sound A-1-2 Sound measurement at a factory worksite-1 (neighborhood area)

<JIS Z 8731 "Description and measurement of environmental noise" >

  • Separate the microphone from main unit of LA-1441A and set it at the boundary line between factory and private house which is required noise monitoring. Then place the main unit of LA-1441A in the working office away from the microphone max. 100m. (The microphone can be separated from the main unit of the LA-1441 max. 305m.) The continuous measurement function of LA-1441 enables monitoring the sound level by measuring the time-average sound level (equivalent continuous sound level, Leq) over again, for example in an hour.
  • The LA-1441A can store the measurement data in the internal memory and recall them. The stored measurement data can be transferred to the PC via USB or RS-232C interface.
  • Also, installing LA-0141 comparator output function (option) allows the LA-1441A to lighten the external alarm lamp when the sound level exceeds the setup value. Please feel free to contact your nearest distributors or send an email to us (overseas@ONO SOKKI.co.jp) for more details.
