No one knows when people first discovered that covering the ears with the flats of the hands or plugging up the ear canals with one's fingers was effective in reducing the level of unwanted sound - noise - but the basic tecnique has been in use for generations as the last line of defence against loud sound. Unfortunately, this level of technology precludes the use of most others. Hearing protectors, an obvious solution to the problem, are a form of noise control in that thye block the path of the noise from the source to the ear.
