Yes. It is somehow at times comforting to hear humans speaking, even if they are not choosing to speak to me.
These days society seems to be run by extroverts, for extroverts, and little if any regard is given to introverts.
I think it's always been like that, and these days we're starting to recognize that introversion isn't a deficiency, it's just how some people are wired (and doesn't necessarily equate to "shy" or "awkward")
Oh sure, I'll just meet with HR and Facilities to rearrange the 100-cube farm so people are in rooms when they feel like talking.</sarcasm>
In a small company, this might work, but you're probably missing out if you don't hear the conversation. If your group is big enough that the conversation doesn't relate to you, or isn't important to you, then it's usually big enough that you're powerless to change it.
If people feel the need to hear "café noise", maybe it's just a sign of loneliness?
And if you need white/pink/whatever-noise, maybe your office should integrate some noise policies or try to reduce noise by giving offices to small teams of people.
I get that people use those audio streams and soundfiles to "shut off distractions", but to me, this is only a fix to a bigger problem.
Edit: Maybe someone should start beerbarsound.com, so you feel like you're out drinking with your friends, but in reality you're sitting at home/the office, working, without any friends.
