SOUND PROOFING - BOSTON MASSPORT
The extent of homes that are soundproofed in any given year is subject to the availability of federal grants, the number of homes already in the program to be soundproofed and the capacity of Massport hired contractors to complete the work. The annual 65 DNL is a FAA set standard. You may experience noise from Logan related aircraft but not qualify for soundproofing. This is because you may live just outside the 65 DNL and, although on any given day noise from aircraft may be loud, on an annual basis it does not reach the 65 DNL threshold.
Because noise changes from year to year, the FAA requires Massport to periodically submit a new sound exposure map for their review and approval. Therefore, eligibility for any particular home may change over time.
The FAA has designated 65 DNL annual contour as the critical threshold to use for soundproofing eligibility. Massport submits to the FAA for approval a 65 DNL noise contour for a specific year. After FAA approval, Massport uses the 65 DNL contour to determine residential sound proofing. To determine eligibility, a home must fall within the FAA approved sound exposure map. To determine if you are eligible we encourage you to write or email Massport. Based on the address you provide, we will determine if you are eligible.
