: 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

: 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 : : Researchers found that screams differ from normal

: Fundamental frequencies usually range from 400 to 650 Hz . This is loud enough to cause acute discomfort

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

: Research available on PubMed examines how unique cry melodies can act as markers for neurological health in infants.

If you are looking for a high-quality academic source on the "audio effect" of a child's scream (how it is structured and why it affects us), the most relevant paper is the 2015 study published in titled "Human Screams Occupy a Privileged Niche in the Communication Soundscape," which explores an acoustic property called "roughness".
