The Story: Born from Love for a Deaf Grandmother

Sonic Alert was founded in 1972 by Adam Kollin — for his deaf grandmother who couldn't hear conventional alarm clocks. What started as a personal project became the world's leading brand for vibrating alarm clocks and alerting systems for the hearing impaired. The Sonic Bomb is their flagship: over 50 years of expertise packed into one compact, reliable device.

Tips & Tricks for Best Results

• Place the bed shaker under the mattress — not under the pillow! Under the mattress, the vibration feels stronger and more evenly distributed.
• Use vibration-only mode for shared rooms — wakes only you while your partner sleeps undisturbed.
• Start at lower volume and increase gradually — find your perfect wake-up level without startling yourself.
• Insert the 9V battery immediately — protects you from power outages. Nothing worse than a dead alarm clock after a storm.
• Use 24-hour format for shift work — prevents AM/PM confusion.
• Test your settings before bedtime — try all modes once so you know exactly what to expect.

Frequently Asked Questions (FAQ)

How loud is 113 decibels really?
113 dB is about as loud as a jet aircraft taking off — louder than a front-row rock concert (110 dB) and just below the pain threshold (120 dB). The volume is fully adjustable though, so you can start quiet.

Can I use it without sound?
Yes! In "Vibration + LED Flash" mode, the alarm is completely silent. The bed shaker and flashing LEDs wake you reliably — perfect for deaf users or when your partner needs to keep sleeping.

Does it work during power outages?
Yes. With a 9V battery inserted (not included), the alarm clock continues working without mains power. We recommend inserting the battery right away.

Is it suitable for deaf people?
Absolutely — that's exactly what it was designed for! Sonic Alert was founded in 1972 to help deaf people wake up independently. The 12V bed shaker and LED flashes work without any sound at all.

Can two people set different alarm times?
Yes! The Sonic Bomb features dual alarms. Both people can programme their own wake-up time — perfect for couples with different work schedules.
