I have found that I can focus intensely by wearing headphones while working on my laptop. I listen to non lyric music at https://somafm.com/dronezone/. I have found that this attenuates background noises and speech. I can still hear people talking to me but they tend to leave me alone unless the matter is urgent because I am wearing headphones. I have been doing this since 2005 and have found I get a lot more done with much less stress and the music tends to enhance my thinking, creativity and focus. I use this technique while working and my work is computer based. It's pretty much a soundtrack for working. I also use this technique while walking as it stimulates inner dialog in thinking and problem solving which naturally happens when taking 30 minute health walks. This may not work for everyone but has worked for me in high tech start up environments.
