Airport Environmental & Noise 

Research Co-Sponsored by: 

• FAA Office of Airports, Planning and Programming 

– Planning and Environmental Division (APP-400) 

• FAA Office of Environment and Energy 

– Noise Division (AEE-100) 

Airport Environmental Research Purpose: 

Explore ways to improve the performance of airports in reducing their 

environmental impacts while responding to community needs for 

transportation services. 

Noise Research Purpose: 

To gain a better understanding of how aviation noise is perceived by 

communities around airports. Research guides national aviation noise policy, 

assists in determinations of community noise impacts, land-use guidelines 

and sound insulation programs.

observe how our precision of exposure response function would be 

affected. 

• If traffic down 20%, minimally affected 

• If traffic down 40%, 50 more subjects 

• If traffic down 50%, 100 more subjects 

• If more than 50%, wait until traffic is back up 

• At this time, it is not anticipated the initial study design will need to

Noise Abatement Charting 

Approach & Methodology

• Analyzed database containing 488 airport noise abatement procedures 

• Developed evaluation criteria to evaluate each noise abatement procedure 

• Analyzed all noise abatement remarks according to the evaluation criteria: 

1. The number of locations within a resource that pilots need to reference. 

• Airport Remarks, Military Remarks, Special Notices (back matter) 

2. Consistency of language including nomenclature and taxonomy. 

• NS ABTMT usage 43% ; voluntary? 81% unclear ; time conditions 76% unclear 

3. Clarity issues that make it difficult for a pilot to follow the instructions or misinterpret 

what are the noise sensitive locations. 

• 36% of remarks had sufficient descriptions of noise sensitive area. 

4. Whether the information published in the Chart Supplement is complete or if a pilot 

needs to reference other sources of information to fully understand an airport’s noise 

abatement program. 47% incomplete

Results

March 2, 2021 Administration 
 

 

 

Neighborhood Environmental Survey 

Purpose and Motivation for Conducting the Survey 

The FAA recognizes that aircraft noise continues to be a challenge 

• As part of our longstanding noise research program to better understand the 

impacts of aircraft noise on human health and welfare, we decided that a new 

national survey should be conducted to gather data to improve our collective 

understanding of how communities are currently responding to aircraft noise 

• The Survey is the first noise annoyance survey conducted by a US federal 

agency since the Federal Interagency Committee on Noise (FICON) performed 

an in-depth US Government agency review of human annoyance to noise in 

1992 

• FAA’s goal for the Survey was to obtain updated information about the way 

people perceive aircraft noise 

17 Federal Aviation 

March 2, 2021 Administration 
 

 

 

 

Neighborhood Environmental Survey 

Overview 

Neighborhood Environmental Survey 

• The agency conducted a nationwide survey of over 10,000 people living near 20 

representative airports regarding annoyance related to aircraft noise 

• FAA conducted follow-up phone interviews with 2,000 of the respondents to obtain 

qualitative information regarding individual responses 

• The responses to the survey were used to develop a nationally-representative “doseresponse curve,” which is a tool that establishes the relationship between annoyance and 

noise exposure 

• Results 

– The survey results show a substantial increase in public annoyance to aircraft noise compared to 

the data that FAA and other agencies currently rely on to inform noise policy, which was acquired in 

the 1970s 

– While the results of the survey bring forward new data, they are consistent with the observed trend 

of increasing noise concerns, and consistent with the results of more recent surveys conducted 

outside the United States

Neighborhood Environmental Survey 

Methodology 

Survey Instruments: 

• A mail survey was issued to participants 

around 20 airports experiencing a range 

of DNL noise exposure from aircraft 

• Questionnaire used a five point scale of annoyance and top two levels (4 or 5 on the scale 

from 1 to 5) were combined to come up with number of people who are “highly annoyed” 

• Since aircraft noise was one of 13 environmental concerns listed, the recipient did not know 

this was in fact an airport community noise survey 

• A follow up phone survey was also issued to mail survey participants to gain further 

understanding why they were annoyed

• Range of Available Airports Curves 

The new Survey was designed to use a consistent approach across each airport community surveyed. This has allowed for an 

enhanced ability to provide additional statistical information about the new results, such as the 95% Confidence Limits and range of 

results from each of the 20 airports, as shown on the plot above. This was not possible with the older Schultz Curve. 

 

 

Neighborhood Environmental Survey 

Aircraft Noise Annoyance Results 

The NES results support an observed increase in Annoyance from Aircraft Noise: 

• The results show a substantial increase in annoyance for the population living in the vicinity of airports 

• The increase in annoyance is generally consistent across various levels of noise exposure

Neighborhood Environmental Survey 

What do the Results Mean? 

The results of the Neighborhood Environmental Survey show a substantial increase in the 

level of annoyance to aircraft noise relative to past surveys 

Multiple factors may be driving these changes and public input is requested to inform next steps 

Public and stakeholder feedback 

on these and other factors will 

be critical to informing FAA’s 

understanding of the Survey 

results 

Taken together with the rest of the 

FAA’s noise research program, 

FAA is seeking to establish a 

national dialogue on aircraft 

noise issues

23 Federal Aviation 

March 2, 2021 Administration 

Recent Progress & Moving Ahead 

FAA has made efforts to meaningfully engage communities on noise concerns 

and will continue to enhance these efforts 

• Hired community engagement officers across each FAA region to expand the 

reach of Regional Administrators into communities 

• Working with airports and their noise officers to address legacy community noise 

concerns 

• Working with roundtables across the country to continually provide information and 

expertise as they have asked for airspace changes 

• Working within our air traffic organization to review procedures for reducing noise 

across the country 

• Added research projects to our portfolio to study airspace management concepts 

to determine if there are options that are safe and may provide a net environmental 

benefit 

• Implemented our noise portal nationwide through our Regional Aircraft Noise and 

Community Involvement webpages 

23 
 

 

 

 

 

 

 

24 Federal Aviation 

March 2, 2021 Administration 

Looking Forward 

How will the FAA use the Findings from the Survey? 

• The Neighborhood Environmental Survey provides data that quantitatively shows 

that substantially more people are highly annoyed by aircraft noise exposure than 

in the past 

• The FAA will look at the NES findings alongside outputs from other noise research 

programs and inputs from public and stakeholder comment to inform future actions 

• The ongoing research to understand the potential impacts to sleep and 

cardiovascular health should be particularly insightful 

The results of the survey are an important element of a broader portfolio of 

research and community engagement to investigate and mitigate the impacts of 

aircraft noise 

• The FAA intends to continue reviewing these research findings in combination with 

public and stakeholder feedback to inform research and policy priorities 

24 
 

 

 

25 Federal Aviation 

March 2, 2021 Administration 

Next Steps 

Publishing the Federal Register Notice (Notice) is a key first step towards 

engaging in a conversation with aviation stakeholders about FAA noise policy 

• FAA is encouraging the public and other stakeholders to review the Notice and 

Survey report, and provide constructive comments 

• Please note that the Notice and the Survey report provide data that will be used 

in the upcoming discussion about policy, but is not policy in itself 

Timeline 

• 60 day comment period on the Federal Register Notice 

• Review public comments and identify general themes 

• FAA will concurrently identify next steps beyond the Notice and engage 

with stakeholders as we move forward 

• Keep the public and stakeholders up to date as we make progress
