 Monitor traffic noise

Acoustics Measurement > Environmental noise
For road traffic noise monitoring, a microphone is positioned at a given point next to a highway or major road, and a sound level meter is used to record level fluctuations as well as actual sound at the site. With a constant monitoring system, interval measurement is also possible. Noise events are detected automatically and evaluated to determined whether they are aircraft noise.

 Monitor environmental noise

Acoustics Measurement > Environmental noise
Use the general-purpose sound level meter NL-42 or high-precision sound level meter NL-52 for monitoring environmental noise.

 We want to monitor aircraft noise

Acoustics Measurement > Environmental noise
For aircraft noise monitoring, a microphone is positioned in the vicinity of the airport or at a point in the flight path, and a sound level meter is used to record level fluctuations as well as actual sound at the site. In a constant monitoring system, noise events are detected automatically from level fluctuations and are evaluated to determine whether they are aircraft noise. A system for detecting ground-level sound events occurring at airports can also be configured.

 Monitor railway vehicle noise

Acoustics Measurement > Environmental noise
Use a sound level meter and environmental measurement data management software to measure sound events at a railway trunk line.

 Measure Shinkansen super express train noise

Acoustics Measurement > Environmental noise
Use a sound level meter and environmental measurement data management software to measure sound events at the Shinkansen line.

 Monitor noise emanating from a factory

Acoustics Measurement > Environmental noise
Use a sound level meter to monitor factory sounds at the boundary of the site.
