Order to reduce the loudness of a sound, we have to
$(a)$. decrease its frequency of vibration of the sound
$(b)$. increase its frequency of vibration of the sound
$(c)$. decrease its amplitude of vibration of the sound
$(d)$. increase its amplitude of vibration of the sound

Academic Physics NCERT Class 8

The loudness of a sound gets increased by increasing its amplitude and gets decreases by decreasing its amplitude.

So, option $(c)$ is correct.

The loudness of sound is determined by its$(a)$. amplitude of vibration$(b)$. ratio of amplitude and frequency of vibration$(c)$. frequency of vibration$(d)$. product of amplitude and frequency of vibration
Sound Vibration Propagation of Sound
The loudness of sound depends on$(a)$. its amplitude$(b)$. its time period$(c)$. its frequency$(d)$. its speed
Pitch of sound is determined by its$(a)$. frequency $(b)$. speed$(c)$. amplitude $(d)$. loudness
When we change a feeble sound to a loud sound, we increase its:(a) frequency (b) amplitude (c) velocity (d) wavelength
What happens to the loudness of a sound if its amplitude decreases?
Sound Produced Vibration Object
Fill in the blanks with suitable words.$(a)$. Time taken by an object to complete one oscillation is called______.$(b)$. Loudness is determined by the ________ of vibration.$(c)$. The unit of frequency is _________.$(d)$. Unwanted sound is called _________.$(e)$. The shrillness of a sound is determined by the _________ of vibration.
Fill in the blanks : The Greater the amplitude of the vibration, the _____ is the distance a sound will travel before dying out
What happens to the pitch of a sound if its frequency increases?
Define amplitude, time period, and frequency of sound wave.
(a) What is meant by the ‘loudness’ of sound? On what factor does the loudness of a sound depend?(b) Draw labelled diagrams to represent (a) soft sound, and (b) loud sound, of the same frequency.
Name the characteristic of sound which depends on (a) amplitude (b) frequency, and (c) waveform.
Before playing the orchestra in a musical concert, a sitarist tries to adjust the tension and pluck the string suitably. By doing so, he is adjusting$(a)$. intensity of sound only$(b)$. amplitude of sound only$(c)$. frequency of the sitar string with the frequency of other musical instruments$(d)$. loudness of sound
