Frequently Asked Questions
- How loud is the Sonic Bomb alarm?
- Adjustable up to 113 dB, paired with an under-pillow bed shaker and a bright pulsing strobe. That combination is built to wake profoundly deaf sleepers and very heavy sleepers — it is deliberately more than a normal alarm.
- Is it too jarring for everyday use?
- It can be. The strobe and full-volume alarm are startling, and most people need to spend a few mornings tuning volume, shaker placement and the 5-level display dimmer to something tolerable. Expect to adjust it rather than to like it out of the box.
- Will it still work if the power goes out?
- Yes — a 9V battery backup keeps the alarm running through a power loss, which is the difference between a missed medication dose or appointment and a normal morning.
- Is the display easy to read?
- It uses large red LED digits with a 5-level dimmer, so it reads clearly across a room and can be dimmed at night. It is a basic look with no smart features, which is part of why it is inexpensive.
