Infrasound and its effects on the human body
We are part of a research project at Lübeck University of Applied Sciences on the subject of infrasound and its effects on the human body. Here is a brief insight: the two study leaders Mario Röcher and Lina Langanki are exploring the possible correlation between pulse and infrasound values using an innovative approach.
The study procedure was comprehensive and precise:
Briefing the subjects: An important step to ensure that all participants were familiar with the study (see picture with pen).
Pulse oximeter connection: Participants were fitted with pulse oximeters on their fingers to take precise pulse readings during the experiment.
Presentation of a short film: During this, not only were pulse and infrasound values measured, but the participants’ reactions to visual stimuli were also recorded.
Completion of a questionnaire: Finally, the participants completed a questionnaire to record their subjective impressions.
Measurements with state-of-the-art technologies and software such as REW – Room Acoustics Software and MatLab
The listening project goes beyond the purely physiological aspects and raises the question of the invisible effect of infrasound in combination with positive visual stimuli. The alternative hypothesis suggests that the simultaneous presentation of infrasound and positive visual stimuli leads to significant improvements in the mood of the audience. This could be demonstrated by parameters such as heart rate, skin conductance or mood changes. The measurements, both the room measurements and the subject measurements, were carried out carefully and cover a wide range of parameters, from the room acoustics to the psychological effects on the participants. State-of-the-art technologies and software such as REW – Room Acoustics Software and MatLab were used. The precise planning of the subject measurements on different days and the consideration of physiological and psychological differences underline the depth of this study. We expect to gain insightful knowledge about the interaction of infrasound and visual stimuli on human well-being and are very pleased to make our award-winning Movie Core available for this purpose.
Our “test laboratory” for the study – the Movie Core: 88 square meters, 390 cubic meters of room volume enclosed in solid KS stone. Optional 6-meter wide motorized screen with AT foil cloth for RGB laser projectors or 6.1-meter Cinemascope LED screen DCI P3. Barco Freya+ projector. ASCENDO Immersive Audio GmbH 17.2.13 Setup with 80 inch infrasonic subwoofer. Over 300 meters of visual LED strips, 200 meters of which can be digitally recorded with video signal. 50 square meters of immersive image extension through LED screen on sides and ceiling. Calibrated acoustics according to RT60 standard. Constant energy distribution (ETC) from 50 Hz with a maximum deviation of 20 ms in the room.
