360° Sound Localization Support System for Deaf and Hard-of-Hearing People Using Smartglasses Equipped with Two Microphone

Deaf and hard-of-hearing (DHH) people have difficulty getting information. As a result, they are unable to notice emergency warning sounds such as ambulance sirens or car horns, and it therefore takes them longer to avoid danger. In this paper, we propose a system that can calculate the direction of a 360° sound source using two microphones. The effectiveness of this system is demonstrated by configuring a system that obtains the direction of the sound source using the sound size relationship and the time difference between the two microphones installed on the smartglasses, and displaying the direction calculation results on the lens. We discuss the proposed method and our validation of the calculations of the direction of a sound source.
