Sound is produced,“When the key is pressed down, it raises the wippen, which forces up the jack against the hammer and lifts the lever. Simultaneously, the key also raises the damper and immediately after striking the string, the hammer drops back, allowing the wire to sound. When releasing the key, the damper drops onto the wire at the acceleration of gravity, 9.8 m/s2, cutting off the sound. The role of levers is to transmit the movement of the fingertip to the hammer that strikes the string. The harder the pianist presses the key, the louder the pitch of the sound is“ (K.)
Everyone has seen a piano. Everyone has heard a piano. But many people do not know the physics behind a piano. In this Glog you will learn how the piano produces the music and how sound waves travel to you ear and your ear vibrates to a certain pitch. It may seem complicated, but don't worry it's easier than it sounds.
When a note is hit, it compresses and sends pulses of compressed air to your ear. Each piano key also has a natural frequency, a frequency at which an elastic object once energized will vibrate, and when you strike the key will vibrate at a certain frequency that will hit your ears and you hear a note.
