1. A method, comprising:
receiving an acoustic input at a microphone of a hearing device;
receiving a wireless signal over a wireless link from an assistive listening device (ALD) at an antenna of the hearing device, the wireless signal including digital audio information;
comparing the acoustic input to the digital audio information using a processor of the hearing device; and
upon determining that the acoustic input and the digital audio information are correlated at a threshold level, using the processor to authenticate the ALD allowing the processor or the ALD to distribute an encryption key over the wireless link to secure the wireless link.
