I don't think you can "explain" to people that you need to concentrate, if you've already told them in ten different ways, then they know what you think you need, and either (1) don't care about your needs, in which case you are doomed, or (2) they see in your actions that you still do your job anyway, so it can't be that bad. The fact is, for most of us, even if we are interrupted, we still
do get the job done. Just not as comfortably or in such detail as we'd like.
I've been through the "explaining" phase of trying to help my spouse, who cares a lot about my ability to do my job, and yet is a prolific interrupter, "get it". It hasn't worked for me. It leads to bitterness and arguments.
The healthy solution: If you need peace and quiet to concentrate, like me, get yourself your own space. Start going to a different room to concentrate, or a co-working space (if you work from home). Depending on your job, you might only need a certain percentage of the day for solid concentration.
