TLDR
It seems possible to use this continuous assessment method so that the temporal hedonic evaluation of a long sequence can be obtained and that the most annoying events can be identified.Abstract:
A binaural recording, realized inside an autobus running according to a typical urban sequence, has been used in several ways : - first of all, listeners had to continuously assess the annoyance of the using the categorical continuous method, introduced by Weber for the assessment of loudness. It has been proved that this task is achievable by listeners, even if it is a difficult one. This evaluation has allowed to identify the events inducing annoyance; - then, sound extracts representing these annoying events have been numerically modified and assessed by a pair comparison method so as to identify the optimal modification for each of them; - lastly, the whole signal has been modified in accordance with the results of the previous step. Then, other listeners had to assess both original and modified signals in a continuous and global way. This part has shown that the assessment has undoubtedly concerned the annoyance issue and not the sound level one, because individual differences have appeared among the members of the jury. It thus seems possible to use this continuous assessment method so that the temporal hedonic evaluation of a long sequence can be obtained and that the most annoying events can be identified.read more

The influence of auditory feedback on speed choice, violations and comfort in a driving simulation game
TL;DR: In this article, the authors explore the relationship between auditory feedback (engine noise), speed choice, driving violations and driver comfort, and find that low levels of engine noise feedback (no feedback and 70 dB(A)) were associated with increases in driving speed, and driving violations relative to higher levels of feedback (75 dB (A) and 80 dB(E)).

A psychoacoustical study of wind buffeting noise
TL;DR: In this article, a study of the perception of wind buffeting, potentially deleterious to the sound quality of a vehicle, was conducted in a wind tunnel with a specific module designed to simulate mild or severe buffeting.

Continuous judgment of level-fluctuating sounds and the relationship between overall loudness and instantaneous loudness
Sonoko Kuwano,Seichiro Namba +1 more
TL;DR: The results suggest that instantaneous loudness is determined by the sound energy averaged during the 2.5-s period preceding each judgment, the duration of which seems to reflect the psychological present.
Global and Continuous Loudness Estimation of Time-Varying Levels
TL;DR: In this article, two cross-modal matching methods were used, one with continuous force feedback and another without force feedback but using a continuous analogical/categorical judgment scale, to evaluate continuously or globally the loudness of pure tones of variable duration and time-varying level.
