Despite the convenience of noise-canceling earbuds and headphones for creating a quiet environment, experts are warning about potential dangers to health. The growing popularity of such devices, particularly for blocking out background noise or distractions, can pose risks as they can potentially mask crucial sounds, according to Josh Gordon from the Singapore technology company Geonode.
High-quality noise-canceling headphones can reduce sound by 20 to 40 decibels, however, this can make users less aware of their surroundings, resulting in potential risks. In addition, excessive wearing can impact hearing and create auditory processing challenges, says Dr. Ruth Reisman, a New York-based clinical audiologist.
California-based audio expert, Joel Smith, concurs, explaining that misuse of these headphones can cause hearing loss, tinnitus, and difficulty distinguishing sounds clearly when the volume is too loud for too long. A decrease in speech interpretation and other subtle sounds can occur as the inner ear hair cells deteriorate from loud noise, leading to a potential auditory processing disorder. The earbuds can also pose a risk of ear infections if not cleaned regularly, as they can trap moisture and bacteria.
Despite these risks, experts agree on beneficial applications of noise-canceling headphones, particularly for people with sensitivity to sound or autism. They agree that the devices are safe for use at moderate volume and for limited periods. Reisman suggests a safe volume below 80 decibels and usage limited to two to three hours daily. Regular cleaning and balance factors must also be considered. For safe usage, Smith advises following the 60/60 rule, which is keeping the volume at 60% or less and taking breaks every 60 minutes. They urge cautious use especially in loud environments, regular breaks, and moderate volumes for auditory health maintenance, stating that like any tool, awareness of its limitations and responsible use is key to safety.
