Had the same problem. Not just me, all sw engineers, but it was more of a problem for the ones that actually were working on bigger projects involving a lot of coding. A coworker tried using an availability light but.. good luck trying to get people to respect it. Either people will miss it, forget it, or ignore it (specially if they are above you on the org chart). I tried mufflers a few times, but it didn't work that well. Same issue as availability light, plus the fact that everyone looks weirdly at you and initiate conversations when you have the mufflers on.. So what I did was push working from home more and more until I went to working 1-2 days from the office per week. Now I have a much better productivity, ability to focus throughout the day, etc, besides all the advantages of not having to commute 5 days per week.
