 When an object vibrates, it produces sound. Sound is divided into ultrasonic, audible, and infrasonic frequencies based on the vibration frequency per unit time. Human hearing is within the range of 2000 to 20000 hertz. Within this range, there are many different frequencies of sound, which are similar to tuning a radio station.
DO RE MI FA SO LA SI are the same. The more things you put in a cup, the heavier it feels, the slower it vibrates, and the lower it sounds. Conversely, the clearer and brighter it sounds, the higher the pitch.
Open the piano, the cymbal, the aluminum plate, the guitar is the same, the high-pitched strings are thin, the low-pitched strings are thick, because their vibration frequencies are different.
Principles and Inquiry:
1. The pitch of a sound depends on the vibration frequency of the sound source – the number of times an object completes a periodic vibration within one second. Its unit is Hertz (HZ). One Hertz is one vibration per second. The faster or higher the vibration frequency of an object, the higher the pitch of the sound. The slower or lower the vibration frequency of an object, the lower the pitch of the sound.
2. The more air in the test tube, the lower the pitch. The less air in the test tube, the higher the pitch.
3. When we strike different test tubes, the pitch of the sound produced is different, resulting in a variety of musical bottles with different tones.
