: 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. For a deep dive into these effects, you
: 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.
