Paper outlines the design and development of an Assistive Listening Device (ALD) that will allow cochlear implant and hearing aid users to control which home audio source they will hear using a graphic user interface (GUI) on a personal digital assistant (PDA). The solution uses currently available Pocket PCs and an embedded Linux platform to handle audio signal processing and wireless communications. The system will deliver the ability to easily and seamlessly switch between multiple audio signals such as TV and radio, music listening, and telephony, with optional voice command based control. The ALD system has 3 major components: an ALD for multiplexing audio source signals and transmitting them wirelessly, a PDA as a client for receiving audio signals from the ALD and transmitting user control signals back to the ALD, and a Bluetooth headset for the user to listen to up to 8 audio sources without the burden of a wired connection. The gumstix Verdex line of boards was used as the hardware development platform for the ALD. Directions for further development of the listening device are discussed.
