A way to address the lack of auditory awareness in those with a hearing impairment to display an accurate identification and location of siren sound sources.

To improve situations that would be dangerous for hearing-impaired individuals in outdoor environments, a computational algorithm for the device is as follows. The device must record sound and go through a matching computation and well as direction computation in order to inform the user of the siren type (firetruck, police, or ambulance) as well as where the sound is coming from.
