WHAT IS TDD/TTY?
 |
A TTY-TeleType or TeleTyperwriter, is an electronic
device that permits people with hearing and/or speech
limitations to communicate over the standard telephone
lines without the aid of an interpreter.
TTY's are also referred to as TT and TDD. TDD stand
for Telecommuniaton Device for the Deaf.

Origins
A deaf man introduced an invention to help the deaf to
speak on the phone. The invention was an electronic device
called an acoustic coupler that enables typewritten communication
over the telephone through the use of a teletypewriter
(TTY). In 1982, there were over 150,000 TTY sets in the
U.S. Not only are they in deaf people's homes, but in
many public places, businesses, airline reservation desks,
police, fire departments, hospitals and schools. Because
of this invention, deaf people can now one step closer
towards equal enjoyment of the technological luxuries
and necessities of modern culture. |

Krown History
Krown Manufacturing was founded in 1995 by Barbara and
Sidney Ander. The Anders entrepreneurial spirit along
with their desire to form a company that offers products
and services for the hearing-impaired was the primary
motivation in starting the company. Since both of the
Anders are profoundly deaf, they are in a unique position
to analyze the equipment and decide which services are
necessary for each particular client. |
