I am incredibly fortunate to work in an amazingly well planned and thought out open office and hot desk environment. But even with full focus zones it can be difficult at times to concentrate because of distracting background conversations.
If this happens to you and you are like me and unable to work along to music (I find lyrics way too distracting), you might be interested in trying https://coffitivity.com/. It plays ambient sounds … think library, or cafe (thankfully not whale sounds) to help you block out other noise and focus. I use this app all the time, its a lifesaver.
