Hearing Protection Act

S 364, titled the "Hearing Protection Act" (though it regulates firearm silencers, not hearing protection), changes federal law to treat firearm silencers like firearms for tax and regulatory purposes. It imposes a 10% federal tax on silencers (similar to firearms), preempts state laws that tax or regulate silencers beyond federal rules, and requires the destruction of existing silencer registration records within one year. The bill clarifies definitions of "firearm silencer" in federal law and modifies licensing requirements for these devices. This directly affects silencer owners, manufacturers, and state governments that previously imposed additional restrictions or taxes.
