Noise was considered an environmental stressor causing a wide range of health effects such as acoustic, cardiovascular, nervous, and endocrine systems. The present study was performed to examine the effects of a repeated noise exposure on adrenal gland and heart tissue. The results showed that exposure to moderate intensity sound (70 dB[A]) causes time-dependent changes in the morphological structure of the adrenal cortex that involve disarrangement of cells and modification in thickness of the different layers of the adrenal gland. The experiment revealed important changes depending on exposure duration in the morphological structure of heart tissue that causes irreversible cell damage leading to cell death or necrosis.
