What is the minimum sound level output of smoke detectors at ten feet?

The minimum sound level output of smoke detectors at ten feet is established to ensure that the alarm is sufficiently loud to alert individuals who may be sleeping or otherwise not aware of a fire situation. Smoke alarms are required to emit a sound level of at least 85 decibels at a distance of ten feet. This decibel level strikes a balance between being loud enough to wake someone from sleep and not being excessively loud, which could cause discomfort or hearing damage.

Detecting smoke and alerting occupants is crucial in giving them the opportunity to evacuate safely. The standards for sound output are typically outlined by safety organizations and regulatory bodies to ensure that smoke detectors effectively serve their purpose in protecting lives during a fire emergency.
