A lot of people (in this thread, CEO of my company) say "just wear headphones". Noise should be opt in; not opt out. Recently all of marketing went to a conference for a few days; the difference in the quality and quantity of work done was noticeable...
That's a great way of putting it.
One of my pet peeves is along a similar line. I have a quiet voice. When I was younger, I had a quieter voice. The change happened because people were happy to ask me to repeat myself or, in a more blunt way, that I need to speak up. That's fine, it's my problem, it's me failing to communicate properly, and I've learned to be loud enough most of the time because of it.
But it doesn't happen the other way. It's not 'OK' to tell someone they talk too loudly. You can try, and they may temporarily adjust (while, actually, thinking it's your problem) but they won't change their voice for good, like I had to.
If it's a failure of communication for me to be heard by the person stood next to me, it should also be a failure for a person talking to someone at the same distance if I can hear them on the other side of a busy office or a train carriage. And if someone has a bassy vocal fry that penetrates walls, they should raise their pitch. I don't want to have to opt out of their conversation and, if I do, I have to be confrontational.
