THE SOUND

What is the full meaning of sound?




The sound that we hear is from the tool that makes the sound. For example: bells and gongs that are struck, guitar strings that are plucked, and from other musical instruments that make sounds. All of these can be referred to as sound sources.

Here are some things and facts about sound:

1. The Definition
  • Sound is produced by a vibrating object
  • Sound sources are objects or tools that can emit sound
  • This back and forth motion is called vibration
  • Strong vibrations make a loud sound, weak vibrations make a weak sound Fast vibrations make a high sound and slow vibrations make a low sound
  • The sound we make we call sound
  • Our voice is generated in the vocal cavity
  • The vocal cavity has vocal cords. When the vocal cords vibrate, sound is produced. The vocal cords are vibrated by the air, by our breath.
  • The pitch of the voice is regulated by the muscles around the vocal cords
  • Everyone's voice color is different. This difference is caused by differences in the shape of the mouth, the shape of the throat, the shape of the nose, the shape of the teeth, and so on.
  • The equilibrium position is the position when it is not vibrating.
  • Waves are actually vibrations that propagate.
  • Transverse waves have a direction perpendicular to the direction of propagation.
  • Longitudinal waves are waves whose direction is in the direction of propagation.

2. Sound Propagation
  • Sound takes time to propagate
  • Sound travels through solids, liquids and air
  • The pitch of the sound produced is determined by the type of vibrating source
  • Amplitude is the greatest deviation of a vibration from its rest position.
  • The sound strength is very dependent on the amplitude of the vibration
  • The number of vibrations made in one second is known as the vibration frequency.
  • The high and low sound depends on the frequency of the sound.
  • Humans can only hear sounds with a frequency between 20 and 20,000 vibrations per second

3. Reflection And Sound Absorption
  • Whether or not an object reflects and absorbs sound depends on its surface
  • Reflected sound that sounds almost simultaneously with the original is called an echo.
  • The reflected sound that is heard after one word of the original sound has been uttered is called an echo
  • Soft surfaces are difficult to reflect sound.
  • Hard surfaces reflect sound
  • Sounds with a frequency of less than 20 vibrations per second are called infrasonic
  • Sound with an frequency of more than 20,000 vibrations per second is called ultrasonic
  • There are animals that can hear ultrasonic sound
  • Various objects vibrate with the source of the sound. Events follow the vibrating object is called resonance.
  • Many instruments are amplified by resonance.
  • Tone is a sound that is frequently regular.
  • The sound sources of musical instruments are in the form of rods, strings, air cavities and membranes.
  • When the sound source is closer, the sound emitted is louder.
  • When the sound source is far away, the sound sounds lower.

Summary:
  • Sound sources are objects or tools that can emit sound.
  • Vibration is vibration back and forth about the equilibrium position
  • The equilibrium position is the position when it is not vibrating.
  • Waves are vibrations that propagate.
  • A transverse wave is a wave whose deviation direction is in the same direction as the direction of propagation.
  • Longitudinal waves are waves whose deviation direction is in the same direction as their propagation.
  • Sound takes time to propagate.
  • Sound travels through solids, liquids and gases.
  • The speed of sound propagating through a substance depends on the substance through which it passes.
  • Amplitude is the greatest deviation of a vibration from its rest position.
  • The strength of a sound is very dependent on the amplitude of the vibration.
  • Vibration is a back and forth movement towards an equilibrium position.
  • Vibration time or vibration period is the time required to make one vibration.
  • The frequency of vibrations is the number of vibrations that are made in one second.
  • The high and low sound depends on the frequency of the sound.
  • Humans can only hear sounds of certain frequencies.
  • Sounds under sound or infrasonic are sounds with a frequency of less than 20 vibrations per second.
  • The color of the sound depends on the shape of the sound source.
  • Sound of sound or ultrasonic is a sound with a frequency of more than 20,000 vibrations per second.
  • Reverberation is a reflected sound that is heard almost simultaneously with the original sound.
  • Resonance is a vibrating event of an object with the same frequency
  • The Doppler principle states that when a sound source is moving closer, the sound is heard rising and when the sound source is moving away, the sound is getting lower.
