The C4230 cordless amplified telephone from Clarity, Chattanooga, Tenn, designed for people with moderate-to-severe hearing loss, has earned commendation from the Arthritis Foundation‘s Ease-of-Use program as a
user-friendly product for the 46 million people living with arthritis.
Designed by Clarity, a division of Plantronics, the product was recognized for its ergonomic handset design and large, east-to-operate buttons.
Inspired by an ice cream scooper, the handset’s concave earpiece creates an acoustic chamber that improves the quality of the sound, and the phone uses patented Digital Clarity Power to intelligently amplify incoming sound up to 50 decibels, making conversations louder, clearer, and easier to understand.
The device was evaluated at the Georgia Tech Research Institute, an independent lab that analyzes how accessible
products are for people with functional limitations due to the effects of arthritis.
The C4230 features dual amplified speakerphones in the handset and the base, along with a variable speed playback digital answering machine. This allows users to check messages through the portable handset or the
amplified speakerphone, and to slow down message recordings to make them easier to understand. Other features include adjustable volume, tone and balance, and visual and tactile ring indicators that help people with low vision.
Clarity provides amplified telephones, notification systems, assistive listening devices, and other communications devices for the hearing-loss and deaf markets.
