We had earlier seen popular book on sound titled Physics and Music by Anfilov, in this post we see another popular science book on sound. The title of the book is Sounds We Cannot Hear by Kundryavtsev.

This is a book in which many aspects of ultrasound are discussed with lot of applications. This comes from era of 1950s when the general optimism about science was very high. Interesting this book answers some questions pertaining to daily life also. For example it has a section on Why Transformers Hum?
The book was translated from the Russian by David Sobolev and was
designed by N. Grishin. The book was published by the Foreign
Languages Publishing House in 1958.
