dB is the abbreviation for decibel, a unit of volume. The human pain threshold, at which hearing damage can begin, is around 120 dB—that's how loud a jackhammer is, for example.
Further examples:
- Whisper: 40 dB
- TV at room volume or a normal conversation: 65 dB
- Main road: 85 dB
- Chainsaw: 110 dB
- Chinese firecrackers: 120 dB (pain threshold)
For comparison: The The essentials alarm siren , which you can purchase from our shop, reaches a volume of 95 dB (from a distance of 1 meter). This means that the alarm sound is unmistakable—but your hearing won't be damaged if you maintain the above-mentioned distance.
