ABSTRACT:
An encrypted audio decryption system for decrypting encrypted audio sound. The system includes a hearing device and a key FOB. The hearing device is adapted to receive the encrypted audio sound, decrypt the encrypted audio sound, and transmit signals corresponding to the decrypted audio sound to a speaker of the hearing device. The key FOB is adapted to transmit a decryption key to the hearing device. The hearing device is adapted not to decrypt the encrypted audio sound without receipt of the decryption key, corresponding to the encrypted audio sound, from the key FOB.
