Free Idea # 302 - Reverse hearing aid

Produce an anti-hearing aid that would function in the
opposite way to a traditional hearing aid. When turned up
sounds would be muted, allowing the user to reduce the
volume of, for example, an irate boss, an elderly relative's
television set or a next door neighbor's drum rehearsals.
