Asius Technologies Stephen Ambrose offered to let Brian Johnson try out his company's newly developed in-ear monitors to see whether they could alleviate the hearing problems that forced the AC/DC front man to give up touring. Johnson, who says his hearing was damaged by high decibel AC/DC concerts and repeated exposure to loud engines during car races, emerged from the try-out thinking he just might be able to resume live performances after all. A statement released by the the company quoted Johnson, stating, "'I was really moved and amazed to be able to hear music again like I haven't heard it for several years now. I can't wait for it to be miniaturized so I can use it in every situation from normal communication, going out to noisy restaurants, to performing live music on stage." According to the Asius Technologies web site, Ambrose created an in-ear monitor that became so popular amoung touring musiicians by modifying swimming ear plugs in 1965. A musician himself, he became interested in coming up with a device that would address hearing loss among people exposed to loud music. His solution was a so-called 'second eardrum' for the company's ADEL (Ambrose Diaphonic Ear Lens) that intercepts and reduces the harm causing pressure assoicated with loud sound before it can do damage to the wearer's own ear drums.
