From NRA-ILA:

On October 28th, the National Hearing Conservation Association sent its new position paper on firearms suppressors to the American Suppressor Association. The paper, in short, recognizes the important role that firearm suppressors play in reducing hearing loss associated with firearms and endorses the Hearing Protection Act, which would eliminate the current antiquated and overly complicated process for acquiring suppressors and instead use the same instant background check system that is used for almost all firearms.
