What is the decibel level and range for audible devices set by UL Standard 464?
UL Standard 464 specifies a range of audible alarms for devices, typically requiring that the sound output be at least 85 decibels (dB) at a distance of 10 feet. The standard outlines a frequency range for alarms to be effective, generally between 1,000 Hz to 4,000 Hz, as sounds within this range are more easily perceived by the human ear. Compliance with these specifications ensures that alarms are loud enough to alert individuals in an emergency situation.
