Is there any equipment to prevent external sound in an office environment?

Question

My office have worldspace on speakers. I like music very much and my concentration is only on music not in my work.

Answer 1

Well, you go to office to work, not enjoy music only! What about using ear phones? In that case, every person has access to music or no general disturbing sound if silence is preferred.

In an enclosed space the best way to stop unwanted sounds is to use sound-absorbent mufflers. Ideally, these should have been installed while designing and constructing the office interior. Your office can redo the interiors again, if necessary selectively, and install them. The sound-absorbent materials come in different qualities and with different installation requirements. You will need professional help to do it the right way.
