Have you ever wondered about what you hear at night? If so, you’re not alone. The topic of whether or not our hearing stays on even when our other senses have turned off during sleep has been one of considerable debate.
New research may now be showing that we do, in fact, process auditory information in our sleep. These findings could prove valuable in the future for those who use hearing technology for hearing loss.
Research from Vanderbilt University recently released preliminary results from an EEG study that offered surprising insight into hearing and sleep. In the study, the team worked with a group of preschool-age children at the university’s preschool. The children were placed in a quiet and isolated room for naptime, and while they were asleep, researchers played a group of three nonsense words over a short period. The preschoolers’ brainwaves were tested using an EEG machine.
Following the nap, the team showed the kids a variety of nonsense words, including those played during naptime.
According to the results, the children showed signs of recognition for the naptime nonsense words, confirming the hypothesis that they were still hearing and processing sounds while asleep.
Researchers dig into hearing during sleep
This isn’t the first study to take a closer look at whether or not we process auditory information during sleep, how it happens and how it affects us. It has been a question that has intrigued scientists for years:
As researchers continue to explore how and what we hear while sleeping, experts believe this valuable information not only helps us to understand better how hearing works but may also one day translate into better hearing technology and treatment options for those with hearing loss.
