dB is the abbreviation for decibel, a unit of loudness. The human pain threshold, from which the first hearing damage can occur, is around 120 dB - that's how loud e.g. B. a jackhammer.

Further examples:

• Whisper: 40dB
• TV at room volume or a normal conversation: 65 dB
• Main road: 85 dB
• Chainsaw: 110 dB
• China firecracker: 120 dB (pain limit)

For comparison: The essentials alarm siren , which you can get in our shop, reaches a volume of 95 dB (from a distance of 1 m). This means for you: The alarm tone cannot be overheard - but your hearing cannot be damaged if you keep the above-mentioned distance.
