| Zusammenfassung | Introduction: At many immission sites of infrasound (frequency f < 20 Hz), humans are exposed to a mixture of infrasound and sound in the common audio-frequency range (audio sound, 20 Hz < f < 20 kHz). It is, therefore, of special interest to examine the auditory perception of infrasound and audio sound not only in isolation but also in combination. Methods: This laboratory study aims to investigate the perceived unpleasantness of infrasound (sinusoid at 12 Hz) and audio sound (sinusoid at 1000 Hz, pink-noise 250-4000 Hz), presented alone or in combination with each other. A pairwise comparison task and a rating task using a numerical scale were conducted with 19 normal hearing listeners. In addition, individual detection thresholds were determined for the infrasound stimulus. Results: Combinations of infrasound and audio sound were rated as equally or more unpleasant than either sound presented alone. Inter-individual differences in unpleasantness ratings were especially high for stimuli containing infrasound, which can only in part be related to the large variability in infrasound thresholds. Discussion: These findings suggest that a simultaneous exposure to infrasound and audio sound can increase the perceived unpleasantness when both were presented at a sufficient level above the detection threshold. |
