Julian Treasure, chair of Sound Agency, a firm that advises business on how to use sound, presented a talk at the TED conference in June. He talks about how poor sound environments affect our ability to work, to learn and even how noisy environments can affect our health — he cites an example of an increase risk of heart attack to teachers working in noisy classrooms. Treasure's wish is that architects would take greater heed of the acoustic impact of their designs, all forming part of what Treasure calls 'invisible architecture'.
