Remote Noise Monitoring

Cloud-based noise monitoring for any indoor application

Quantum Indoor is a powerful noise monitoring solution with built-in cloud connectivity, perfectly suited for unattended indoor noise monitoring across a range of applications. Quantum Indoor can be used for: long-term occupational noise monitoring; identifying the source and type of noise that is occurring; and highlighting where noise control measures are required.

Quantum Indoor is the perfect complementary solution to any existing noise monitoring regime as it offers all the freedom and benefits that come with remote outdoor noise monitors, but specifically designed for an indoor application. Constantly capturing and storing noise data on the MyCirrus cloud platform for you to access whenever you need it. You can also set up comprehensive event-based triggers to capture audio recordings and send alerts to users, allowing you to react to and control noise events in real-time.

Quantum Indoor is available with flexible subscription plans, allowing you to increase the amount of data you can store as well as enhancing the functionality of your Quantum noise monitoring network.

  • Measures everything you need for comprehensive indoor noise measurements
  • Sends all that data it captures directly to Cirrus Research's own cloud platform, allowing you to view live noise measurement information wherever you are, whenever you need it
  • View and analyse historic data and create detailed reports, directly from the MyCirrus cloud platform
  • Class 2 to IEC 61672-1: 2013, with a Class 1 version available
  • Real-time notifications via text message and email, or through the dedicated MyCirrus smartphone mobile applications
