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.
Long-term data storage to internal memory
Data transfer via LAN
Support for data copy to USB flash drives (option)
Support for using GPS (option) for automatic time correction and acquisition of position information useful for mobile use.
Real Sound recording program NX-37WR (factory option) allows sound recording in two format types:
- Compressed (for long term recording)
- PCM (for analysis)
Color LCD screen provides good outdoor visibility
Battery backup power supply ensures continued operation during a power failure
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)
