Design of Alert App and related Device for Hearing Impaired Users in India and Afghanistan

Most of the sounds such as the ringing of the phone, crying of a baby, doorbell, fire alarm and others are vital for everybody in day-to-day life. People with hearing impairment have difficulties in recognition of these sounds. This paper discusses a prototype design of Alert Device and related mobile phone app for hearing impaired users in their home environment. The prototype related design of both Alert Device and Mobile Prototype is designed based on a detailed literature survey as well as mobile app review. The prototype device design includes several important features such as detection of doorbell, crying of a baby, fire alarm, motion detection alarm, phone ringing, self-training of sound, SOS / Panic button and sound log. This device provides alert information on the mobile phone, tablet or smartwatch. In the future, the proposed alert app and related device will be developed with a focus to make it suitable for countries in South Asia and whole of Asia.
