How can a fire alarm be adapted so that deaf people can be alerted?
Conventional smoke alarms work by emitting a loud noise when smoke is detected, providing the vital early warning of fire, and therefore aiding escape. People who are deaf or hard of hearing need additional ways of making them aware the alarm has been activated, including vibrating pads and flashing strobe lights.
How can a deaf person’s home by modified to alert the residents to certain things?
Experts recommend installing smoke alarms and carbon monoxide detectors in several parts of the home. Since most alarm systems are designed for a hearing population, deaf people may want to look into alternatives that flash lights or vibrate.
What are some alerting devices for deaf people?
Alerting devices
- Baby cry signaler: Alerts when baby sounds are detected.
- Carbon monoxide detector: Alerts if carbon monoxide exceeds safe levels.
- Doorbell signaler: Alerts when someone is at the door.
- Smoke alarm signaler: Alerts if the smoke alarm is activated.

Can fire alarms cause deafness?
In the United States, a typical fire alarm sounds off between the 65 decibel and 120 decibel range. According to the National Institute on Deafness and Other Communication Disorders (NIDCD), repeated exposure to sound at 85 decibels or above can be enough to cause hearing loss.
Can deaf people hear alarms?
Conclusion. Deaf people use alarm clocks just as people who can hear do. But instead of making a sound, they rely on their sense of sight and touch.
How does a deaf person know someone is at the door?
The vibration sensor is usually adjustable on a door knock alert system, so the level of vibration that triggers the alert is determined by the person using it. For someone who is not entirely deaf but can’t hear a regular doorbell, a radio doorbell might be the answer.
Why do fire alarms hurt my ears?
A fire alarm, if heard at above 85 dB, could cause NIHL, or noise induced hearing loss. NIHL is a permanent loss in hearing due to the destruction of the tiny hairs lining the ear canal.
What devices do deaf people use?
Deaf people either use a device called a TTY (Telephone Type Writer) or use their computer to make calls through the National Relay Service. There are also other services like the ACE Video Relay Service and telephones that use captioning technology called WebCapTel.
Do deaf people have alarm clocks?
A deaf alarm clock is an alarm clock that is usually hooked up to a louder alarm, a strobe light, or a vibrator. An alarm clock with a louder alarm will wake up a person with minimal hearing loss. When the alarm clock goes off, it is much louder than your average alarm clock, and most people with a small amount of hearing loss are able to hear it.
Do deaf people hear anything at all?
People who are fully deaf aren’t able to hear anything at all, but many hard of hearing individuals can hear some of what goes on around them but may have trouble making out words or identifying when someone is trying to get their attention.
What is the communication system for the Deaf?
A telecommunications device for the deaf (TDD) is a teleprinter, an electronic device for text communication over a telephone line, that is designed for use by persons with hearing or speech difficulties.
