Answer 2

Sound intensity level is measured by (B) decibel.

Explanation:

• The power is carried by the wave of sound per unit area in a direction that is perpendicular to the area. This intensity is measured by decibel.
• Vibration that propagates through a transmission medium such as gas, liquid, or solid.
• However, hertz is used to refer to the frequency of the sound wave to the number of cycles. the vibration per second is called one hertz.
• second is the unit that is used in the measuring of time which makes the minute.
• $KG$ is the $SI$ unit that is used to measure the mass of an object.
