The human ear attenuates background noise over time, a process which can lead to a loss of noise level objectivity. As a result, noise levels tend to increase during the course of the day. By measuring and displaying actual noise levels on you ward, the Noise Display provides you with valuable feedback to help you recognize and control excessive levels of noise.

Excessive amounts of noise can cause unnecessary stress for your patients and reduce your ability to work efficiently². Studies have shown that this stress can have a very real effect on wellbeing^3,4. The brain spends a considerable amount of energy filtering out unwanted stimuli, which is why it’s easier for most people to concentrate and rest in a quiet environment⁵. Noise Display can help you put that energy to better use.

Noise Display shows you noise levels using a series of colored lights: Green means that noise levels are within acceptable limits, while yellow and red lights signify potentially harmful amounts of noise. This easily recognizable display provides objective information, indicating when caregivers need to reduce noise to appropriate levels.

Visitors will quickly recognize the Noise Display system as a significant effort on your part toward achieving the goal of total patient comfort and care. It’s an obvious sign that you are doing everything you can to make conditions as pleasant as possible for you, your patients and visitors.
