Anyone who has worked in an office can relate to the many distractions fellow colleagues can produce. From loud conversations to pungent wafts of lunch foods, coworkers are often real roadblocks to productivity (you might even be experiencing it at your desk right now). Indeed, a study from researchers at the University of Sydney found that office noise was cited as the most frustrating aspect of the work environment by about 50 percent of employees in open offices. What's more, Oxford Economics—an independent global advisory firm—found that 53 percent of office employees complain that workplace noise reduces their satisfaction and productivity.
