What does the loudness of sound depend upon?
The amplitude of the wave determines the loudness of a sound wave. A larger amplitude means a loud sound while a smaller amplitude means a soft sound. If the amplitude is high then the sound will be louder and the sound will be feeble if the amplitude is low. Loudness is proportional to the square of the amplitude.
How does the loudness of sound depend upon the amplitude?
Answer. Loudness of sound is directly proportional to the square of the amplitude of vibration producing the sound.
Does loudness of sound depend on intensity?
Loudness depends on the intensity of the sound and not on the type of instrument used. The greater the force with which the instrument is struck, the greater is the amplitude of the wave which means greater is the intensity and loudness.
How does loudness of sound depend upon amplitude class 8?
Loudness is proportional to the square of the amplitude. Thus, if the amplitude is increased by three times, the loudness increases by nine times.
What is loudness of sound What factors does it depend on class 9?
Answer: Loudness of a sound depends on the amplitude of the vibration producing that sound. Greater is the amplitude of vibration, louder is the sound produced by it. The amplitude of the sound depends upon the force with which an object is made to vibrate.
In what way does loudness of sound depends on amplitude class 8?
Answer: Loudness of sound is proportional to the square of amplitude. If the amplitude is tripled, the loudness increases by nine times.
How do loudness and pitch of sound depends on amplitude and frequency respectively?
Answer. Higher the amplitude of sounder, louder the sound is and higher the frequency of sound waves, higher the pitch of the sound will be.
Which of the following determines the loudness of a sound wave?
amplitude of vibration
The intensity or loudness of a sound depends upon the extent to which the sounding body vibrates, i.e., the amplitude of vibration. A sound is louder as the amplitude of vibration is greater, and the intensity decreases as the distance from the source increases. Loudness is measured in units called decibels.
What is loudness of sound in physics?
The loudness of a sound relates the intensity of any given sound to the intensity at the threshold of hearing. It is measured in decibels (dB). The threshold of human hearing has an intensity of about . 0000000000001 watts per meter squared and corresponds to 0 decibels.
On which factors loudness of sound depends Class 8?
Solution: The loudness of a sound depends on the amplitude of vibration producing the sound.
What are the factors on which loudness of sound depends Class 8?
The loudness of a sound depends on the amplitude of the wave. The loudness of sound is proportional to the square of the amplitude. The loudness of sound also depends on the sensitivity of the human ear.
On what factor does the loudness and pitch of sound depends explain?
Answer. The pitch of a sound depends on the frequency while loudness of a sound depends on the amplitude of sound waves.
