Buying Guide: How to Choose Personal Alarms

Personal Alarms: Ear-Splitting Safety

130 decibels is LOUD—louder than a chainsaw, a rock concert, a jet taking off nearby. It gets attention. Fast.

How Loud Is Loud?
120dB: Threshold of pain
- 130dB: Jet engine at 100 feet
- 140dB: Permanent hearing damage without protection

These alarms are designed to shock and disorient, attracting attention and often causing attackers to flee.

### When to Use
- Walking alone at night
- Parking garages
- Jogging/running
- Elevator encounters
- Hotel rooms (door alarm use)
- Medical emergencies (calling for help)

### Features to Consider
- Volume: 120dB minimum, 130dB+ preferred
- Activation: Pull-pin is fastest, button requires pressing
- Strobe light: Additional attention-getter
- Attachment: Key ring, clip, wrist strap
- Battery: Replaceable vs. rechargeable

### Training Required
Unlike pepper spray, practice matters less. But:
- Know how to activate without looking
- Test it once so you know the sound
- Replace batteries annually

Frequently Asked Questions About Personal Alarms

Can attackers just grab and silence it?

Modern alarms require reinserting the pin to stop—which takes time and fine motor control. Many attackers panic and flee when attention is drawn. The goal is creating chaos and distance.

Won't people ignore alarms like car alarms?

Personal alarms at 130dB from 2 feet away are impossible to ignore—they cause physical discomfort. Very different from a car alarm 50 feet away.

Are personal alarms legal everywhere?

Yes—unlike pepper spray or tasers, personal alarms are legal everywhere with no restrictions. Carry them anywhere, including planes (in checked luggage).
