Adaptability of Baroreflexsensitivity and Heart Rate Variability to Noise and Mental Stress

Purpose: Spontaneus barorezeptor reflex sensitivity (BRS) and heart rate variability (HRV) are well established methods to detect autonomic dysfunction. The objective of this study was to evaluate the effects of different noise exposure and mental stress on the autonomic nervous system and the role of the short- term cardiovascular regulation. Methods: Spontaneus baroreflexsensitivity and heart rate variability was measured at rest and given stress with different noise (pink noise, airplane noise) at intensity Leq 80 dB(A) and 90 dB(A) in experimental conditions. The study group consisted of twenty healthy normo…
