Listening to a Three-Dimensional Virtual Reality Sound: Effects on Stress Response of Adults.
Article in Brain and behavior, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
introductionVirtual reality (VR) technologies utilizing three-dimensional (3D) sound may offer sensually engaging imitations. Thus, they may lead to relaxation or may provide a way of escaping from disturbing life events. As they have the potential to manage stress, the current study aimed to investigate the effects of VR 3D sounds on the stress axes of the body, namely the autonomic nervous system (ANS) and hypothalamo-pituitary-adrenal (HPA).
methodsParticipants (19 men and 27 women, mean age 25.8 ± 10.4 years), wearing on-ear headphones, did not listen to anything (control) or listened to a mono or 3D sound imitating a real-life situation taking place in a virtual barbershop. The control phase was immediately followed by mono or 3D phases. Half of the participants in mono and 3D phases were crossed, with 45 min intervals, to control the effect of time and habituation. Reactivity of ANS and HPA was measured by heart rate variability (HRV) and salivary cortisol measurements, respectively. HRV was measured during each phase by a 5-min continuous electrocardiogram recording. Salivary samples were taken during control recording and 15-min after mono or 3D sound listening. HRV parameters consisted of both time- and frequency-domain parameters, including standard deviation of R-R interval (SDNN), total power (TP), and low frequency/high frequency (LF/HF), as a measure for sympathovagal activity.
resultsCompared to the control phase, the 3D sound increased almost all HRV parameters (including SDNN, TP, LF/HF, etc., p < 0.05) but did not affect salivary cortisol levels (p > 0.05). Effects of mono sound were in between the control and 3D sound phases.
conclusionIt seems that a 3D sound imitating a real-life environment does not affect HPA but increases HRV and sympathovagal balance, suggesting that VR 3D sound is likely to reproduce an ANS response observed in real life.
