Glossary

AIP grant funds:

  • The Airport Improvement Program (AIP) is a federal grant program that provides funding for eligible airport projects, such as the Acoustical Treatment Program.

Avigation Easement:

  • In order to receive the proposed Acoustical Treatment modifications, the homeowner(s) must sign an avigation easement which grants WBA the right of flight over the residence. The easement does not limit homeowner(s) rights in cases of negligence or accident.

Construction Agreement:

  • The homeowner(s) must sign a Construction Agreement outlining the responsibilities of each party and agreeing to the proposed package of Acoustical Treatment modifications. Once the Construction Agreement is signed, the homeowner(s) are obligated to receive the Acoustical Treatment modifications.

Day-Night Average Sound Level (DNL):

  • DNL is a method of averaging total sound energy over a 24-hour period. In the DNL calculation, all flights between 10 p.m. and 7 a.m. have a 10 dB (decibel) penalty added to them before they are averaged in with the daytime flights. This is because nighttime flights are more intrusive than similar daytime events. Since DNL is an average, it does not reflect how loud an individual flyover is at any given house. Homes that are currently located in the 65 - 69 DNL contour on the approved Noise Exposure Map may be eligible for Acoustical Treatment.

Decibel (dB):

  • Sound energy is measured in units called decibels. The decibel scale does not increase or decrease using standard arithmetic. For example, reducing a noise level by 3 dB actually means the sound energy has been cut in half. For example, a noise level of 65 dB has half as much sound energy as a noise measuring 68 dB.

FAA: Federal Aviation Administration:

  • U.S. Department of Transportation agency that oversees civil aviation.

Westfield-Barnes Airport Commission:

  • The governing body of the Westfield-Barnes Airport.

Noise Exposure Map:

  • This map shows the DNL noise contours which are used to determine eligibility for the Acoustical Treatment Program.

Noise Test:

  • This test, conducted by Wyle, lasts approximately 1-2 hours. The acoustical engineer will measure existing noise levels by artificially producing aircraft noise inside the home using a loudspeaker and measuring the sound transmission properties of the home.

FAR Part 150 Noise Compatibility Study:

  • A voluntary program that allows an airport to work with the local community (homeowners and elected officials), airlines, FAA, and other interested parties to determine feasible and reasonable solutions to the impact of aircraft noise on communities surrounding the airport.

Pre-modification Survey:

  • A brief questionnaire concerning your feelings about the current noise environment in the various habitable rooms of your home.

Post-modification Survey:

  • A brief questionnaire concerning your feelings about noise in your home after completion of the Acoustical Treatment modifications.

Request to Participate (RTP):

  • This document gives the Acoustical Treatment Program permission to perform tests and measurements on your home to determine what modifications are necessary to achieve the required sound reduction goals. This document does not bind you to receiving the Acoustical Treatment modifications.

RNMP:

  • Residential Noise Mitigation Program

STC rating:

  • STC stands for Sound Transmission Class. This is the standard way of rating Acoustical Treatment qualities in building products. A higher STC rating means better noise reduction. For example, brand new thermo-pane windows typically provide an STC of 28-32. Our designs require acoustical windows with a minimum STC rating of 40.
