Telephone Assistive Devices

What are telephone assistive devices?

Telephone assistive devices help you hear telephone conversations better. You may need a telephone assistive device if you find that it is hard to hear or you miss information when you are on the telephone.

What kinds of devices are available?

There are many different kinds of telephone assistive devices.

  • Controls on your telephone. Some telephones have volume and tone controls. Adjusting the volume can make the person who is speaking to you sound louder. Adjusting the tone may make the conversation clearer. Many telephones have built-in amplification. They may have other features such as an extra loud ring and a flashing light to alert you when the phone rings.
  • Telephone amplifiers. Portable snap-on telephone amplifiers can be used with just about any telephone. The amplifier is placed over the earpiece of the telephone to increase the volume. You may have to remove the amplifier when you finish using the phone so that you can hang up the phone properly. Some cordless phones have extra amplification built in. Some of them also have jacks that can be used with a hands-free accessory.
  • Telephone coil in hearing aids. A telephone coil is a small coil of wire in some hearing aids. The wire is activated by a switch. It allows the hearing aid to pick up a phone signal directly. The coil also prevents feedback and cuts out background noise when you make a phone call. Telephones that are designed to work with a hearing-aid telephone coil are called hearing aid compatible.
  • Hands-free attachments for cell phones. Some cell phones can cause interference with hearing aids. You can get hearing-aid-compatible, hands-free attachments. The attachments allow the cell phone to be used at some distance away from the hearing aid. This can reduce or eliminate interference.
  • TTY. A TTY (or TDD) is a device that allows you to type your part of a phone conversation. Someone who also has a TTY can then read what you type and type a reply. If someone calls you who does not have a TTY device, they can speak to a special relay operator who types (or relays) the information to your TTY. Your typed response is then read back to the caller. This service is available throughout the US by dialing a special 1-800 telephone number or by dialing 711.

The cost of telephone assistive devices ranges from nothing (for built-in volume controls) to several hundred dollars for TTYs.
