: A review in Frontiers in Neuroscience explains how laryngeal tension and "roughness" associate directly with a newborn's distress levels.

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

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". Key Scientific Insights from the Research : A review in Frontiers in Neuroscience explains

: 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 : Key Scientific Insights from the Research : High-intensity

: 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.

: Fundamental frequencies usually range from 400 to 650 Hz .
