For a few hour after a particularly loud concert , the sonorousness in your ear make it elusive to take heed . When your friend ask how the show was , you sheepishly ask them speak up so you may get what they ’re saying . This hearing red ink , which is most often reversible , does n’t mean you ’re more likely to need a sense of hearing aid afterward in life . In fact , researchers found the diametric — reversible hearing passing actuallyprotectsyour ears .
research worker take by Gary Housley , chair of physiology at the University of New South Wales in Australia , exposed mice to gaudy noise to ascertain more about how two-sided sense of hearing passing work . Some of the shiner had unconstipated capitulum , but others had ears that lacked a sensory receptor that accepts ATP , a chemical substance that the cochlea — the spiral shaped auditory part of the internal ear — vent .
The mice without the receptor could hear to loud noises for hours on end without experiencing any short - term burden . It was almost as if they could not comprehend a variety in legal levels . The mouse with the regular ears , however , experienced forgetful - term hearing going that could last for more than 24 hours , but in the tenacious trial protected their ear . And even though the mice without the sense organ did n’t seem to notice booming noises , they showed more evidence of permanent hearing loss .
" It ’s like sun exposure , " says Housley . " It ’s not the acuate exposure , but the chronic exposure , that can cause job years later . "
This paper , publish in the Proceedings of the National Academy of Sciences ( PNAS ) , reenforce what Housley discovered in a old study about hearing loss . In that study he looked at two Formosan family with a mutation in their ATP receptors ; if family appendage worked around loud noises , they go through accelerated hear going .
" Because our see sensitiveness adapts , we can withstand loud noise , but we ca n’t sense the right-down saturation of the sound and if we go past the secure sound upper limit , we will damage our earshot — despite this protective version mechanism we have discovered , ” Housley suppose .
