Appendix G Suggested Annoyance Survey Research Protocol The primary goal of this proposed new national survey of aircraft noise annoyance in the United States is to update previous estimated dose-response relationships and provide a best estimate of the relationship between aircraft noise exposure and the self-reported annoyance of residents for the nation as a whole.

For completed interviews, specific values of DNL and other noise metrics will be determined, (for our proposed methods for determining the noise contours and respondent noise metrics, see "Determining Noise Exposure," Phase 3)

Our survey instrument will, nevertheless, include some questions about personal variables to confirm that they still remain, for the most part, insignificant. On the other hand, our analysis will test for differences in annoyance in different communities, at different airports and in different climates.

During the time of the OMB review, we will simultaneously conduct work that falls conceptually under Data Collection, Phase 3. We propose to conduct these efforts – mainly noise exposure computations – so that once the OMB review is complete and our approach approved, we can immediately start identifying possible respondents and quantifying their noise exposures and be ready to commence surveying immediately after the first year.

completion, would allow more efficient use of fieldwork, and would ensure that all airports are surveyed under comparable conditions to allow ready comparison and pure estimates of airport heterogeneity. It would also allow seasonality to be considered for each airport, and would decrease the airport-to-airport variability, since the seasonality effects would be removed from the variability.

The final sampling stage is to select at each selected address a sample of eligible adults to take the survey. One possibility is to select all persons at sampled addresses.

It selects the specific airframe and engine combination to model on an operation-by-operation basis, resulting in a far more detailed and truly representative fleet mix. RealContours™ does not modify any of the noise and performance data in the INM, nor does it modify the computational algorithms.

We will acquire flight track data for each airport.

The data collection approach follows the sequential administration of the surveys as specified in response to questions to the RFP. Sampled households at a single airport will be administered the survey using the procedures specified below.
