Ever have the problem with people being too damn loud for their own good but they are so oblivious to their annoying voice? It could be noisy children if you're a teacher or that one co-worker who just doesn't know how to talk on a normal level. Well now you can literally visualise just how loud people are being with this noise meter. The louder the noise, the higher the balls will bounce meaning you need to tame it down a bit. Best bit is it will tell you to be quiet, so we will 100% be using this in the office for that one dude.
