Your volume is waaay too loud
The high-tech devices we're plugging into don't max out until around 115 decibels -- which, to put into perspective, is just slightly quieter than a jackhammer. (Your car stereo, by the way, can reach 154 decibels.) It's tempting to turn your volume all the way up when you've got a particularly good jam on, but according to Dr. Cherukuri, keeping your volume that loud can cause permanent hearing loss in as little as 15 minutes. "If you cannot carry on a conversation with someone 3ft away from you in a normal voice while listening to your music or a podcast, IT IS TOO LOUD,” Dr. Cherukuri says.
Losing your hearing doesn't just suck, it can ruin your life
By the way, you’re not just threatening your aural prowess by cranking Daft Punk on the subway platform, but a whole lot more. "Leaving hearing loss untreated can have significant consequences, from poorer performance at work, a strain on relationships, a higher risk of heart disease, balance problems, and even a higher risk of dementia."
