Sound measurement at a factory worksite-1
(neighborhood area)
<JIS Z 8731 "Description and measurement of
environmental noise" >
Please refer to also ISO 1996
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.
