La ciencia del sonido

How does a phone actually work? What are ultrasounds and how do they form an image? Why does your voice sometimes sound strange to you? The book-box The science of sound discovers in a playful and didactic way how sound is created, heard and works. A solid foundation in scientific principles is provided in full color through this interactive exploration of sound, as well as many simple and fun activities and experiments to do at home. Includes materials to build six machines designed by expert paper engineer Rob Ives that help children discover the science of sound through experimentation.
