- 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.

The pleasant heat? Evidence for thermal-emotional implicit associations occurring with semantic and physical thermal stimulation
- 2015

Journal article (peer-reviewed)abstract
- The association between thermal and emotional experiences in interpersonal relations is intuitively apparent and has been confirmed by previous studies. However, research has not yet elucidated whether such an association is grounded in mental processes occurring at an intrapersonal (internal) level. In two experiments we examined whether the thermal-emotional associations can be observed at an intrapersonal level. We looked at the speed and accuracy of stimuli categorization. Experiment 1 examined the implicit semantic association between temperature (warm versus cold) and emotional valence (positive versus negative). Experiment 2 examined the association between experience of physical temperature and emotional valence. In both experiments warm-positive/cold-negative associations were demonstrated. These results suggest a conceptual and perceptual mapping in the mental representation of emotion and temperature, which occurs at an intrapersonal level, and which might serve as the ground to the interpersonal thermal-emotional interactions.

Affective multimodal displays: Acoustic spectra modulates perception of auditory-tactile signals

Conference paper (peer-reviewed)abstract
- Emotional events may interrupt ongoing cognitive processes and automatically grab attention, modulating the subsequentperceptual processes. Hence, emotional eliciting stimuli might effectively be used in warning applications, where a fast and accurate response from users is required. In addition, conveying information through an optimum multisensory combination can lead to a further enhancement of user responses. In the present study we investigated the emotional response to sounds differing in their acoustic spectra, and their influence on speeded detection of auditory-somatosensory stimuli. Higher soundfrequencies resulted in an increase in emotional arousal. We suggest that emotional processes might be responsible for the different auditory-somatosensory integration patterns observed for low and high frequency sounds. The presented results might have important implications for the design of auditory and multisensory warning interfaces.

Book chapter (other academic/artistic)abstract
- Interpreting and responding to affective states of a user is crucial for future intelligent systems. Until recently, the role of sound in affective responses has been frequently ignored. This article provides a brief overview of the research targeting affective reactions to everyday, ecological sounds. This research shows that the subjective interpretation and meaning that listeners attribute to sound, the spatial dimension, or the interactions with other sensory modalities, are as important as the physical properties of sound in evoking an affective response. Situation appraisal and individual differences are also discussed as factors influencing the emotional reactions to auditory stimuli. A study with heartbeat sounds exemplifies some of the introduced ideas and research methodologies, and shows the potential of sound in inducing emotional states.

Auditory–somatosensory multisensory interactions are spatially modulated by stimulated body surface and acoustic spectra
- 2009

Journal article (peer-reviewed)abstract
- Previous research has provided inconsistent results regarding the spatial modulation of auditory–somatosensory interactions. The present study reports three experiments designed to investigate the nature of these interactions in the space close to the head. Human participants made speeded detection responses to unimodal auditory, somatosensory, or simultaneous auditory–somatosensory stimuli. In Experiment 1, electrocutaneous stimuli were presented to either earlobe, while auditory stimuli were presented from the same versus opposite sides, and from one of two distances (20 vs. 70 cm) from the participant's head. The results demonstrated a spatial modulation of auditory–somatosensory interactions when auditory stimuli were presented from close to the head. In Experiment 2, electrocutaneous stimuli were delivered to the hands, which were placed either close to or far from the head, while the auditory stimuli were again presented at one of two distances. The results revealed that the spatial modulation observed in Experiment 1 was specific to the particular body part stimulated (head) rather than to the region of space (i.e. around the head) where the stimuli were presented. The results of Experiment 3 demonstrate that sounds that contain high-frequency components are particularly effective in eliciting this auditory–somatosensory spatial effect. Taken together, these findings help to resolve inconsistencies in the previous literature and suggest that auditory–somatosensory multisensory integration is modulated by the stimulated body surface and acoustic spectra of the stimuli presented.
