Sound Level Meters
NA-39A Environmental noise monitor
Features
The NA-39A is a monitoring sound level meter specialising in monitoring the noise of aircraft flying overhead.
The NA-39A can discriminate between airborne and ground sounds and the direction of arrival of the measured object using our unique technology, and in combination with secondary radar (SSR) information used in air traffic control, it can identify aircraft with high accuracy.
It also records the time of noise generation and location information using GPS.
The main unit is equipped with LAN and modem terminals, enabling data collection and monitoring systems to be built using internet and telephone lines.
