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.”

Where, Why and How to Use SoundEar3-300


The SoundEar3-300 can be used when you need to control noise at a hospital. It is most often used in:

  • Patient rooms
  • Recovery rooms
  • Operation theatres
  • Intensive Care Units
  • Neonatal Care


Noise in hospitals is an issue for both patients and staff. Reducing noise levels by just a few decibels can have a tremendous effect.

The SoundEar3-300 features that are most often highlighted by our customers are:

  • Visualizes noise in the patient rooms, making everyone aware that they need to keep the volume down
  • Receiving automated noise reports before or after a shift, directly in your inbox
  • Ability to compare and analyze noise levels over time in the software
  • Monitoring noise levels from multiple patient rooms at once


  1. To get started using your SoundEar3-300, connect it to a PC running the SoundEar Software and use the menu ‘Define Settings’ to set when you want the ear to turn red.
  2. Next, find a visible spot to mount it on the wall. Avoid placing it close to any sound absorbent materials such as soft fabrics or close to any noisy machinery, because it can affect the noise measurements.
  3. Start using the SoundEar Software to get insights into your noise levels.
