title: Acoustic trauma in a telephone operator.
abstract: This case report describes an incident where a telephone operator suffered acoustic trauma from a subscriber blowing a whistle down a telephone mouthpiece, the sound being transmitted into the ear of the operator. Evidence of hearing loss persisted for several months before complete recovery was achieved. Comparison is made with hearing loss associated with the use of cordless telephones.
