Rion and ANV Measurement Systems offer a wide range of really cost-effective solutions for aircraft noise. They are a viable alternative to complex Integrated Noise and Track Monitoring (INTM) systems which rely on integration of the noise monitors with the airport's radar and/or information systems. It can take many months or even years to get to the point where INTMs start producing useful data and their implementation can be time-consuming, complex and extremely expensive.
Rion have a unique alternative system which identifies and classifies aircraft noise, automatically distinguishing it from extraneous noise sources. It’s a single, integrated system which has evolved through many years experience of airport noise monitoring. Purchase and maintenance costs are a fraction of those for an INTM system with traditional airport noise monitors.
The Rion NA-37B uses directional microphones and powerful cross-correlation techniques to log aircraft noise events, even automatically detecting whether the aircraft is taking off, landing or just flying past the measurement position by tracking its trajectory. An SSR radar receiver option can add additional certainty to the aircraft noise event recognition.
The NA-37B is supported by powerful software which can be used to control many instruments (at many different airports or all at the same airport). The software can automatically download the instruments and the noise events are automatically categorised. Weekly, daily, monthly and annual reports are all easily generated within the software. You can view (and hear if you have the audio recording option installed) each noise event individually if you have an event that needs further investigation.
At significantly lower cost again, you could simply install a Live Leq system. This would provide you with continuous real-time noise levels on a secure website with the ability to set alarms, alerts and trigger levels above which audio clips would be sent to the LivEnviro server for subsequent review.
If you don't need the monitoring data in real time, then deploying a Long-Term Monitor without web access can be done at extremely low cost. And the data from ANV Measurement Systems/Rion monitors can be imported directly into a spreadsheet or reveiewed very effeciently using Rion's AS-60 software.
