concentrated in open-plan office to work is not always possible. On one side of the shopping with its places quite loud calls, on the other colleagues who loudly talk about the last weekend. Earplugs are there not always sufficient to the hide, with the sprinkling by the Bach smoking I have found the solution for me. The "title" is 1h long and consistently the same sound, it does not vary in my opinion. This makes it directs itself not from, I hear it after a few seconds no longer conscious. Only it can happen that you have to by the sound of running water to the toilet rather ;-). I let all the repeat run, therefore would have a length of 5min been enough (wg. Of storage space). I can only recommend, finally relaxed working possible, without noise through chattering colleagues.
