The specific loudness or sound level emitted by the Apple AirTag 4 Pack can vary based on the distance from the AirTag and the surrounding environment. However, the AirTag is designed to emit a sound that is audible enough to help locate misplaced items nearby. When you trigger the sound through the Find My app on your iPhone or iPad, the AirTag emits a series of chirping sounds to assist in locating it.
Please note that the sound emitted by the AirTag is not intended to be excessively loud, as it is primarily meant to help you locate your belongings in close proximity. It is not designed to serve as a personal safety alarm or to alert others in a loud environment.
