Sound Attenuation

Meaning

Sound Attenuation refers to the process of reducing the intensity of environmental noise reaching the inner ear and the central nervous system, a critical factor in optimizing sleep quality and mitigating chronic stress responses. In the context of hormonal health, effective sound attenuation is necessary to prevent acoustic arousal and sympathetic nervous system activation, which can disrupt the nocturnal secretion patterns of restorative hormones like melatonin and growth hormone. This environmental control is a foundational component of clinical sleep hygiene recommendations.
