TRB Releases HMMH-Authored Report on Aircraft Noise Annoyance and Sleep Disturbance

Tuesday, July 29th, 2014

HMMH is pleased announce the release of the Transportation Research Board (TRB)’s Airport Cooperative Research Program (ACRP) Report 17: Research Methods for Understanding Aircraft Noise Annoyances and Sleep Disturbance. HMMH led a research team to develop and validate a research protocol for a large-scale study of aircraft noise exposure-annoyance response relationships across the US, and to propose alternative research methods for field studies to assess the relationship between aircraft noise and sleep disturbance for U.S. airports.

The first phase of this ACRP Study included the collection of data for the purpose of testing an aircraft noise annoyance survey, for use in a national study, to update the dose-response relationship between noise exposure and the percentage of people who are highly annoyed. The second phase, the sleep disturbance portion of the ACRP Study, included:

  1. Developing at least two general research protocols to improve the understanding of the relationship between aircraft noise and sleep disturbance in a field setting; and
  2. Identifying criteria to be used to test and evaluate the protocols.

The report describes the annoyance survey methodology that was developed and applied and the results relevant to the goals of the study. It also discusses airport-community relations and presents the final sleep disturbance study designs and budget estimates for each type of study.

This project validated the approach that will be used in the surveys that FAA will conduct at 20 airports, with HMMH-led assistance.  The HMMH team currently is working with the FAA to refine the survey methods based on the results of the Study and to develop an appropriate statistical process for randomly selecting the 20 representative airports.

TBT: Grand Canyon Noise Measurements, September 1999

How about a four day, all-expense paid camping trip in the Grand Canyon?  All our eight teams of four people each had to do was listen for aircraft eight hours a day.  The goal was to determine which noise model best predicted tour aircraft audibility.  Thanks to Rick Ernenwein and the late Wes Henry for making it all possible.  What a team!

TBT: Noise Measurements at Idlewild

Thursday, July 17th, 2014

by Mary Ellen Eagan

I’ve been spending a lot of time the last few weeks thinking about evolution of noise issues at the Port Authority (of New York and New Jersey), and thought some of you might also appreciate these photos of early efforts to measure noise levels at JFK (then-Idlewild).

John Wiley and Austin Tobin are standing second and third from the left, respectively.  The others are representatives from British Airways and the Port of New York Authority.
