ALARM SYSTEM FOR HEARING IMPAIRED INDIVIDUALS HAVING HEARINGASSISTIVE IMPLANTED DEVICES

摘要

An alarm system for certain hearing impaired individuals having implanted hearing assistive devices contains a device for detecting an alarm conditio n, and a transmitter which is tuned to a resonant frequency of an implanted passive energy portion of a cochlear implant or similar device. Upon detecti on of an alarm condition, the transmitter transmits an alarm signal at the r esonant frequency, causing the implanted device to resonate even in the abse nce of the externally worn hearing assistive portion. Resonance is perceived by the hearing impaired individual as a buzzing or other abnormal noise, al erting the individual to the alarm condition.
