A new study by Ghent University researchers shows loud music at festivals can cause hidden, lasting hearing damage. This condition, known as cochlear synaptopathy, affects tiny nerve connections in the inner ear without dropping hearing sensitivity on usual tests. "Our study aimed to identify subtle, early-stage forms of noise-related hearing damage," said Dr. Nele De Poortere. Hidden hearing loss causes trouble understanding speech in noisy places even when hearing tests look normal. Experts explain it’s like signal interference rather than simple volume loss. Using personal sound trackers at concerts, researchers found many attendees experienced muffled hearing. Those who regularly used ear protection had much better hearing over time. Experts warn noise levels at Indian events often exceed safe limits, risking permanent damage. "Many people notice hearing problems only in noisy settings," said Aravindakshan Parthasarathy from the University of Pittsburgh. Early detection tools and stronger prevention efforts are needed, especially for young people. This research stresses the value of hearing protection and awareness to avoid silent damage from loud sounds.
