Sound

This practical book answers common questions about sound by looking at evidence and demonstrating its properties through a range of carefully chosen experiments that can be done in the classroom or at home.

It covers such questions as 'What makes sound?', 'How does sound travel?', 'How do we hear?', Why are some sounds louder than others?', 'What makes things sound different from each other?' and 'How do microphones work?'.

It also includes questions for readers to investigate further on their own.

Written by a highly experienced and acclaimed science writer, the book includes links to useful websites as well as glossary, index and list of further reading.
