Definition of Auditory Hazard Assessment Algorithm for Humans
The Auditory Hazard Assessment Algorithm for Humans (AHAAH) is a mathematical model of the human auditory system that calculates the risk to human hearing caused by exposure to impulse sounds, such as gunfire and airbag deployment. It was developed by the U.S. Army Research Laboratory (ARL) to assess the effectiveness of hearing protection devices and aid the design of machinery and weapons to make them safer for the user.
In 2015, the AHAAH became one of the two metrics used by the U.S. Department of Defense to approve the Military Standard (MIL-STD) 1474E for regulating maximum noise level exposure from military systems. It is also used by the Society of Automotive Engineers to calculate the hazard of airbag noise and by the Israeli Defense Force for impulse noise analysis.
