We all know that if a pebble is dropped into water, ring-like ripples spread in all directions over the surface. A doorbell ringing sends out similar but invisible wavelike impulses, which travel through the air with a speed of about 1100 feet per second. Sounds of every kind are transmitted to our ears by just such waves. The modern miracles of sound, motion pictures and radio open up vast sources of entertainment and instruction. To benefit from these, we need our ears, which interpret for us the multitude of sound waves they receive. Lend us your ears and learn about these invisible waves and how our ears are able to convert them into sound.
