What The Noise Pollution Clearinghouse does

The Noise Pollution Clearinghouse (NPC) is a U.S.-based national nonprofit organization founded in 1996 and headquartered at P.O. Box 1137, Montpelier, Vermont. Its stated mission is to create more livable cities and more natural rural and wilderness areas by reducing noise at the source. The organization pursues this through five activities: raising awareness of noise pollution; creating, collecting, and distributing information and resources on noise pollution; strengthening laws and governmental efforts to control noise pollution; establishing networks among environmental, professional, medical, governmental, and activist groups; and assisting activists working against noise pollution.

NPC's product surface consists of free, publicly accessible online resource libraries distributed through nonoise.org. These include the NPC Online Library (academic articles from WHO, EPA, FAA, NIOSH and others), the NPC Law Library (covering 500+ community noise ordinances from federal, state, and municipal sources), the EPA Noise Library (989 indexed documents from the EPA's Office of Noise Abatement and Control), the Hearing Loss and Occupational Noise Library, the NPC Resource Library, periodic newsletters (The Quiet Zone), the NPC Toolbox (interactive tools such as a Noise Footprint Calculator and Loudness Thermometer), and a Quiet Products and Services Directory. The organization is also executing a multi-year effort to revise the EPA's 1974 Model Community Noise Ordinance.

NPC's revenue model is donation- and sponsorship-based rather than transactional. It accepts individual donations through Network for Good and receives corporate sponsorship from approximately 20+ acoustics-industry firms that underwrite specific libraries and conference programming. All resources are provided free of charge to the public. The organization has a very small operational footprint: only one named individual (Les Blomberg) is identified in the source material, and no headcount is disclosed. Customer/user segments include environmental and activist groups, governmental and regulatory bodies, medical and occupational health professionals, and educational institutions.

Recent moves6 records

Expansion highlights5 records

Emerging players

• Quiet Mark: UK-based certification program for low-noise products; comparable to NPC's Quiet Products and Services Directory, though operating under a certification model rather than informational listing.
• International Noise Awareness Day: Annual awareness campaign run by the Center for Hearing and Communication; overlaps with NPC's noise-awareness mission but focuses on a single event rather than ongoing resources.

Broad incumbents

• World Health Organization - Environmental Noise Guidelines: International public health body that has published influential environmental noise guidelines for Europe; NPC's library references WHO research, indicating overlap in evidence base and policy audience.
• Sierra Club: One of the largest U.S. environmental nonprofits; addresses pollution broadly, including some noise issues, but does not specialize in noise pollution like NPC.
• Natural Resources Defense Council (NRDC): Large, well-funded environmental advocacy nonprofit; comparable in mission structure (advocacy + research) but operates across all environmental issues including some noise-related work.

Direct peers

• Institute of Noise Control Engineering (INCE-USA): Professional organization focused on noise control engineering, with overlapping sponsor base and shared advocacy for noise regulation; serves as a peer in the noise-policy ecosystem.
• Acoustical Society of America: Professional society promoting acoustics knowledge, including noise control; NPC's leadership presents at ASA meetings and ASA sponsors NPC conferences, indicating overlap in audience and constituency.
• Hearing Loss Association of America: Consumer advocacy nonprofit for people with hearing loss; NPC maintains a dedicated Hearing Loss Library and shares advocacy interests around noise-induced hearing loss prevention.
• National Council of Acoustical Consultants (NCAC): International organization of acoustical consultants that actively supports NPC as a philanthropic partner; serves the same consulting community and shares NPC's noise-policy interests.
• Quiet Communities Inc. Nonprofit organization dedicated to reducing noise pollution through research, education, and community programs; the closest direct peer to NPC in mission and structure.
