New Auditory Damage Risk Criteria and Standard for Impulse Noise
Abstract
This paper discusses the Auditory Risk Criteria as currently being proposed in a draft ANSI Standard. The criteria include two general prediction methods for estimating the hazard. One method, called the survey method, uses the A-weighted energy under a hearing protector to estimate the amount of hearing loss likely to be found for an exposed population. The second method, called a computer modeling method, provides an assessment for each individual waveform of an exposed population. The standard will provide the necessary software for this model. The standard will not provide specific criteria while wearing hearing protection, but instead will provide suggested validation procedures to insure that a specific program in which hearing protection is used actually is preventing hearing loss, either temporary or permanent. Criteria for identifying acoustic trauma and excessive fetal impulse noise will also be included.
