Three groups of female albino guinea pigs were given caffeine, audio or both
A new study has revealed that drinking caffeine the day after a concert could be bad for your hearing.
Published by JAMA Otolaryngol Head Neck Surgery and conducted at the McGill University Auditory Sciences Laboratory, the study exposed three groups of female albino guinea pigs to either caffeine, 110 decibel “pure tone sound” or both.
As Consequence Of Sound reports, the group that were exposed to both caffeine and sound recovered their hearing significantly slower than those who were given just sound.
On day eight of the 15-day study, the group of guinea pigs just listening to audio almost fully recovered their hearing, except for that within the 20kHZ range. The group with caffeine and audio had issues regaining their hearing in the eight, 16 and 25kHz frequencies, and this only got worse after day 15.
Concerts typically measure at between 100 and 120 decibels in sound, with the study pitching its noise levels in the middle of that range.
