NEW YORK, NY, USA, February 6, 2023 / -- The team behind audio science book What’s my Frequency? is thrilled to announce the launch of the second children’s book in the Wave Science for Kids series, What’s my Amplitude?

What’s my Amplitude? explains how heights of sound waves affect how loud or soft sound can be (i.e. the amplitude) in a way both readers and listeners will love. The story centers around various musical instruments, and becomes a fun read-aloud experience for adults and children alike. The sound waves create harmony as readers learn about the camaraderie and creative potential that can happen when friends work together to solve a problem.

Early reviews from educators sing the book’s praises:

“What's my Amplitude? is a fantastic introduction to acoustic science for kids! The author cleverly illustrates basic sound composition in an interactive, easy to understand way. This book sneaks the vegetables in with the sweets and I’ve had so much fun using it to teach my own young students about the fundamentals of music," - Brian Wiseman, Musician and Vocal Coach.

According to the American Academy of Pediatrics, even before infants are able to speak, they can benefit from story time with language acquisition and literary skills. The team behind the Wave Science for Kids series encourages parents, educators, and caregivers to incorporate What's my Amplitude? onto their children's reading list to promote a love of science through reading.

“We aim to inspire the next generation of scientists and help them discover the sounds all around them. Whether in an orchestra or in a lab, we believe the science of sound is something almost every child can relate to.” said author Teju Prasad.
