What part of a musical instrument amplifies sound waves?
What part of a musical instrument amplifies sound waves?
On a stringed instrument, such as a guitar or piano, when the string is plucked (guitar) or struck (piano), it vibrates and produces a standing wave on the string. These vibrations are transmitted to the soundboard of the instrument, which amplifies the sound.
What is the process of locating objects by emitting sounds and interpreting the sound waves that are reflected back?
Explanation: Echolocation is the act of emitting sounds to the environment and listening to the echo of the emitted sound. Various animals use it like bats, shrew, swiftlets etc. The same concept is used in active sonar where it is used underwater to detect the depth and objects.
What is a system that uses the reflection of underwater sound waves to locate objects?
The study of sound. Created when specific pitches and sound qualities are used deliberately in a set pattern. Sonar. System that uses the reflection of underwater sound waves to detect objects.
When sounds are deliberately used in a set pattern what is created?
Chapter 11 – Sound
| A | B |
|---|---|
| music | made of sounds that are deliberately used in a regular pattern |
| sound quality | describes the differences among sounds of the same pitch and loudness |
| overtone | a vibration whose frequency is a multiple of the fundamental frequency |
What instrument makes a low sound?
The bass drum, like the double bass, is the biggest member of the percussion family and therefore makes the lowest sounds.
What are sounds above 20000 called?
Frequencies above 20,000 Hz are known as ultrasound.
How do vibrations affect the length of sound waves?
This amplifies the sound produced by the vibrating strings. Increasing the loudness of a sound changes the amplitude of the wave. The energy of a loud sound is also greater. The frequency, wavelength, and speed of the waves are not affected by the loudness.
What is the difference between radar and sonar?
Both are sensor systems which use the transmission and reception of return signals to function. Radar systems operate using radio waves primarily in air, while sonar systems operate using sound waves primarily in water (Minkoff, 1991).
How do sound waves travel through air?
The air is made up of many tiny particles. When sound is created, the air particles vibrate and collide with each other, causing the vibrations to pass between air particles. The vibrating particles pass the sound through to a person’s ear and vibrate the ear drum. Light travels much faster than sound through air.
