In this paper we present a pilot study on the prospects of working with dynamic sound intervention that adapts to physiological data. The study concerns an investigation of whether dynamic synth-based soundscape compositions, that adapt in tempo to the heart rate of a user, can lower and stabilize the heart rate faster than a 60 beats per minute (BPM) static synth-based soundscape composition. The assumption of the dynamic soundscapes is that if the tempo constantly decreases with either an adaptation of 10% or 2% below the actual heart rate, this will aid in bringing the user from a stressed to a more relaxed state (after 1 minute of physical/psychological exercise). To test the assumption, we included 46 test subjects in a repeated measures test with four different conditions of silence, static, and two variations of dynamic sound stimuli. The study furthermore includes short interviews on how the test subjects experienced the different conditions. Using the velocity of the decreasing heart rate as a measure, the influence of the four different conditions was estimated. The study cannot present any results of statistical significance between how fast the static and dynamic soundscapes decrease the heart rate. Qualitative insights from the interviews reveal how a majority of the test subjects found the characteristics of the soundscape composition relaxing and comfortable, while more varied responses were found in assessing the composition as exciting, boring, and vibrant. The paper discusses the findings and presents critical thoughts on what could be considered in a further development of a concept like this. Even though the study cannot reject the null hypothesis, the paper brings a new perspective to the area of working with sound intervention in health.
