Trying to get down to a complex report, amidst the mayhem and cacophony of raised voices in conversation and the many animated telephone conversations, the chatter keyboards and printers and whirring of coffee makers and vending machines mixed with the sounds of cars, vans and lorries outside? Is there so much noise and hubbub that you can hardly think? Or does excessive noise at home and outside in the street with dogs barking, cars screeching, horns sounding and kids screaming drive you to distraction? Do you need some quiet to get down to some serious revision at home, yet no one in the family seems to be able to oblige?
