{"abstract":"The FAA is releasing a summary to the public of the research programs it sponsors on civil aircraft noise that could potentially inform future aircraft noise policy. The FAA invites public comment on the scope and applicability of these research initiatives to address aircraft noise. The FAA will not make any determinations based on the findings of these research programs for the FAA's noise policies, including any potential revised use of the Day-Night Average Sound Level (DNL) noise metric, until it has carefully considered public and other stakeholder input along with any additional research needed to improve the understanding of the effects of aircraft noise exposure on communities.","action":"Notice of research programs and request for comments.","agencies":[{"raw_name":"DEPARTMENT OF TRANSPORTATION","name":"Transportation Department","id":492,"url":"https://www.federalregister.gov/agencies/transportation-department","json_url":"https://www.federalregister.gov/api/v1/agencies/492","parent_id":null,"slug":"transportation-department"},{"raw_name":"Federal Aviation Administration","name":"Federal Aviation Administration","id":159,"url":"https://www.federalregister.gov/agencies/federal-aviation-administration","json_url":"https://www.federalregister.gov/api/v1/agencies/159","parent_id":492,"slug":"federal-aviation-administration"}],"body_html_url":"https://www.federalregister.gov/documents/full_text/html/2021/01/13/2021-00564.html","cfr_references":[],"citation":"86 FR 2722","comment_url":null,"comments_close_on":"2021-03-15","correction_of":null,"corrections":[],"dates":"Comments on this notice must identify the docket number and be received on or before March 15, 2021.","disposition_notes":null,"docket_ids":["Docket No. FAA-2021-0037"],"dockets":[{"supporting_documents":[],"agency_name":"FAA","documents":[{"comment_count":4159,"comment_start_date":"2021-01-13","updated_at":"2023-10-25T01:01:02.214-04:00","comment_url":"https://www.regulations.gov/commenton/FAA-2021-0037-0001","allow_late_comments":null,"id":"FAA-2021-0037-0001","comment_end_date":"2021-04-15","regulations_dot_gov_open_for_comment":false}],"supporting_documents_count":0,"id":"FAA-2021-0037","title":"Overview of FAA Aircraft Noise Policy and Research Efforts: Request for Input on Research Activities to Inform Aircraft Noise Policy"}],"document_number":"2021-00564","effective_on":null,"end_page":2728,"executive_order_notes":null,"executive_order_number":null,"explanation":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2021/01/13/2021-00564.xml","html_url":"https://www.federalregister.gov/documents/2021/01/13/2021-00564/overview-of-faa-aircraft-noise-policy-and-research-efforts-request-for-input-on-research-activities","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2021-00564?publication_date=2021-01-13","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2021-01-13/2021-00564/mods.xml","not_received_for_publication":null,"page_length":7,"page_views":{"count":18019,"last_updated":"2026-04-04 20:15:04 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2021-01-13/pdf/2021-00564.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2021-00564.pdf?1610459148","publication_date":"2021-01-13","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2021/01/13/2021-00564.txt","regulation_id_number_info":{},"regulation_id_numbers":[],"regulations_dot_gov_info":{"supporting_documents":[],"comments_count":4159,"agency_id":"FAA","comments_url":"https://www.regulations.gov/docketBrowser?rpp=50&so=DESC&sb=postedDate&po=0&dct=PS&D=FAA-2021-0037","supporting_documents_count":0,"docket_id":"FAA-2021-0037","document_id":"FAA-2021-0037-0001","regulation_id_number":null,"title":"Overview of FAA Aircraft Noise Policy and Research Efforts: Request for Input on Research Activities to Inform Aircraft Noise Policy","checked_regulationsdotgov_at":"2023-10-26T01:00:07Z"},"regulations_dot_gov_url":null,"significant":null,"signing_date":null,"start_page":2722,"subtype":null,"title":"Overview of FAA Aircraft Noise Policy and Research Efforts: Request for Input on Research Activities To Inform Aircraft Noise Policy","toc_doc":"Research Activities to Inform Aircraft Noise Policy","toc_subject":"Overview of FAA Aircraft Noise Policy and Research Efforts:\n","topics":[],"type":"Notice","volume":86}
