One of my first thoughts. Further, keep in mind, folks, that the longer the length of exposure (particularly per "session" of exposure), the lower the threshold level of loudness at which permanent damage begins. At some points, I've had managers recommend wearing headphones and playing music to deal with a distracting environment. I wonder whether, were this to be documented, they / the organization could be liable for subsequent hearing loss.
