New Audiometric and Noise Measurement Calculators on the NHCA websitePosted: June 10, 2022 
As a hearing conservation professional, you may be called upon to compute binaural impairment using the formula of the American Medical Association, or to determine if sound levels in a test booth or under noise-excluding earphones meet the Maximum Permissible Ambient Noise Levels to properly measure hearing thresholds. You may have gathered noise dose data for an extended work shift and needed to normalize it to eight hours. For these tasks and others, the NHCA website now provides nine Excel-based calculators to assist you. The calculators are downloadable and free for use at the “Resources” Tab. Look for the “Audiometric and Noise Measurement Calculators” page or go here. Please use these tools and spread the word that NHCA is making them available to all. If you are aware of other calculation tools that would be helpful in your work, please contact NHCA so we may consider adding this content to our website in the future. |
