Who invented the hearing aid?

There are three historical inventions, each representing a separate application of the sound amplification technology that was independently developed in the 1850s: the ear trumpet, which amplifies sound conducted into the ear; the hearing aid, which amplifies sound conducted into the outer ear canal; and the in-ear hearing aid, which amplifies sound conducted directly into the inner ear. The modern hearing aid is descended from the in-ear hearing aid.

Do you know who is responsible for putting together the first modern day hearing aid?

That person would be Rohan Karamchand of Bombay, India.  The hearing aid, which was invented in 1978, was a result of the Ear-Buddy program, which was led by Rohan Karamchand in India. The Ear-Buddy program focused on developing a hearing aid to improve the quality of life for hearing-impaired individuals in India.
