LIVING IN AN IRISH estate with more than 100 cars that live uphill from us means we listen to the footprints of those vehicles as they trundle in and out of the estate. Some are louder than others. They wake us up and they force me to revise audio work that I try to do in the street-facing office space I use. Some day, we will regain the quiet little bubble that we enjoyed when we first moved into Cashel. And if we don't, we'll move to a place where that sound cushion is impenetrable.
