Description
Third Ear for Deaf Person is an assistive alert system specially designed for hearing-impaired individuals. Built using an Nano, this smart device detects loud sounds (like clapping, honking, or shouting) and immediately alerts the user through vibration and flashing red LEDs. A green LED indicates that the system is powered and ready.
The system runs on a standard 9V non-rechargeable battery and includes an ON/OFF switch for manual control. It is fully assembled and tested, making it ideal for school and college science exhibitions, B.Tech mini projects, or awareness campaigns for inclusive innovation.
This project not only demonstrates how sound can be converted into haptic and visual feedback but also promotes the development of low-cost assistive technology for the deaf.
