The company I work for (large manufacturing/engineering) has subscribed to a Muzak service and plays a mixture of soft rock, pop, and country music all day long in our building. While the music selection is designed to be as inane as possible, I still find it distracting. Neither am I unique from the other developers on my team: we all find it irritating at worst and distracting at best. It should be clear that we all listen to music of our choosing at times with personal headphones, but we like the option of making the choice when to do so.
So I wonder:
a) Is there anyone else whose company insists on playing any music for all employees without respite during the workday?
b) Is there any evidence that we can provide to show that this is distracting and likely to reduce productivity for people whose jobs require a degree of concentration and mental effort? So far I can point to the following:
Joel Spolsky has some pertinent essays The Development Abstraction Layer and A Field Guide to Developers.
The book Peopleware documents a study comparing good and bad performers based on environmental conditions in chapter 8.
Please let me know of any other anecdotal or statistical or study related data that I can use to make my case. If you think this is not worth the attention or effort, I'd be interested to hear why from that angle as well.
