People who are hearing impaired often rely on hearing assistance technology. This includes two different types of devices: assistive listening which helps with listening and alerting devices which signal the presence of a sound such as alarm clocks for the hearing impaired.
For the purpose of this article, we will cover alerting devices.
Alerting devices assist a hearing impaired person to a warning sound which is necessary for their safety (and others around them) or which can help them with daily tasks. They can alert the individual to the sound of a signal from a telephone, a door ringer, smoke and fire detectors and alarm clocks.
There are three types of signals:
Auditory-These devices have adjustments for the volume and the pitch of the ringers. For people with high frequency hearing loss, the pitch can play a key role in hearing and distinguishing sounds. The volume is measured in decibels, so if a person knows what their range of hearing is, they can purchase a clock with a certain decibel range.
Visual-A sequence of flashing lights can alert a person with hearing impairment to a sound by differentiating between a doorbell (it may have two flashes) and a smoke alarm (which may have three flashes) for example.
Vibrotactile-Just as the word implies, a vibration can be felt by the person to alert them of a sound. These devices can be used on the body or under a pillow or mattress to get a person's attention to a sound. This type of device would not interfere with a house mate as the feeling is only felt by the person in contact with the vibrating object (like a pillow).
Alarm clocks for the hearing impaired may utilize a combination of some or all of these techniques to awaken the individual.
There are a variety of alarm clock styles available. Some are battery operated and portable, such as traveling alarm clocks. Others are hard-wired with a battery backup, like many conventional clocks on the market and still others may be worn on the body.
There are also vibrating wristwatches that can pick up sounds and vibrate on the person's wrist.
A snooze button is also available on most of the alarm clocks.
When looking for an alarm clock for the hearing impaired, it may be prudent to find a combination unit that incorporates a number of alerting devices together in one unit. Although they can be somewhat pricey, the devices alleviate the frustration of having multiple units around the house. These combo-units can work in conjunction with each other to provide a comprehensive safety device.
Also, keep in mind that there are styles out there for preteens and teenagers that can be fun and reflect their personality. Specialized alarm clocks for the hearing impaired can help instill a sense of independence in children as they grow up with hearing impairment.
