“…It is important to note that for ease, we have labeled the 2 dimensions "calmness" and "vibrancy", however it must be remembered that the full semantic descriptors for these dimensions should be used, in order to represent accurately the semantic meaning of the dimension. Barbot et al [28] for instance, noted that the meaning of the adjectives can be difficult to interpret by subjects and can even be different between subjects, which is why it is important to fully describe our emotional dimensions with multiple semantic descriptors.…”

“…This study yielded over 280 comments. This technique of using free verbalizations to describe perceptions of sound and emotional responses to sound allows us to use language to study auditory judgements (and has previously been used to investigate perceptions of aircraft sound [28] and low frequency sound perception in urban areas [23] for example).…”

“…3,6,7 Generally, it was shown that noises composed of regular amplitude modulations tend to be more annoying than noises with irregular amplitude variations. A study by Kantarelis and Walker 10 demonstrated the importance of amplitude modulation in the context of noise annoyance from engine noise of locomotives.…”

The models that relate noise annoyance assessments to noise signal parameters are mainly based on energy-related indices (e.g., LDEN). However, various studies have shown that sound characteristics of environmental noises linked to temporal and spectral signal features also influence noise annoyance responses. In order to enhance noise annoyance models, an adequate perception-related characterization of these influential acoustical features is essential. On the basis of urban road single-vehicle pass-by noises, this study will show the identification of noise characteristics that rely on spectral and temporal signal properties and that are related to noise annoyance. Based on a semantic differential test with a verbalization task, it will be shown that the sensation dull/shrill, related to the spectral content of the noises and the modulation-related sensations sputtering and nasal are linked to annoyance. The sensation dull/shrill could be characterized using the index TETC (Total Energy of Tonal Components within critical bands from 16 to 24 barks). The correlation of sputtering and nasal sensations with psychoacoustic indices was unsatisfactory. Two alternative indices are proposed to improve the characterization of these specific sensations. It is shown that noise annoyance assessment benefits from taking the TETC index and the sputtering and nasal indices into account.

“…There is no agreement in the specific order of these two noise features, as some participants reported the amplitude modulated noise as the least preferable feature, and others the 'high pitch' noise. 'High pitch' noise has been found to be an important contributor to the human perception of aircraft noise during takeoff [47].…”

On the assessment of subjective response to tonal content of contemporary aircraft noise

The Effective Perceived Noise Level (EPNL) is the primary metric used for assessing subjective response to aircraft noise. The EPNL comprises calculation of the Perceived Noise Level (in PNdB), and takes into account flyover duration and the presence of pure tones to arrive at an adjusted EPNL value. With the presence of a single significant tone, EPNL has been found to be reasonably effective for the assessment of aircraft noise annoyance. Several authors have, however, suggested that EPNL is not capable of quantifying the subjective response to aircraft noise that contains multiple complex tones. The noise source referred to as "Buzz-saw" noise is a typical example of complex tonal content in aircraft noise with an important effect on both cabin and community noise impact. This paper presents the results of a series of listening tests where a number of participants were exposed to samples of aircraft noise with six variants of aircraft engines, assumed representative of the contemporary twin engine aircraft fleet. On the basis of the findings of these listening tests, the Aures tonality method significantly outperforms the EPNL tone correction method when assessing the subjective response to aircraft noise during takeoff with the presence of multiple complex tones. The participants reported 'high pitch' as one of the least preferable aircraft noise characteristics, and consequently, the psychoacoustics metric Sharpness was found to be another important contributor to subjective response to the noise of two specific aircraft engine groups (out of the six considered). The limitations of Aures tonality are discussed, in particular for aircraft noise with both a series of complex tones spaced evenly across the frequency spectrum with relatively even sound levels and less subjectively dominant single frequency tones (compared to broadband noise). In line with these limitations, further work is proposed for more effective assessment of subjective response to aircraft noise containing significant tonal content in the form of numerous closely spaced or other complex tones.
