Comparing Noise Levels over Time:

“We are comparing the noise levels of rooms with the ear showing when there is too much noise [using SoundEar3-300] to the noise levels of rooms without the ear [using SoundEar3-320]. We can do this using the software, in which we can track noise levels over time for all the rooms in the NICU.”

Neonatal Intensive Care Unit / Rigshospitalet (National Hospital, Denmark)

Integrating with Building Management System:

“We use SoundEar3-320 to detect when noise levels are low (<30 dB), meaning that nobody is in the room. This information is sent via an analogue signal to our building management system, which then turns of the lights in the room, saving power.”

Søren Peglau / DR Koncerthuset (Danish Concert Hall)

SoundEar3-320: Simplify the process of measuring and documenting your noise levels

Make sure you are always updated on your noise levels, and rest assured that you have documentation for your noise levels.

What we like about SoundEar3-320:

  • Makes it easy to measure and monitor noise. Anyone can do it. No engineering background needed.
  • There is plenty of interesting noise data to dig into if you do happen to have a background in engineering or acoustics.
  • It gives you a simple and efficient way of managing and documenting noise levels
    • You can use the software to monitor noise levels 24/7 and in real-time
    • Or use it to analyze and compare noise levels – are there certain days or hours during the day with high noise activity?
    • You always have proper documentation for your noise levels with precision measurements.
    • Set up Email alerts if you want to be able to react instantly to critical noise levels
    • OUR PERSONAL FAVOURITE: Automated noise reports. You can schedule one or more noise reports to be sent directly to your inbox (or anyone else who needs to know) once a week or once a day, depending on your needs (requires automation add-on).

Where, Why and How to Use SoundEar3-320


Anywhere you need to know the actual noise levels.

SoundEar3-320 is used when it is important to know how much noise there is, and be able to analyze, compare and document those noise levels.

Examples of where SoundEar3-320 is being used:

  • Industrial sites
  • Hospitals
  • Bars, recording studios and concert halls

Examples of what our customers use it for:

  • Machine Maintenance: being alerted of machine malfunctions through fluctuations in sound pressure levels
  • Quality Control: finding the optimal level of sound for work requiring high levels of precision and concentration
  • Noise Comparison: Performing baseline measurements to compare noise levels before a noise-related intervention to those after the intervention


Because it makes your life easier.

You probably already know why you should measure noise and why noise is an issue (otherwise, take a look at our blog on noise).

Why you should use SoundEar3-320 for that? Being able to monitor your own noise levels and easily provide documentation for them, is what most of our customers would tell you.

  • Being able to Monitor Noise Levels 24/7 in the software makes it easy to get an overview of the noise situation
  • Monitoring Noise Levels from multiple locations at once (requires automation add-on)
  • Receiving email alerts when noise reaches a critical level means that you can act instantly to reduce critical noise levels.
  • Receiving automated noise reports (requires automation add-on), directly in your inbox is very convenient. It means that you are always updated on the latest noise developments.
  • The ability to compare and analyze noise levels over time and across locations in the software is practical when you need to dig a little deeper into a specific noise situation.


It really is quite simple. Just follow these 5 steps

  1. Connect the SoundEar3-320 to a PC running the SoundEar Software (it is very easy to use and we will guide you through it if you have any doubts) and make your settings such as naming the sound level meter and setting up email alerts for critical noise levels.
  2. Find the ideal location for your noise monitoring device. It is important not to place the device close to any sound absorbing materials, such as curtains or next to any noisy machinery, because that will skew the noise measurements.
  3. Connect the device to power and it will start measuring your noise levels.
  4. View your noise measurements in one of two ways:
    1. Download the noise measurements manually using a USB and open them in the SoundEar Software
    2. Have the SoundEar3-320 send noise measurements automatically to the SoundEar Software (via radio signal, Wi-Fi or LAN –  see automation add-on)
  5. Use the SoundEar Software to get insights into your noise levels and to provide documentation.
