We have two noise warning signs for use in hospitals and neonatal units / NICU. The SoundEar and NoiseSign have similar functions, so the choice is often based on appearance and which style fits best into your hospital rooms and corridors.
The SoundEar is a wall mounted sign that lights up to indicate when the noise levels are too high for the patient, family, visitor and staffs satisfaction. The green lights are always lit, just as a reminder. When the levels get close to the limit the yellow lights come on. When the limit is exceeded the red lights come on.
The latest version of the popular SoundEar Noise Warning Sign. When the sound levels get high, first the yellow part lights up, followed by the red light when the noise limit is passed. This new version of the sign works in a similar way to the older SoundEar, but is in a cleaner, minimalist design.
The SoundEar 3 is visually very similar to the SoundEar 2, with the addition of a digital display to show the sound level in dB. However, it has more advanced settings with multiple trigger levels and the night mode for lower levels and lighting at night. This is a data logging sign that comes complete with software to download the results.
For low-key, long term noise monitoring, the SoundEar 3-320 can be mounted on the wall, where it can display the sound level on its digital display, or it can be set to show the time, temperature or nothing at all. It stores the sound levels for download to a computer or it can be linked to monitoring system via 4-20mA loop or DC 0-10V output.
Unnecessary noise is the most cruel abuse of care which can be inflicted on either the sick or the well.
Florence Nightingale, 1859.
These noise warning signs are in use in many hospitals around the world, particularly in the USA and the UK. As a result of very careful design, the message to anybody making noise is very clear. Mounted within wards, in corridors and around the nurses' station, they give a constant and clear reminder that the noise should be kept to a minimum.
