Auditory Hazard Assessment Algorithm for Humans

<p>The Auditory Hazard Assessment Algorithm for Humans (AHAAH) is a mathematical model of the <a href="/facts/Human_auditory_system/fJYTKjje">human auditory system</a> that calculates the risk to <a href="/facts/Hearing/EPYrVkSx">human hearing</a> caused by exposure to <a href="/facts/Impulse_noise_(acoustics)/lXIFYE84">impulse sounds</a>, such as gunfire and airbag deployment. It was developed by the <a href="/facts/United_States_Army_Research_Laboratory/CULgwaW6">U.S. Army Research Laboratory (ARL)</a> to assess the effectiveness of <a href="/facts/Hearing_protection_device/otnkDUhz">hearing protection devices</a> and aid the design of machinery and weapons to make them safer for the user.
</p><p>In 2015, the AHAAH became one of the two metrics used by the <a href="/facts/United_States_Department_of_Defense/dWAvf7e3">U.S. Department of Defense</a> to approve the <a href="/facts/United_States_Military_Standard/Y7a53qCL">Military Standard (MIL-STD) 1474E</a> for regulating maximum noise level exposure from military systems. It is also used by the <a href="/facts/Society_of_Automotive_Engineers/cBS1MznQ">Society of Automotive Engineers</a> to calculate the hazard of airbag noise and by the <a href="/facts/Israel_Defense_Forces/9hPaqcAM">Israeli Defense Force</a> for impulse noise analysis.
