Emergency Sound Safety Check
Can you actually hear your smoke alarm? Your CO detector? Let's find out — and if you can't, we'll show you what to do about it.
Test Your Emergency Alert Hearing
We'll play 6 common emergency sounds one at a time. For each one, tell us if you can hear it clearly. At the end, you'll get a personalized safety report with recommendations.
Turn your volume to a comfortable level. Use speakers or headphones — whichever you'd normally have on at home.

Emergency Alerts and Hearing Loss
Why Emergency Alarms Fail People with Hearing Loss
Most smoke alarms and CO detectors use high-frequency tones above 3000 Hz — and high-frequency hearing loss is the most common type. That means the very people who need alarms the most are the ones least likely to hear them. Studies show that standard 3100 Hz smoke alarms fail to wake up a significant percentage of people with even mild hearing loss.
Alternative Alert Systems for the Hard of Hearing
The good news: you have options. Strobe light alarms flash brightly when triggered. Bed shaker systems vibrate your pillow or mattress to wake you. Smart home devices send push notifications to your phone. Vibrating watches and wearables can alert you throughout the day. The best setup combines two or more of these so you are always covered.
Home Safety Checklist for Hearing Loss
Go room by room. Bedroom: bed shaker alarm and strobe smoke detector. Kitchen: vibrating timer and smart stove monitor. Living room: video doorbell and flashing alert system. Every floor: interconnected smoke and CO detectors with strobe. Bathroom: waterproof vibrating alert. Make sure your phone is set to vibrate for emergency alerts and that all notification sounds are enabled.
Questions & Answers
Most smoke alarms beep at around 3100 Hz — one of the first frequencies to fade with age-related hearing loss. Even mild high-frequency hearing loss can make these alarms inaudible, especially while sleeping. Low-frequency alarms (520 Hz) and strobe or bed-shaker systems are much more effective for people with hearing loss.
Look for smoke detectors designed with strobe lights, bed shakers, or low-frequency (520 Hz) tones. Brands like Kidde and Gentex make models specifically for the hard of hearing. Many fire departments will install them for free — call your local station to ask.
Yes. Bed shaker smoke alarm systems connect a vibrating pad to your smoke detector. When the alarm triggers, the pad vibrates under your pillow or mattress to wake you. These are considered the gold standard for nighttime safety for people who are hard of hearing or deaf.
Smart smoke detectors like Nest Protect and First Alert Onelink send push notifications to your phone when they detect smoke or CO. Some standalone listening devices (like the Samsung SmartThings) can detect any standard smoke alarm and send you an alert.
Traditional smoke alarms use a 3100 Hz (T-3 pattern) tone. Research has shown that a 520 Hz square wave alarm is far more effective at waking people with hearing loss. Some newer alarms now use this lower frequency, and NFPA codes are beginning to require it in certain settings.
Extremely dangerous. Carbon monoxide is colorless and odorless — your detector is your only line of defense. If you can not hear it, you need a CO detector with a strobe light or one connected to a smart home system that sends phone alerts. This is not something to delay on.
