: High-intensity cries from children (especially between 9 months and 6 years) can reach sound pressure levels between 99 and 120 dB(A) . This is loud enough to cause acute discomfort and potentially lead to noise-induced hearing loss for caregivers over long periods. Frequency Profiles :

: A review in Frontiers in Neuroscience explains how laryngeal tension and "roughness" associate directly with a newborn's distress levels. : Fundamental frequencies usually range from 400 to 650 Hz
: Researchers found that screams differ from normal speech not just by volume or pitch, but by a quality called roughness . This refers to rapid changes in volume (between 30 and 150 Hz) that target the amygdala, the brain's fear center, to trigger an immediate alarm response.

The study of "child scream" audio effects generally falls into three categories:
