Biographical/Historical notes: 

The Deafblind Department has developed a total communication educational approach. This approach includes sign and spoken language, written language, braille, pictures, objects, gestures and other low and high tech augmentative communications systems, such as hearing aids. Their staff specialties include audiologists, behavior consultation, health services, occupational therapy, sensory motor integration, social work, speech and language and school psychology. 

The earliest hearing aids were created in the 17th century with the Ear Trumpet, Speaking Tubes, and Ear Fans. Electronic hearing aids were developed in 1898 after the invention of the telephone. The first Vacuum Tube hearing aid was patented by a Naval Engineer Earl Hanson in 1920 and sold by Marconi in 1923. Transistors hearing aids, developed by 1945, were much lighter and cooler than the Vacuum Tube hearing aid. These hearing aids were replaced with the advancement the Digital Hearing Aid. This digital-based device morphed into the high speed digital array hearing in 1987, making way for the “All-Digital” hearing aid in 1995. Further Digital Hearing Aid advancements continue, reducing the size and increasing operation options for the user.
