After years of consulting on various projects, two of my clients posed this question to me for the first time: “What guarantee is there that the acoustics will be right?” My answer, and their reaction to it, was similar to those I got from my dentist when I asked him if he guaranteed the “Painless Dentist” sign hanging on his wall.
“Of course I guarantee it! After we’re done here, I’ll ask you if you felt any pain. Then I’ll ask my assistant if she felt any pain. And then I’ll see if I felt anything and I guarantee the majority of us will be without pain.” Not quite reassuring.
