: 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 can review these peer-reviewed sources: efect_audio_tipat_de_copil

The study of "child scream" audio effects generally falls into three categories: : Researchers found that screams differ from normal

: Fundamental frequencies usually range from 400 to 650 Hz . the brain's fear center

: A study in Nature Scientific Reports discusses how neural networks unravel these acoustic features to predict developmental traits.
