Product Q&A
Q
The neighboring facility is very noisy. Can I use this instrument to measure values as evidence for a complaint?
A
No, because to determine whether a factory or facility is causing noise disturbance, what needs to be measured is the “equivalent continuous sound level Leq,” not the “instantaneous sound level dB.”
