How can noise-cancelling headphones contribute to hearing loss?

According to a new study by audiologists from the UK's National Health Services, noise-cancelling headphones may put users at risk of hearing loss through mechanisms related to brain processing. The increasing use of these devices is leading to a rise in hearing issues that are triggered by the brain rather than direct physical damage to the ear. These headphones, by providing enhanced sound clarity without background noise, may inadvertently cause the brain to process audio signals differently over time, potentially resulting in auditory processing disorders. This risk appears to be particularly concerning among younger users who use these devices extensively.
