Alerting Devices

Alerting Devices for DHH

Alerting devices are to assist the persons with hard of hearing and deaf. Alerting devices use a loud tone, flashing lights or vibrations to alert people with hearing loss to various environmental sounds. These devices may also be called signalers or notification devices. Most devices work by sending signals to receivers in your home or office. The receiver produces a visual alert (flashing light) or a vibrating alert. Some devices work with existing alarms and doorbells, so additional electrical wiring is not needed.

These devices use the sound and visual amplification or vibration techniques for alerting the individuals with hearing impairment. Deafness can cause problems with everyday living. The range of Alerting Devices may offer the solution - from a vibrating watch to give a tactile alert that a cake needs to be taken out of the oven, to being woken up if there is a fact 'solutions to improve the quality of life'. These special alerting devices are available to wake you, indicate a visitor at the door or warn you of an emergency. Learn about the types of alerting devices for people with hearing loss.

Let Me Hear Again

As the name suggests, Let Me Hear Again is an app that assists people with hearing impairment. Founded by 29-year-old Sharon Baisil, a doctor, the app provides an alternative to expensive tools in the market such as videophones and vibrating alarms.

Let Me Hear Again has features like Virtual Notes, which allows users to capture speech and long conversations in the form of words; Quake awake alarm that makes sounds above their hearing level coupled with vibration; and Guardian Angel, which keeps a watch on people and alerts them when in danger. The app was awarded the 'App of the Month’ by MIT App Inventor.

Alert Options

Visual - a flashing light

Alarm Clocks for the DHH

Hearing a standard alarm clock can be a challenge for people with hearing loss. Specially-designed alarm clocks for people who have hearing loss come in many forms, including those that have built-in strobe lights or bed-shakers and those that have an outlet where you can plug in a vibrating alert, or a lamp to wake you up each morning.

Baby cry signalers

Regular baby monitors often do not generate enough sound for people with hearing loss to determine if their babies are crying. But manufacturers now make transmitters and receivers specifically meant to detect a baby's crying and transmit it to a central alert system.

Doorbell Signalers

There are doorbell signalers which work with or without an existing doorbell to make sure you know when someone is at the door. There are also security signalers that alert you if a door or window is opened in your home. Door signalers can range from a simple flashing strobe light to a system connected to your phone or one with its very own receiver. There are some that you keep in a central location in your home and they alert you, through a message and/or a flashing light when you're receiving a phone call or someone is ringing the doorbell.

Weather Alerts

Sometimes, people with hearing loss do not know about a dangerous storm because they cannot hear the rumble of thunder or crack of lightning. Additionally, some people don't watch TV or listen to the radio. In these cases, weather alerts can give warning about impending storms or other disastrous weather situations on the horizon. A weather alert radio can be used by itself or with other alerting accessories, such as strobes or bed-shakers, depending on your needs and preferences.
