NA-37
Environmental Sound Monitor
The NA-37 is an automated aircraft noise monitoring system.
The system has a feature for reliable identification of aircraft noise, while its compact dimensions make it suitable also for mobile use.
Measurement is fully automatic and continuous 365-day all-weather operation is supported.
The system is designed to be utilized for long term aircraft noise monitoring.

The Rion NA-37 Environmental Sound Monitor is flexible enough to measure both
1) Aircraft Noise measurement under the flight course
i. Aircraft Noise Processing Program – NX37B
ii. Aircraft Noise Data Processing Application Software – AS-50PA1
2) Aircraft and Ground noise measurement in the vicinity of airport
i. Aircraft Noise Processing Program – NX-37C
ii. Aircraft Noise Data Processing Application Software – AS-50PA2
Four microphones allow measurement of elevation angle and azimuth angle. (Requires AN-37)
