auditory meatus (EAM) of normal hearing subjects who were listening to music under the noise environment with earphones and portable music device was measured. The results suggest that the frequency characteristics of the noise entering into the EAM are different according the type of the earphone. Each subject controls the volume of the portable music device according to not only the clearness of the sound signal but also an upper level for each subject's ear when they listen to the music under the noise environment.
