We recently spotted this great sound level meter device in Ipswich hospital which helps staff and patients control sound on the ward. SoundEar® is a noise indicator that emits a visual alarm signal (see image) when a previously set noise level is surpassed in a room. If the sound level is acceptable, i.e. below the selected limit, the sound level meter illuminates the image of an ear in green. A yellow ear symbol indicates that the sound level is close to the limit value and when the sign turns red, the limit has been exceeded. A great device to help take immediate action without somebody having to ask people to be quiet thus removing any embarrassment from the complainer/noisy person.
