According to the World Health Organisation, noise exposure is the single biggest cause of preventable hearing loss (Sminkey, 2015). Did you know that an improper fit of earplugs may cause an acoustic leak that is not readily visible and can significantly reduce protection levels? Earplugs are a solution only if it forms a seal that ensures that the loud noises only reach the ear through the filter inside the earplug that serves to protect against harmful noise.
