									                    Abstract
The objective of this project is to construct a multiple
audio device for the elderly. The device will be
designed to be a user-friendly, aesthetically
appealing, and inexpensive. The multiple audio
device is unique as it combines many of the current
technologies into a single product specifically
designed for the older generations. Current devices
are geared towards a younger audience and only
contain a single functionality. Ideally, the device
would be used on a daily basis with limitless future
add-on capabilities. As a design team, we offer our
constructed prototype and justification for our
design. The ultimate goal of this project is to
improve the quality of life for the older generations
by shaping modern technology to their needs.
