Investigations of the Effect of 3D Bioacoustic Signals Reproduced in a VR Room on Patients in a Geriatric Ward of a Hospital

Abstract

The positive effects that bioacoustic environments in nature can have on people raise the question of the extent to which bioacoustic recordings can have positive effects as well when played back via VR in the context of a hospital. This paper presents a study in which the effect of a 3D soundscape recording including a 360° still image on geriatric patients in a clinic was investigated. 28 test subjects each spent 15 minutes in a 360° VR room, surrounded by six projection screens and 14 loudspeakers. The study was conducted in a geriatric rehabilitation ward. The recording location was chosen in a nearby recreation and nature reserve. The subjects' state of mind was measured at four points in time using a standardised psychological measurement procedure. During the 15-minute stay in the virtual nature, biosignals of various vital parameters were recorded. In addition, the room was opened to patients and staff at defined times and their use was recorded. The staff were asked about their experiences. The results show that playback increased the well-being of most participants. The therapeutic possibilities of using 3D bioacoustic recordings are discussed and future research and application scenarios for the system are presented.
