NNR- Noise Nuisance Recording System

The unique benefit of the NNR system is that it offers 24/7 remote access with the equipment while installed in the complainant’s property. Connectivity with the NNR system is via any standard web browser on a PC, Smartphone or Tablet which means no proprietary or ‘IT approved software’ is required to take advantage of this valuable facility.  Note, the NNR system can of course also be used off-line as a standard noise nuisance recorder   

The key benefits of remote access to the installed equipment include:

• Reassurance anytime, day or night, that the NNR system is operating correctly
• Ability to correct instrument setup errors remotely
• Verifying that the complainant has successfully made a number of recordings
• Download and review noise measurements and recordings while the equipment is still installed at the complainant’s property
• Smart decision making on when the equipment can be retrieved and thereby optimising equipment deployment.   

Live access to the on-going noise survey from your smartphone or PC using a standard web browser.

The system when installed continually logs the prevailing noise levels and the complainant activates a sound recording using the hand switch when disturbed by a noise event. This ensures that the complainant is in full control of when sound recordings are made.

The hand switch can be used to trigger audio recordings of 30 seconds, 1 minute, 2 minutes or 5 minutes duration with a pre-trigger facility of between 5 seconds and 30 seconds which records sound up to 30 seconds before the button was pressed. The pre-trigger facility is important in recording door slams, shouting, cars revving and other short duration high level events.

The hand switch has four buttons which can be used to record different noise sources or to rank noise events in order of the degree of annoyance. Also, for simplicity of operation the hand switch can be configured to start and stop a recording without distinguishing which button was used.   

The all-important review and reporting of noise measurements and recordings is carried out using the Data Explorer PC software offering a quick and easy assessment of the noise levels during the replay of recordings or for comparison of nuisance levels with the normal background levels in the absence of noise events. 

This PC software also offers the inclusion of comments by the investigating officer relating to one or more noise events and the facility to share one or more sound recordings in an e-mail sent to colleagues, the complainant, the perpetrator of the noise or indeed any other third party.
