Abstract

The relationship between the auditory system and cardiovascular system has as basis the incidence of hypertension in about 20% of subjects with auditory deficit. Exposure to music at high intensities chronically through the ear phone contributes to the development of hearing loss. The classical music presents as characteristic effect activation of the parasympathetic nervous system and reduction of the sympathetic nervous system activity, besides heart rate reduction. The heart rate variability (HRV) is a well known method in the literature that analyzes the cardiac autonomic regulation. However, the literature is not clear whether exposure to different styles of music, as well as the intensity and duration of exposure to music with ear phones may affect the cardiac autonomic regulation. Objective: To evaluate the effects of different styles, intensities and duration of exposure to sound stimuli on heart rate variability. Method: The study will be conducted in young adults of both genders from 18 to 25 years old. All individuals will go through an audiological evaluation to be confirmed the healthy state of the auditory system. We will analyze the linear, nonlinear and geometric indices of the HRV. The evaluation protocol will be based on the record to stand for 20 minutes. In this initial period the individual will remain with the headset off. After 20 minutes of initial registration, the individual will be exposed to classical music and heavy metal music for 10 minutes in each musical style. The sequence of exposure to different musical styles will be random from individual to individual. To analyze the effects of the exposure period to the sound stimulus, indices of HRV will be evaluated during 5, 10, 20 and 30 minutes of exposure. Association between the intensities of sound stimuli and the HRV indices will be performed through the correlation between the intensities of the stimuli (dB) and the values of each index. In this protocol the subjects will be exposed to music during five minutes every intensity of music. (AU)
