ABSTRACT
This device aids deaf individuals who have difficulties in recognizing auditory alarms such as fire alarms, car honks, doorbells, and telephone calls. This portable device detects sound and re-alarms the user with a visual signal. LEDs on the board light up towards the direction of the sound. The color of the lighted LEDs represents the intensity of the sound.
