Our project tackled the issue of sound sensing regarding Deaf and hard of hearing individuals. In describing our device we want to avoid calling it a hearing aid, because it in no way aids in hearing in the conventional sense. Rather, it provides a nuance form of sound feedback through haptics via vibration motors which can be taken advantaged by both the hearing and deaf. The device, worn around the neck, is embedded with four microphone-vibration motors pairs distributed evenly around it's perimeter. Sound that is registered by the microphones triggers their respective vibration motor. The strength of the vibration is proportional to the amplitude of the registered sound. Essentially, the user can feel the intensity and directionality of incoming sound. To combat issue of ambient sound, the device samples and retains the amplitude of the previous ten seconds, averages the ten samples, and sets it as the threshold at which new incoming sound must register in order to trigger vibrations.
