Factors affecting the loudness or intensity of sound:
The loudness or intensity of sound is determined by various factors. Let's discuss each of these factors in detail:
1. Amplitude of a sound wave:
The amplitude of a sound wave refers to the maximum displacement of particles in a medium from their equilibrium position. It determines the loudness or intensity of sound. The higher the amplitude of a sound wave, the louder the sound will be. When the amplitude increases, the air particles are displaced to a greater extent, creating a more intense sound. Conversely, a lower amplitude results in a softer sound.
2. Area of a vibrating body:
The area of a vibrating body does not directly influence the loudness or intensity of sound. Therefore, option 'B' is incorrect.
3. Distance from the source of sound:
The distance from the source of sound also affects the loudness or intensity of sound. As sound waves travel through a medium, they spread out in all directions. This causes the sound energy to be distributed over a larger area, resulting in a decrease in loudness or intensity with increasing distance. Therefore, the closer we are to the source of sound, the louder it will be, and as we move farther away, the sound becomes softer.
Summary:
In summary, the loudness or intensity of sound primarily depends on the amplitude of a sound wave. The amplitude determines the displacement of air particles and hence the intensity of the sound. The area of a vibrating body does not influence the loudness of sound, and the distance from the source of sound affects the loudness by causing the sound energy to spread out over a larger area.
