Jabra Noise Guide is a portable device that monitors noise levels and makes people more aware of the impact noise has on their work. You can use it to identify especially noisy areas and encourage workers to reduce office noise. Get instant visual feedback when noise levels exceed a set limit. The Instant Feedback Technology will make the unit turn red, yellow, or green to make people aware of the current noise level. This encourages everyone to reduce the noise, creating a better working environment. Measure and record daily noise levels over a period of up to three months. This can help identify and track problem areas in the office. Download noise data to a PC or a USB stick and analyze it using special SoundEar3 software.
