Differences in the course of physiological functions and in subjective evaluations in connection with listening to the sound of a chainsaw, and to the sounds of a forest

The data relate to a manuscript that will be published in Frontiers in Psychology. Frontiers Media S.A. doi: 10.3389/fpsyg.2022.775173
Names of variables:
Sound: 1 = forest; 2 = chainsaw
ID: the numerical identification of examined person (EP)
AbR: abdominal respiration
ThR: thoracic respiration
AbRR or ThRR - respiratory rate
AbVTR or ThVTR: relative tidal volume change
SCL: skin conductance level
FT: finger skin temperature
BVP: blood volume pulse
BVPA: blood volume pulse amplitude
HR: heart rate
RRit: R-R interval trends
Alpha: peak alpha frequency HRV
Peak HF: peak high-frequency HRV
ASD: absolute values of standard deviations. Example AbRASD: absolute values of standard deviations of abdominal respiration
HRV_nosignif - other not significant heart rate variability parameters; from ibi...to rLFHF_B
We defined 4 time sections for the statistical comparison of differences among the average values of sounds. Periods, defined in MANOVA as a covariate, were not fixed but determined according to literary sources and similar findings from the line charts.
Period1: a control period, 10 s before turning on the sounds.
Period2: from 0 to 79 s
Period3: from 80 s to 209 s (up to 3 ½ min), lasting 130 s (ca. 2 minutes).
Period4: from 210 s to 390 s (up to 6 ½ min), lasting 180 s (3 minutes).
(Sounds) Evaluation:
AS - activation scale
VAS - visual analogue scale
In the AS method, one of ten polarity statements are selected on a scale from 1 to 11. In the VAS method, the respondent ticks his/her current mental and physical state “intuitively” on the line (encodable on a scale 0 – 200 mm).
ASpre, VASpre - prior to the exposure of acoustic stimuli
ASpost, VASpost - after the exposure of acoustic stimuli
