Question

What's do you mean by intensity of sound?

Answer 1

1. Intensity is the quantity of energy the wave conveys per unit time across a surface of a unit area, and it is also equivalent to the energy density multiplied by the wave speed.
2. Intensity is expressed as:
   $\mathrm{intensity}=\frac{\mathrm{power}}{\mathrm{area}}$
3. The mathematical expression for sound intensity:
   $\mathrm{sound}\mathrm{intensity}=10{\log }_{10}\frac{\mathrm{sound}\mathrm{intensity}}{\mathrm{initial}\mathrm{sound}\mathrm{intensity}}$
4. The power of sound per unit area is used to define sound intensity.
5. The measurement of sound intensity in the air is the typical context.
6. The surface of the sound source also plays a role.
7. The kinetic energy of the mass of air is produced by the source's and the vibrating surface's increasing amplitudes.
8. The mass of the air that is vibrating and its average speed both increase this kinetic energy.
9. The distance from the sound source affects how strongly the ear perceives a sound.
10. The characteristics of the elastic medium between a sound source and the ear also affect intensity.
11. The sound intensity is diminished by non-elastic materials.
