Technology and Engineering text on sound and acoustics with many illustrations, photographs and drawings to show how to improve acoustics in buildings. This description may be from another edition of this product.
I found this book in my Dad's bookshelf. It was published in 1972. All of the pictures were drawn by hand in ink. (I like the little dog barking.) It is about sound and how it reflecs from walls and other smooth surfaces. You can design buildings that sound good inside, or else they might be too echoey. According to a Google search, Mr. Doelle was a university professor in Canada. I think I want to become a acoustician.
