Noise annoyance caused by continuous descent approaches compared to regular descent procedures

During Continuous Descent Approaches (CDAs) aircraft glide towards the runway resulting in reduced noise and fuel usage. Here, we investigated whether such landings cause less noise annoyance than a regular stepwise approach. Both landing types were compared in a controlled laboratory setting with a Virtual Community Noise Simulator (VCNS),...

Annoyance by transportation noise: The effects of source identity and tonal components

Aircraft noise is consistently rated as more annoying than noise from other sources with similar intensity. In three experiments, it was investigated whether this penalty is due to the source identity of the noise. In the first experiment, four samples were played to participants engaged in a working memory task: road traffic noise, an Airbus...

The effect of the number of aircraft noise events on sleep quality

Background Both the WHO and the EC recommend the use of Lnight as the primary indicator for sleep disturbance. Still, a key question for noise policy is whether the prediction of sleep quality could be improved by taking the number of events into account in addition to Lnight. Objectives The current paper investigates the association between...

Trends in aircraft noise annoyance: The role of study and sample characteristics

This study assesses the effects of aircraft noise on residential satisfaction, an important indicator of subjective well-being. A structural equation model is specified that estimates the relationships between objective variables, noise annoyance variables and residential satisfaction. Secondary data-analysis is used to estimate the model. The...

The role of study characteristics in changes in aircraft noise annoyance over time

On the basis of findings from recent surveys, discussion has been raised as to whether the annoyance of residents at a given aircraft noise exposure level has increased over the years. To verify the hypothesized trend and to identify its possible causes, the large database used to establish earlier exposure-response relationships was updated...

Noise annoyance from stationary sources: Relationships with exposure metric day-evening-night level (DENL) and their confidence intervals

Relationships between exposure to noise [metric: day-evening-night levels (DENL)] from stationary sources (shunting yards, a seasonal industry, and other industries) and annoyance are presented. Curves are presented for expected annoyance score, the percentage "highly annoyed" (%HA, cutoff at 72 on a scale from 0 to 100), the percentage "annoyed...

Assessment methods for personal Active Noise Reduction validated in an international round robin [Méthodes d’évaluation des protecteurs auditifs à atténuation active du bruit]

Hearing protection with standard passive earmuffs is for many military applications insufficient. Low frequency noises (diesel engines, helicopter rotor) require increased attenuation. Active Noise Reduction (ANR) is specifically suited for reduction at low frequencies. Assessment of ANR for military applications is an important topic as the...

Noise sensitivity and reactions to noise and other environmental conditions

This article integrates findings from the literature and new results regarding noise sensitivity. The new results are based on analyses of 28 combined datasets (N=23 038), and separate analyses of a large aircraft noise study (N=10939). Three topics regarding noise sensitivity are discussed, namely, its relationship with noise exposure, its...

Aircraft noise exposure from Schiphol airport: A relation with complainants

The possible relation between aircraft noise exposure and the prevalence of complainants around Schiphol airport was studied. The home address of people who complain about aircraft noise at the Environment Advisory Committee Schiphol was combined with annual average noise levels, using a Geographic Information System. The prevalence of...

Community reaction to aircraft noise: Time-of-day penalty and tradeoff between levels of overflights

A decrease in the level of sound events can compensate for an increase in the level of other events, but noise metrics assume different tradeoffs. Noise metrics also differ in the penalty applied to noise in the evening and to noise in the night, and in the definition of these periods. These two aspects of noise metrics, i.e., the tradeoff and...

Exposure-response relationships for transportation noise

This article presents synthesis curves for the relationship between DNL and percentage highly annoyed for three transportation noise sources. The results are based on all 21 datasets examined by Schultz [J. Acoust. Soc. Am. 64, 377-405 (1978)] and Fidell et al. [J. Acoust. Soc. Am. 89, 221-233 (1991)] for which acceptable DNL and percentage...
