What is the FAA's recommended noise limit for significant mitigation efforts?

The FAA's recommended noise limit for significant mitigation efforts is set at 65 decibels (dB). This threshold is significant because it aligns with the guidelines and initiatives aimed at reducing environmental noise impacts, particularly around airports. The 65 dB level is often used as a baseline to assess the need for noise abatement programs and to evaluate the effectiveness of various noise mitigation strategies.

Communities located near airports experience noise pollution that can affect the quality of life for residents. By targeting noise levels at or above 65 dB, the FAA seeks to implement practices that can alleviate the adverse effects of aircraft noise, thereby promoting a balance between aviation growth and community sustainability. This standard is part of a broader commitment to ensure that aviation operations minimize disturbances to the surrounding environment and maintain public health and welfare.
