It's always been a mystery why the maximum speed limit in most countries is 75 mph, yet automakers build cars that can go 120 mph or better. The same concept applies to personal music devices that can crank out 130+ decibels when the limit for hearing damage is around 85. Now trends point to limiting sound pressure output of headphones to the 85 decibel levels. Don't people have the right to speed and destroy their hearing as they please? Does limiting sound output to protect hearing violate your idea of personal freedom or is it a common sense design feature that should have been implemented from the beginning?
