120dB@12VDC, it will less dB when at low voltage, but it's very loud@5VDC, and it's loud@3VDC

Please insert the plug into the panel and fix it by sticker paper or screw.You can also cut the wire and extend it.

At 120dbs, this siren will not only alert the neighbors of the intrusion, but scare away the burglar right out of your house!
