A Wireless Sound Alert and Person Identity Notification System for People with Hearing Disabilities

Over 10 % of the world’s population, 800 million people, are suffering from hearing loss, and if they were to be taken into account it would be the third largest nation in the world. Current production of hearing aids meets less than 10 % of global need.

REPORT


Abstract Over 10 % of the world’s population, 800 million people, are suffering from hearing loss, and if they were to be taken into account it would be the third largest nation in the world. Current production of hearing aids meets less than 10 % of global need. About one out of forty people have hearing aids in developing countries. Moving in traffic without anybody’s help and calling others who are not in distance reachable by hand is a major problem faced by hearing and speech impaired people. The aim of the paper is to enable the hearing and speech impaired people recognize the horn sound of vehicles and make their interaction easy with other people having similar disabilities. So, to address this problem there is a need for a device which can assist the hearing challenged people responding to important sounds. This paper proposes a sound alert system which can detect horn sound and gives an alert, and also it can help them in calling one another, when they are in indoor environment. The sound alert system works with the help of microphone, an analog circuit and a microcontroller unit in traffic mode, and on the other hand with the help of a wireless communication module in the interaction mode.

Interaction



1 Introduction The major problem faced by hearing impaired people is going into traffic without anybody’s help. This is because they cannot hear horn sounds. The person who whistles horn expects the other to move aside. As the hearing challenged person is not able to hear that sound, there is a chance for accidents. Also, the hearing impaired people cannot listen if someone is calling him from behind.

So, the hearing challenged people need a device which can help them to respond to different sounds as well as a call from others. This purpose can be served using a device with a microphone and XBee modules to help respond to different sounds especially in traffic and to interact easily with other hearing impaired people, respectively. The existing assistive devices for deaf are very less in number and they can help only those with less than 20 % hearing loss. In addition to this, most of them are very expensive. They are not available and affordable for the common man. As a result, most of the hearing challenged people from the developing countries are unable to get benefit out of any of these devices. The wristband that interprets sound for the deaf is a device which gives the pictorial depiction of wide variety of sounds like ringing of telephone, music, door bell, horn, etc. It also alerts deaf people in danger by vibrating and helps them view a pictorial depiction
