“…The results found in this latest effort mirror some of the findings in the PI (Nykaza et al 2010b) and the Complaint Survey Protocol (CS) (Nykaza et al 2010a(Nykaza et al , 2011. The PI study was conducted at three different military installations, with one of these locations being the same as the current study.…”

“…This method of assessment was adopted for consistency with the method recommended by many Federal agencies to assess transportation noise impacts-the percent highly annoyed as a function of the A-weighted Day-Night Level (ADNL) (Schultz 1978). It has been recognized for some time, though, that the average sound level is an inadequate predictor of annoyance; the percent of the population highly annoyed by a given noise source is only weakly correlated with the DayNight Level (CHABA 1996;Valente et al 2011), and this correlation shows large variance from community to community (i.e., some communities are more tolerant of a given noise source than others [Green and Fidell 1991]). …”

Current blast noise assessment procedures at military installations in the United States do not fully meet the military's noise management needs; military blast noise sometimes disturbs surrounding communities, resulting in legal actions against US military installations. Specifically, current procedures do not accurately capture the way humans respond to blast events, and do not adequately account for the level, number, timing, and spatial variability of blast noise events. This work constructed and administered the General Community Survey (GCS) within SERDP Project WP-1546 at the first of three military installations to determine how blast noise levels affect general community annoyance and how the community reaction changes over time in response to a dynamic blast noise environment. The results indicate that, while blast noise was the most annoying noise source around this installation, current blast noise assessment metrics are weakly correlated with community annoyance, and a large percentage of the study population were highly annoyed at relatively low C-weighted Day-Night blast noise levels. Current findings highlight the importance of capturing temporal and spatial variation of the both stimulus and response, and also of non-acoustical factors such as habituation and vibration.

“…1,2 Recent research provides evidence that the prevalence of annoyance depends strongly on the attitudes of a particular community toward the noise producing activity; therefore, the predictive value of the acoustical metrics alone is limited. 3,4 Fidell et al 4 thus proposed a model in which each community has its own characteristic noise tolerance, namely, y ¼ e ÀA=m , where y is the fraction of respondents that are highly annoyed by the noise, A is a community-specific constant accounting for non-DNL factors on annoyance, and m ¼ ð10 L dn =10 Þ 0:3 is the estimated noise dose, which relates the rate of growth in annoyance to DNL.…”

Statistical evidence for various models relating day-night sound level (DNL) to community noise annoyance is assessed with the Akaike information criterion. In particular, community-specific adjustments such as the community tolerance level (CTL, the DNL at which 50% of survey respondents are highly annoyed) and community tolerance spread (CTS, the difference between the DNL at which 90% and 10% are highly annoyed) are considered. The results strongly support models characterizing annoyance on a community-by-community basis, rather than with complete pooling and analysis of all available surveys. The most likely model was found to be a 2-parameter logistic model, with CTL and CTS fit independently to survey data from each community.

Military installations typically rely on noise complaints to indicate adverse noise environments and often restrict the firing of certain weapons to reduce the number of noise complaints. Using complaints in this manner may also imply that the absence of complaints is an indicator of low community annoyance. The relationship between individual complaints and general community annoyance, however, is currently not established, and it is unknown whether implementing restrictions in reaction to individual complaints is an appropriate or necessary way to reduce community annoyance. This paper looks at whether there are significant differences in reported annoyance to complaint-referenced blast events and general military noise annoyance between those who complain and their non-complaining neighbors. Those who complained were significantly more annoyed to both complaint-referenced blast events and general military noise in comparison to their non-complaining neighbors. The implications of these findings are discussed in terms of range management.
