So I’ve been working from home for the last 5 years. Before that I have 13 years of experience sharing a room with people at work; never having my own office. I’m accustomed to people at neighboring desks having basic respect for distracting noise while playing music or watching videos. Now at home, my partner is a RE agent and often works from home as well, conducting phone calls loudly, watching the news etc. I’ve asked, consistently, for the use of headphones so I don’t have to listen to whatever is playing/being spoken of. Hearing training videos or talking news heads is much more distracting than music; but I’d still prefer to not be subjected to the noise pollution of someone else’s neighboring operation. The reaction I get is that I’m asking too much. That my previous body of experience in sharing professional spaces is irrelevant. 

A long time ago I worked in a call center where you sit in long rows of people without so much as a cube wall. Everyone is talking around you, you have to deal. But I’ve moved out of that kind of office operation a long time ago into jobs that require a greater level of focus, concentration, etc. 

Whether it’s business hours or not, I think that people sharing a home have a fundamental consideration of whether or not an audible media is being consumed together, or separately and are behooved to adapt accordingly.

tl;dr I think it’s inconsiderate of others to subject me to audible content they’re listening, but I’m not AITA
