Question

Large amplitudes of sound vibrations will produce ____
A) Loud sound
B) Soft sound
C) Shrill sound
D) Feeble sound

Answer 1

Hint: A sound's source vibrates, colliding with nearby air molecules, which collide with their neighbors, and so on. This causes a wave of vibrations to travel through the air to the eardrum, which then vibrates as well.

Complete answer:
In physics, the sound is a vibration that travels through a transmission medium such as a gas, liquid, or solid as an acoustic wave. Sound is the reception of such waves and the brain's perception of them in human physiology and psychology. Only acoustic waves with frequencies in the audio frequency range (roughly 20 Hz to 20 kHz) elicit an auditory perception in humans.
These are sound waves with wavelengths ranging from 17 meters (56 feet) to 1.7 centimeters in the air at atmospheric pressure (0.67 in). Ultrasound is defined as sound waves with a frequency greater than 20 kHz that are inaudible to humans. Infrasound is defined as sound waves with a frequency below 20 Hz. The hearing ranges of different animal species differ.
The amount of energy carried by a wave is proportional to its amplitude. A large amount of energy is carried by a high amplitude wave, while a small amount of energy is carried by a low amplitude wave. The intensity of a wave is defined as the average amount of energy passing through a unit area per unit of time in a specific direction.
The intensity of the sound increases as the amplitude of the sound wave increases. Higher-intensity sounds are perceived to be louder. Decibels are commonly used to express relative sound intensities (dB). The square of the amplitude of the vibration producing the sound determines the loudness of the sound.
Thus, a Large amplitude of sound vibrations will produce a loud sound. So, option (A) is correct.

Note:
The area covered by sound waves grows as the distance between the sound source and the listener grows. Because the same amount of energy is dispersed over a larger area, the sound's intensity and volume are reduced. This explains why, as you get closer to the source, even loud sounds fade away.
