Toys that move flexibly, feature bright colors, and make sounds tend to capture babies' attention more easily. However, pay attention to whether your baby's toys are too loud. Experts point out that excessively noisy toys may contribute to reduced cognitive development in children.
Parents Beware: Loud Toys May Hinder Child Development (Public Health Network)
Medical experts discovered through tests measuring children's letter-matching and number-memory abilities that toy noise increases children's distress levels, leading to auditory fatigue.
At noise levels reaching 65 decibels, children's motor precision, short-term memory, cognitive abilities, and comprehension all decline. Noise transmits through auditory organs to the cerebral cortex and autonomic nervous system, triggering a series of adverse reactions in the central nervous system.
This study indicates prolonged exposure to noise environments can cause symptoms like tinnitus, dizziness, insomnia, vivid dreams, and delayed reactions to soft calls. More severe effects include palpitations, auditory hallucinations, head pressure, and ear itching. Children in developmental stages possess more sensitive and delicate sensory and nervous systems, making them particularly vulnerable to noise harm.
