We helped the Environmental Health team to refine the use of our online sound level monitoring platform to give them exactly the functionality they needed. The team had previously deployed an EM2010 sound level monitor for a long term environmental noise complaint investigation, but had not used the more advanced features of the online analysis tools, such as flexible limit checks and SMS alerts.
The Council chose the EM2010 for its automation and ease of use. They deployed the sound level monitoring equipment at the boundary of the park in advance of the first concert of the summer series. Measurement and upload began automatically, so the team were able to set up and manage their monitoring project online before the concerts, instead of on site. The concerts ran across multiple days and weekends, but the licensing conditions were the same for each one. This made the limit checks and alerting requirements quite specific - compare the sound level for every 15 minute period between 6pm and 11pm to the planning conditions and send an SMS alert to the designated staff on duty at each concert.
Flexible Monitoring and Alert System
The EM2010 was set to record sound levels every 5 minutes, uploading all readings to our online database. The Council team set their contact numbers and email addresses for alerts through their secure account login and also specified sound level limit values and start and end times for checks.
But our advanced features were able to offer them a little bit more. We adjusted our standard hourly and daily limit checks to analyse each 15 minute segment, giving the Council up to the minute checks on potential sound level breaches. Any problems were automatically highlighted to the staff on duty at that monitoring location so they could liaise with the event organiser.
Once the limit checks and alerts were set up, they were set to only run on days when the concerts were happening, meaning as soon as the EM2010 was powered on, the entire measurement and analysis system started automatically. This allowed the Council staff to measure multiple boundary points with a team of just 2 people on site.
With just 3 limit alerts triggered over the summer series, the Council were able to actively manage the noise emissions, with the minimum of resources. The fully automated sound level measurement system even gave them a few minutes to enjoy the music.
