Clicking the play button below will produce a tone that is generally only heard by people under the age of 25. It has been used as a deterrent device to keep teenagers from loitering in malls and shops, and sounds similar to a buzzing mosquito. The elderly and people with hearing damage often cannot hear the sound.
i am over 25 but my ears don't feel like they are. still, i failed this 'test'. can any young 'uns reading this blog confirm whether clicking the button actually produces any sound? i feel like i've been had.
