- Even though traditional psychoacoustics has provided indispensable knowledge about auditory perception, it has, in its narrow focus on signal characteristics, neglected listener and contextual characteristics. To demonstrate the influence of the meaning the listener attaches to a sound in the resulting sensations we used a Fourier-time-transform processing to reduce the identifiability of 18 environmental sounds. In a listening experiment, 20 subjects listened to and rated their sensations in response to, first, all the processed stimuli and then, all original stimuli, without being aware of the relationship between the two groups. Another 20 subjects rated only the processed stimuli, which were primed by their original counterparts. This manipulation was used in order to see the difference in resulting sensation when the subject could tell what the sound source is. In both tests subjects rated their emotional experience for each stimulus on the orthogonal dimensions of valence and arousal, as well as perceived annoyance and perceived loudness for each stimulus. They were also asked to identify the sound source. It was found that processing caused correct identification to reduce substantially, while priming recovered most of the identification. While original stimuli induced a wide range of emotional experience, reactions to processed stimuli were emotionally neutral. Priming manipulation reversed the effects of processing to some extent. Moreover, even though the 5th percentile Zwickers-loudness (N5) value of most of the stimuli was reduced after processing, neither perceived loudness nor auditory-induced emotion changed accordingly. Thus indicating the importance of considering other factors apart from the physical sound characteristics in sound design.

- Psychoacoustical research provided indispensible knowledge on how human audition works, which is necessary for successful sound design applications. It may, however, be argued that traditional psychoacoustics, in its narrow focus on signal characteristics, has neglected listener and contextual characteristics. Thus, to demonstrate the influence of meaning the listener attaches to a sound we used an FFT processing to reduce the identifiability of 18 environmental sounds, since source identification is central to meaning attribution. In a listening experiment, 20 subjects listened to and rated all the processed stimuli first and then original stimuli, without being aware of the existence of two sets. Another 20 subjects rated only the processed stimuli, which were primed by their original counterparts. This manipulation was used in order to see the difference when the subject could tell what the sound source is. In both tests subjects rated their emotional experience for each stimulus on the orthogonal dimensions of valence and arousal, as well as perceived annoyance and perceived loudness for each stimulus. They were also asked to identify the sound source. It was found that processing caused correct identification to reduce substantially, while priming recovered most of the identification. While original stimuli induced a wide range of emotional experience, reactions to processed stimuli were affectively neutral. Priming manipulation reversed the effects of processing to some extent. Moreover, even though Zwickers-loudness value of most of the stimuli was reduced after processing, perceived loudness was only decreased for affectively negative stimuli.

Emotion and meaning in interpretation of sound sources

- Research regarding the perception of sound focuses in large on the acoustical properties of the sound. We argue that, for a more complete picture of sound perception, one must take the non‐physical properties into account. By changing the emotional descriptor of a sound the perception in terms of level of annoyance will change. The present study investigates how a priming picture placing the origin of the sound in either a positive or negative environment affects the level of annoyance to same sound. Three different sounds were used in the experiment, all based on pink noise. The participants were, in the beginning of each sound, exposed to a picture telling where the sound originated. The picture was either a positive environment (a picture of a waterfall) or a negative environment (a picture of a larger factory). While listening to the sounds the participants completed different performance tasks. In the end of each sound the participants rated the level of annoyance. Results show that the annoyance ratings are significantly lower when primed with a positive picture. Results also indicate that for more attention demanding tasks this correlation is stronger. The findings are discussed in relation to theories of sound perception.

Perceptual and emotional categorization of sound

- This paper investigates how different types of data from psychoacoustical experiments may be combined to render further knowledge about the mechanisms underlying sound perception. Two studies were conducted with auditory alerts of short duration. First, an experiment where participants rated the dissimilarity among the auditory alerts was performed. This resulted in a two-dimensional multi-dimensional scaling solution. Second, an experiment where participants evaluated the stimuli with semantic descriptors and rated their emotional reactions to the sounds was performed. The output of this experiment was a reduced set of underlying perceptual and emotional dimensions. The results of the two experiments were then integrated by the use of multi-dimensional perceptual unfolding and a set mediation analyses. The integrative analyses showed that part of the cognitive categorization of the semantic descriptors was mediated by the emotional reactions to the sounds. The results are discussed in relation to theories of auditory perception and emotional response categorization.

Perceptual validation of auralized heavy-duty vehicles

- Auralization is a valuable tool when evaluating the effect of traffic noise on people. The present study focuses on the validation of auralization of heavy-duty vehicles with a diesel engine. To capture the characteristics of the diesel engine a granular approach has been used. The granular approach has proven to be successful in a previous validation test examining two microphone positions around a still-standing truck. In the present study a granular approach was used to achieve pass-by noise at an artificial listening position alongside a Volvo truck (experiment 1) and pass-by noise inside an apartment (experiment 2). The aim of experiment 1 was to determine the number of interpolated sets of grains needed, in order to create a perceptually valid auralized signal. The results were used in the auralization of pass-by noise in an apartment in experiment 2. 20 and 15 participants respectively rated original recordings and auralized signals on four different attributes: realism, annoyance, and emotional response measured by valence and arousal. The results of both experiments suggest that auralizations of heavy-duty vehicles are successful and usable. It further indicates that what distinguish the auralized signals from the original recordings is mostly the arousal responses.

- With increased stressful situations in the society the demands for restorative environments with a high ability to reduce stress increase. Studies of urban soundscapes have mainly focused on what kind of sounds that cause annoyance, or increase stress. Fewer have addressed the opposite: how may sound decrease perceived stress levels? Visual modality studies show a high correlation between preferred environments and their ability to reduce stress levels. Hypothetically the same should apply within the auditory modality. In order to study the possible effect of preferred sounds as a moderator for stress reduction: 24 participants were exposed to a stress inducing computer game and a subsequent rest while listening to either preferred or non-preferred sounds. The sounds were environmental sounds and rated by each participant in terms of preference before the experiment started. Experienced stress was measured right after the stress induction and after 20 minute long rests. The results show a significant decrease of perceived stress when exposed to preferred environmental sounds. When listening to the less preferred sounds during the rest there was no significant reduction of perceived stress. The results will be discussed in relation to theories of emoacoustics and attention restoration.
