The Baltimore/Washington International Thurgood Marshall Airport (BWI Marshall Airport) is owned and operated by the Maryland Aviation Administration (MAA). As part of our continuing efforts to mitigate the effects of aircraft noise within areas surrounding BWI Marshall Airport, The MAA is pleased to announce the continuation of the voluntary Residential Sound Insulation Program (RSIP). The MAA has hired The Jones Payne Group, a nationally recognized expert in aviation noise mitigation to manage and implement the BWI Marshall Airport RSIP. The objective of the sound insulation program is to reduce the interior noise levels within eligible residential dwelling units to be compatible with airport operations. The Federal Aviation Administration (FAA) goals for the project are to achieve an interior noise level no greater than a Day Night Average Sound Level (DNL) 45 dB and a minimum 5 dB reduction by installing new acoustically rated windows, doors, ventilation, and other customized treatments approved by the FAA. 

Eligibility for the Residential Sound Insulation Program is determined first by evaluating the location of a home relative to noise contours on BWI’s most recent FAA-approved Noise Exposure Map (NEM). An exterior Day Night Average Sound Level greater than DNL 65 dB is what the FAA considers as the threshold for residential land use incompatibility around airports. Residential properties that fall entirely within the DNL 65 dB noise contour are potentially eligible for participation in the RSIP. To view the Noise Exposure Map, please click here.

Final determination of eligibility will made through acoustical testing on the property to ensure the home has an interior noise level equal or greater than DNL 45 dB.

In addition to being located within the FAA-approved noise exposure boundaries and having an interior noise level DNL 45 dB or greater, a home must also meet all the following criteria:

  • Zoned as residential property
  • Built prior to October 1, 1998
  • Free of major building code violations

Frequently Asked Questions


Acoustical: Conditions or products related to hearing, noise or sound.

Avigation Easement: The Avigation Easement will grant the use of airspace; the right of free, unrestricted, and unobstructed overflight, and the effects that may result from the over-flight of aircraft, aircraft taking off and/or landing at BWI Marshall Airport. The easement will run in perpetuity with the property.

Bid Package: A group of houses assembled together into one construction contract.

Condensation: The result of high humidity (moisture in the air) that produces a “fog” when it hits a colder surface such as a glass window.

Day-Night Level (DNL): Average Annual Sound Levels that represent the sound levels over a 24-hour period, while taking into account quiet periods as well as aircraft over- flights. For flights that occur after 10PM and before 7AM, these events receive a 10 dB penalty. The DNL noise exposure contours in the affected residential neighborhoods are 75 DNL to 65 DNL.

Decibel (dB): A unit of measure for the vibration (low rumble or high whistle) and strength (soft or loud) of sound waves. The higher the decibel level (vibration and strength), the louder the sound. Most sounds we experience in our day-to-day lives vary between 30 dB (a typical bedroom at night) and 100 dB (inside a nightclub).

Eligibility: Qualified to participate in the Sound Insulation Program by having a home or property located in the designated treatment areas and with an existing interior noise level that meets the FAA guidelines.

Federal Aviation Administration (FAA): The branch of the federal government which provides funding and oversight of the Residential Sound Insulation Program.

Homeowner Participation Agreement: An agreement between a homeowner and the MAA that authorizes the installation of specific sound insulation treatments at a given residential property.

Maryland Aviation Administration (MAA): The branch of the State of Maryland Department of Transportation that operates the Baltimore/Washington International Thurgood Marshall Airport, including the sponsorship of a Residential Sound Insulation Program.

Noise Level Reduction (NLR): Noise level reduction is measured in decibels and is defined as a constant numerical value between the interior noise level and the exterior noise level. This measurement is taken before and after acoustical treatments to determine the overall improvement in noise level reduction. This value will be used to compare the post-construction interior noise levels in the home to the FAA goal of below 45 DNL (Day-Night Level).

Noise Paths: The areas where environmental noise can travel from the outside through the home’s construction, with the greatest flow through doors, windows, vents, and/or lightly constructed wall and ceiling assemblies.

Punch List: A “to do” list made near the completion of construction work indicating the items that remain unfinished, or that do not meet the quality requirements specified in the scope of work. The Punch List must be satisfied prior to 100% completion.

RSIP: Residential Sound Insulation Program

RSIP Team: Personnel from the program managers, architects and engineers for the Residential Sound Insulation Program who will go to each home to gather information and make treatment recommendations.

Sound Insulation: The application of residential sound insulation can include some or all of the following: replacing or supplementing windows and doors; installing attic insulation; caulking and sealing. FAA residential sound insulation programs, including this Sound Insulation Program, are voluntary programs. Program participation is not a requirement.
