To transmit an actual sound (noise) when the noise level becomes higher than a regulation standard. In each noise detecting unit 1, the level of noise is measured through a microphone 5 and a noise meter 6 and input into a radio set 7. At the same time, an actual sound as the noise is input through a microphone 8 and a microphone amplifier 9 into a PHS 10. In a noise monitoring unit 2, a PC 14 communicates with the radio set 7 in each noise detecting unit 1 through a radio set 13 to input the noise level measured by each noise detecting unit 1. The PC 14 determines whether or not the noise level is higher than a regulation standard. If the noise level is higher than the regulation standard, the PC 14 requests a PHS 15 to call the PHS 10 in the specified noise detecting unit 1 to establish the communication between the PHS 15 and the PHS 10. At this time, a maintenance worker 4 can hear the actual sound from the PHS 15. Further, the actual sound is recorded by an MD recorder 16.
