Patent number: 6804513Abstract: A noise monitor for transmitting an actual sound (noise) when the noise level becomes higher than a regulation standard. In each noise detecting unit, the level of noise is measured through a microphone and a noise meter and input into a radio set. At the same time, an actual sound as noise is input through a microphone and a microphone amplifier into a PHS. In a noise monitoring unit, a PC communicates with the radio set in each noise detecting unit through a radio set to input the noise level measured by each noise detecting unit. The PC 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 requests a PHS to call the PHS in the specified noise detecting unit to establish the communication between the PHS and the PHS. At this time, a maintenance worker can hear the actual sound from the PHS. Further, the actual sound is recorded by an MD recorder.Type: GrantFiled: December 20, 2001Date of Patent: October 12, 2004Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Tsunehiro Okuya, Eiji Fukuda, Hiroyuki Yamano
