Rion offer a wide range of really cost-effective solutions for aircraft noise. They are a viable alternative to aircraft noise monitors which are expensive both to install and maintain. You could have an easy to use long-term noise logger for as little as around £2500. For a further £1500 or so you could remotely control and download the noise logger.
Logging aircraft noise events does not have to be complicated and expensive. Some airports have found themselves unwittingly legally committed to the installation of an integrated noise and track monitoring system (NTM). The implementation, operation and maintenance of NTMs 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. Its 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 NTM 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.
