After spending a while moving the skeleton in a nightclub or singing loudly the great successes of our favorite artist in a concert, does the ears suffer? A new study published in 'Frontiers of Neuroscience' flatly denies it.
As revealed by their research, there is no evidence that permanent changes occur in the audiometric or electrophysiological measures that make it inadvisable to attend an event where music sounds at full speed.
Moreover, as the authors claim, coming from the University of Texas, attending a noisy event does not cause changes in the neuronal function of the brain or in the activity of the sensory hair cells of the inner ear.
The thing reaches such an extreme that even in the case of going to a music festival can talk about a subsequent hearing loss. And that despite the fact that it is the type of events where, according to the authors, the decibels (103-104 dB) rise and more hours are exposed individuals to the high music (up to 16 hours in their experiment).
The only thing they have detected Colleen G. Le Prell and his team is that the day after attending a concert, we are given something worse distinguish words spoken by a caller with background noise than under normal conditions. The good news is that the effect is transient and disappears soon.
It is not the first work that inquires about the effect of concerts on hearing. A few years ago, Australian researchers found that, right after attending a noisy event, we temporarily lost some hearing. However, they also agree that it is not a lasting damage.
What happens is simply that the ears, and especially the cochlea, protect themselves by releasing a hormone called ATP. The hormone binds to a receptor and acts as a protective shield, reducing sensitivity to sound. After several hours, or sometimes more than a whole day, everything returns to normal.
