Acerca de este recurso...

Sounds, whether from talking, music, an earthquake, a fire or a sonic boom, travel in waves. Wave travel, called propagation, has a different velocity through each material, like water or air.Frequency is the number of times an event occurs per unit of time. For sound, the frequency is measured in Hertz, abbreviated Hz, which means is period cycle, from the top of one wave to another, per second. Humans can normally hear anywhere from 20Hz to 20000Hz, while dogs can hear up to 60,000 Hz, and some bats can hear sound as low as 1 Hz. Sound is perceived in pitch; higher frequencies sound like higher pitches (like a whistle) and lower frequencies have lower pitches (like a tuba).
