“…The stimuli were presented via Sennheiser HDA200 headphones connected to a PC with MATLAB 2,13 The selection of this duration was based on studies concluding that a stimulus length as short as 30 s can give comparable results to long stimuli. 15,16 Therefore, the standard duration of all stimuli for this study was selected to be equal to 30 s.…”

Amplitude modulation (AM) may be an important factor for the perceived annoyance of wind turbine noise (WTN). Two AM types, typically referred to as "normal AM" (NAM) and "other AM" (OAM), characterize WTN AM, OAM corresponding to having intermittent periods with larger AM depth in lower frequency regions than NAM. The extent to which AM depth, frequency, and type affect WTN annoyance remains uncertain. Moreover, the temporal variations of WTN AM have often not been considered. Here, realistic stimuli accounting for such temporal variations were synthesized such that AM depth, frequency, and type, while determined from real on-site recordings, could be varied systematically. Listening tests with both original and synthesized stimuli showed that a reduction in mean AM depth across the spectrum led to a significant decrease in annoyance. When the spectrotemporal characteristics of the original far-field stimuli and the temporal AM variations were taken into account, the effect of AM frequency remained limited and the presence of intermittent OAM periods did not affect annoyance. These findings suggest that, at a given overall level, the AM depth of NAM periods is the most crucial AM parameter for WTN annoyance.

“…(1)]. 15 The MD for the frequency band around 1 kHz is defined as the difference between the maximum and minimum values of the sound pressure of this signal: MD ¼ 20 log [(p 1 þ p 0 )/(p 1 À p 0 )] ¼ 20 log (p max /p min ) (dB). Applying this equation to all specified frequency octaves leads to the calculation of the MDS, which is given in Fig.…”

“…Poulson studied the influence of session length on annoyance and perception of traffic and impulse noise at levels of 35, 50, and 65 dBA, using exposure times ranging from one to 30 minutes. 12 He found insignificant correlations between the results and test duration. He consequently suggested that 5 minutes is long enough to gain a reliable estimation of annoyance.…”

The influences of exposure time and the types of tasks on human perception and task performance have been investigated under a variety of noise conditions with differing level, spectral content, and behavior over time. Ten test subjects each completed 38 hours of testing over multiple days. Subjects were exposed to each of six background noise conditions over 20, 40, 80, and 240 minute trials. During the trials, subjects completed three types of performance tasks (typing, grammatical reasoning, and math tests) and answered questions about their perception of the indoor environment. Results indicate that the different exposure lengths used in this study did not have a significant effect on performance scores. Some influence of exposure time on subjective perception was observed, however; shorter time lengths combined with back to back exposures led to greater differentiation in perception. Significant differences in task performance between the different noise conditions were not observed, but differences in perception were found.Additionally, task performance was related to subjective perception; if subjects perceived the noise to be more tonal, they performed worse on all tasks. The performance results were not always negatively influenced by unfavorable quality perceptions, though. For example, as subjects perceived noise to be more roaring in this study, their typing scores decreased but reasoning and math scores improved. © 2007 Institute of Noise Control Engineering.
