Recent reports have established that the ring of a cordless telephone is sufficient to produce hearing loss. In the present study, the intensity and frequency spectrum of the ring signal for three cordless telephones known to be involved in reported cases of acoustic trauma are presented. The potential hazard to hearing is reviewed, the implications for the pediatric community discussed, and the recommendation made that unmodified cordless telephones be kept out of the reach of children.
