It is louder than "the cockpit of my jet," said J. Scot Heathman, an Air Force pilot, in a video probing the issue that he posted on his blog under the headline "Potato Chip Technology That Destroys Your Hearing." Mr. Heathman tested the loudness using a RadioShack sound meter. He squeezed the bag and recorded a 95 decibel level.

95 decibels is loud enough that you have to be concerned about hearing loss.

Prolonged exposure to sounds louder than 85 decibels can damage your hearing.
Sixty decibels is equal to the sound of normal conversation, 90 decibels is closer to a lawn mower or hair dryer, and 120 decibels is more like a siren on an emergency vehicle.

From what distance away? Because I had them, and I promise they weren't as loud from normal use distance than a jet engine. Maybe if your ear/microphone is basically touching the bag, but your ear isn't normally that close. Plus, exposure time is pretty significant factor for hearing loss. Rolling up a chip bag once every couple of days when you have chips isn't going to cause hearing loss.

Rolling up a chip bag once every couple of days when you have chips isn’t going to cause hearing loss.

Go look up a video of these bags. Mere handling them is loud as shit. Not just when you roll them up when you're done.

NIOSH standards say that at 95db, you shouldn't be exposed to more than ~45 minutes of it. Where-as an alternative "loud" bag was 77 db, which is longer than 50 hours of exposure (exceeds the rolling period and is thus "safe").

Noise exposure is additive during a rolling period. So just saying "once every few days" is bullshit. This isn't something that happens or can be in a vacuum. It's adding to the total exposure that you're exposed to every day. On top of the rest of your day the 95db chip bag is a really stupid fucking way to damage your hearing. Because you chose to eat some chips while watching a movie one night.

As someone with tinnitus... Fuck people who downplay hearing loss/damage. You should be doing everything possible to keep your exposure to anything above 80db to a minimum.
