Noise monitoring for communities

Whether you are in the city, suburb or at a weekend getaway location, noise is an important factor in determining your quality of life or the success of your business.  Many areas have local noise legislation that defines the noise limits that can be produced and experienced during the day or at night.  This noise may be generated by vehicle traffic, aircraft, industrial sites, construction projects, entertainment events, or many other activities.

Noise monitoring is a tool that is used to manage the noise sources and the relationships between businesses and the community residents.  By monitoring the noise with real-time alerts, countermeasures can be made quickly the community can observe the progress noise abatement project.

Larson Davis offers a family of noise monitoring systems with various power, communication, and sound recording options that can be implemented to suit the needs of any community or business.

Larson Davis permanent, portable, or attended monitoring systems have options that are critical for a successful community noise management plan:
  • Weather data acquisition (including wind speed, wind direction, temperature, humidity, and rain fall)
  • GPS positioning to log noise locations and aid in noise mapping of communities
  • Event detection to identify when a establish noise threshold has been exceeded
  • Sound Recording to determine the source of noise events thru listening to the files
  • Automatic storage of data to USB flashdrive
  • Web publishing, emails/SMS alerts, and remote communication
  • Complete set of metrics (including octave and third octave filters to 6.3 Hz, frequency weightings, time weightings, Ln percentiles, and community noise calculations: Lden & CNEL, and more)
  • Tonality metric for calculating annoyance of tones
Permanent monitoring systems can be used to acquire data 24/7 and make operational adjustments as needed based upon fluid regulatory requirements, community feedback, or local regulations. Our portable monitoring systems can be deployed rapidly for specific studies over shorter periods of time and can be easily moved from one data acquisition site to another. They come with weather resistant enclosures and outdoor microphone options. Our hand held sound level meters can be used for on-site evaluation and logging of noise levels.
