If you ’re have trouble hearing in a noisy situation , you might want to rick your head . New research finds that citizenry of all ages depend more on their right capitulum than their left , and think of selective information better if it comes through their right capitulum . The findings werepresentedat the one-year meeting of the Acoustical Society of America in New Orleans on December 6 .
Kids ’ ears work differently than adults ' do . former study have found that children ’s auditory systems ca n’t separate and process information coming through both of their ears at the same meter , and rely more on the auditory tract derive from the right wing . This reliance on the right auricle tends to decrease when kids hand their teen , but the findings paint a picture that in certain state of affairs , correct - capitulum ascendence persists long into adulthood .
To study how we process information through both our ears , Auburn University audiologists bring 41 grownup subject ( between the eld of 19 and 28 ) into the lab to nail dichotic listening tests , which involve listening to unlike auditory inputs in each ear . They were either presuppose to pay aid only to the words , judgment of conviction , or numbers they get wind in one ear while disregard the other , or they were asked to repeat all the words they heard in both ear . In this case , the researchers easy upped the figure of particular the run subjects were asked to remember during each hearing trial run .
They find oneself that the harder the memory tests get , the more performance depart between the ear . While both ears performed equally when multitude were necessitate to commemorate only four or so words , when the identification number receive higher , the deviation between their ability became more patent . When asked to only focus on information amount through their right ear , people ’s performance on the memory task increased by an average of 8 per centum . For some people , the result was even more dramatic — one person perform 40 percent well while listening with only their right ear .
" schematic enquiry shows that correct - spike advantage diminish around age 13 , but our results point this is related to the need of the task , ” one of the research worker , assistant prof Aurora Weaver , explained in apress release . In other words , when the going gets tough , the right ear steps up .
