  The wireless recorder for heart and lung sounds is intuitively convenient to the medical doctors and the patients for its portability which makes the auscultation be possible in a certain range. Such a recorder facilitates increased patient movement (postures and exercises) during diagnosis. Therefore, a wireless communication system for lung sound recording has been developed in this study. Two unidirectional microphones (SM35 and Beta 98H/C, Shure), a wireless body pack transmitter (PGXD1, Shure), and a wireless receiver (PGXD4, Shure) were used in our recording system. The detected sound was transmitted to a mixing console (MG06, Yamaha) for amplification. The system characteristics are as follows: (1) offers excellent low-frequency response, (2) has unidirectional microphone sensing, (3) blocks noise from the environment, (4) records sounds of moving and exercising people, and (5)..
