Federal Noise Standards
EPA sets product noise standards. OSHA sets workplace limits. No federal residential noise law - states and cities regulate.
EPA Noise Control Act (42 USC 4901) sets emission standards for products (trucks, motorcycles, equipment). OSHA: 90dB 8-hour workplace limit. FAA: airport noise programs. FHWA: highway noise standards for federal projects. No federal law for residential/neighborhood noise - entirely state and local jurisdiction.
