Mining Noise Monitoring

Measure Decibel Level from Mining Operations

Mining environmental noise monitoringThe management of noise from mining operations is recognized as a fundamental responsibility of the mining industry. Implementing a noise management system that includes noise surveys, day and night noise mitigation, and some level of noise monitoring is a primary function that is required to meet environmental impact standards in most locations.

Some potential noise sources from a mining operation includes: vehicles such as scrapers, dozers, excavators, and trucks; fixed equipment such as conveyors and crushers; and blasting of rock and ore.

Larson Davis provides a complete suite of noise monitoring options that allows each operation to easily implement their own noise monitoring solution that meets their specific needs. By owning the noise monitoring plan and the data, a mining operation can be in full control of the Noise Management Plan and the interaction with the community and regulatory agencies. Each mine can develop practical mitigation solutions that are workable for the mining company and they can demonstrate that they effectively meet regulatory and community expectations. With Larson Davis monitoring solutions you can…

  • Survey your operations
  • Evaluate your compliance to regulations and standards
  • Evaluate your mitigation efforts
  • Continuously monitor your noise to confirm compliance
  • Receive “alerts” for implementing immediate countermeasures
  • Record sound file for noise source identification
  • Publish noise measurements and sounds to the web for remote viewing

Community noise complaints can lead to costly regulatory investigations and requirements for operational limitations and constraints. Larson Davis monitoring systems allow a mining operation to gather detailed data and sound recordings that can be used for addressing community concerns and perceptions. The data can be shared with communities and sound events can be listened to and correlated with complaints to identify sources. By proactively managing your community noise perception you can save costly delays and unnecessary countermeasures.

Mining Noise Monitoring

Larson Davis systems offer a complete set of metrics including octave filters (1/1 and 1/3), frequency weighting, time weighting, Ln percentiles, community day and night noise calculations (Lden and CNEL), and more.   Selecting a system that serves the needs of the project and the budget will include evaluating variables such things as:

  • Monitoring Duration
  • Power Requirements
  • Installation and Mounting
  • Portability and Deployment
  • Remote Communication
  • Web Publishing and Alert Notification
  • Sound File Recording
  • Data Analysis and Reporting
  • Open Architecture and Customization
  • 24-hr Technical Support


  • Stone Quarry Noise Monitoring
  • Equipment Noise Monitoring
  • Mining Noise Management
  • Blasting Noise Monitoring

Categories of Noise Monitoring Systems

  • SoundAdvisor™ for Permanent, Long-term Noise Monitoring: Model NMS045 delivers 24/7 connectivity, continuous power capabilities, and a rugged design to simplify your long-term testing. Encased in a fiberglass enclosure, NMS045 is mounted to a permanently placed pole. With easy installation and maintenance, AC or solar powered options, and email or text alerts of exceedances, Model NMS045 is an ideal permanent monitoring solution.
  • SoundAdvisor™ for Portable, Short-term Noise Monitoring: Model NMS044, similar to Model NMS045, is a completely wireless solution designed to run indefinitely on solar power, allowing you to take measurements and view them 24/7. A rugged case houses the system making it an ideal solution for remote noise monitoring. The Model NMS044 can be deployed rapidly and easily. As with NMS045, you can receive real-time alerts of exceedances.
  • Basic Portable Noise Monitoring: SoundExpert® Model LxT offers basic functionality for short-term monitoring. Deploy the system and operate on battery power for up to two weeks before retrieving and downloading measurement data. The system does not offer 24/7 access to measurements or real-time alerts.
  • Attended Noise Monitoring: For on-site assessments and evaluations of individual noise sources over a period of minutes or hours a sound level meter such as the SoundAdvisor™ Model 831C or   SoundExpert® LxT can be used via a tripod or hand held monitoring.
