Influence of a wearer's voice on noise dosimeter measurements.

In recent years, interest in personal noise exposure has expanded beyond a workplace safety measure to become an effective means of investigating physiological effects of the acoustic environment on an individual. This work investigates the effects of the wearer's voice as a possible dominant sound source on body-mounted noise dosimeters and develops methods to improve the application of dosimeter measurements in medium-level noise environments. Subjects experienced a controlled set of acoustic conditions while wearing a dosimeter.

When room size matters: acoustic influences on emotional responses to sounds.

When people hear a sound (a "sound object" or a "sound event") the perceived auditory space around them might modulate their emotional responses to it. Spaces can affect both the acoustic properties of the sound event itself and may also impose boundaries to the actions one can take with respect to this event. Virtual acoustic rooms of different sizes were used in a subjective and psychophysiological experiment that evaluated the influence of the auditory space perception on emotional responses to various sound sources.

Evaluation of decay times in coupled spaces: reliability analysis of Bayeisan decay time estimation.

This paper discusses quantitative tools to evaluate the reliability of "decay time estimates" and inter-relationships between multiple decay times for estimates made within a Bayesian framework. Previous works [Xiang and Goggans, J. Acoust.

Simultaneous acoustic channel measurement via maximal-length-related sequences.

A wide variety of acoustic systems has multiple sources and receivers. This paper proposes a technique for making acoustic measurements simultaneously for multiple sources. The proposed technique features a collection of excitation signals of the maximum-length sequence (MLS) and MLS-related classes.

Preference for current mood, anticipated emotional reaction, and experienced emotional reaction.

Two experiments investigated how preference for emotions is related to valence and activation of current mood, anticipated emotional reaction, and experienced emotional reaction. In Experiment 1, 40 undergraduates on one occasion rated valence and activation of and preference for their emotional reaction to an aircraft noise, then on a later occasion rated valence and activation of and preference for their recalled or anticipated emotional reaction to the same aircraft noise. On both occasions they also rated valence and activation of current mood.

Emotion and auditory virtual environments: affect-based judgments of music reproduced with virtual reverberation times.

Emotions are experienced both in real and virtual environments (VEs). Most research to date have focused on the content that causes emotional reactions, but noncontent features of a VE (such as the realism and quality of object rendering) may also influence emotional reactions to the mediated object. The present research studied how noncontent features (different reverberation times) of an auditory VE influenced 76 participants' ratings of emotional reactions and expressed emotional qualities of the sounds.

The measurement of core affect: a Swedish self-report measure derived from the affect circumplex.

Three studies were conducted with the aim of developing a new Swedish self-report measure of core affect (the Swedish Core Affect Scale or SCAS). In Study 1,122 participants rated their current mood on 24 unipolar adjective scales. A revised set of 12 bipolar adjective scales was evaluated in Study 2 employing 96 participants who rated their current mood before and after a mood-inducing naturally occurring event.
