Soundcheck is a noise level indicator that helps you identify if the place you are in is too loud and indicates noise levels to show if it is safe up to highly dangerous. Only 1 touch is sufficiant to know  the noise level that you are exposed to. 

Noise levels from 55 dB to 105 dB are pointed out with 3 colourered LED’s. Because it is so compact, it is easy to carry with you and at least you have a warning instrument that indicates when you have to wear your hearing protection.
