<jats:p>While this is not a traditional academic presentation, it is an informal and open discussion with the inventor of the In-Ear-Monitor (IEM), by an untrained acoustician Jerry Harvey, out of the request to save the hearing of legendary Rock Star Alex Van Halen. In 1995, Harvey began tinkering and looking for components to solve the problem; in Japan, he found tiny electrical components; and in the United States, he found a tiny speaker designed for a pacemaker. He created a tiny in-ear speaker system that connected to a small receiver on Alex's belt via thin cables. The receiver then picked up the wireless signal from Harvey's mixing board. The in-ear monitors had two small speakers to separate output volume into low and high frequencies for bass and treble, and they fit into shells that were impressions of Alex's ears. The IEMs also blocked out ambient noise, and according to Alex Van Halen, “It was like night and day.” Today IEMs are widely used by musicians, audio engineers, audiophiles, and television presenters in order to receive vocal instructions, from a producer that only the presenter hears. The IEM market is expected to reach close to $1 Billion by 2024.</jats:p>
