A studypublishedin the American Medical Association’sJAMA Otolaryngology - Head & Neck Surgeryfinds no growth in child and adolescent auditory modality loss despite a wage increase in headphone and earbud usance .
" Hearing constipation in children is a major public health load given its impact on early speech and language ontogenesis , and afterwards on academic and work force carrying into action later in life , " the authors spell . " Even mild levels of hearing loss have been regain to negatively involve educational outcomes and societal operation . "
As portable medicine participant continue to grow in popularity , parents , Dr. , and researchers have begin to worry that all the music pouring directly into shaver ' ear could be damage their health . It seems a reasonable enough business , andsome studieson American kids ' auditory modality have identified morehearing passing .
To take a closer face , researchers at the University of California - San Francisco take apart information from the National Health and Nutrition Examination Survey ( NHANES ) , garner from 1988 to 2010 . They reviewed record from 7036 kids and teen between the ages of 12 and 19 , checking each participant ’s hearing tests against their exposure to noise .
As require , the authors write , they did find a gradual increase in headphone employment and other " recreational noise exposure . " And they did see an uptick in hearing loss from 1988 to 2008 from 17 percent to 22.5 percentage . But after that , the trend seemed to invert , drop all the way down to 15.2 percentage — lower than 1988 levels . They also bump no pregnant relationship between interference exposure andhearing loss .
The results were not uniform ; some groups of kids were worsened off than others . player who identified as nonwhite , and those of lower socioeconomic status , were more potential to have hear problems , but the researchers ca n’t say for sure why that is . " Ongoing monitoring of hearing loss in this universe is necessary , " they drop a line , " to elucidate long - term course and name butt for interference . "
Before you go wild blasting euphony , we should mention that this survey has some major limit . Hearing red ink and other data points were not measured the same way through the entire data assemblage full point . Participants had to self - account things like hear loss and health care use — elements that are routinely under - reported in surveys . As with just about any wellness research , more studies are still postulate to reassert these finding .
