forget the ear plugs
A team of scientists “were able to produce a group of mutant mice whose hearing had been chemically turned down. These, and a group of regular mice, were exposed to noise levels equivalent to those one might experience at the rhythm-music centred events or gatherings popular among the young of the human race.
“In precise terms, this is a noise level of 100 decibels, well able to cause hearing damage. According to the boffins, the mutated mice whose internal volume knobs had been turned down suffered much less hearing damage from the laboratory rave experience than did the unaltered ones.”
