Question

the units of intensity of sound is​

Answer 1

Answer:

Sound intensity may be measured in units of energy or work—e.g., microjoules (10-6 joule) per second per square centimetre—or in units of power, as microwatts (10-6 watt) per square centimetre. Unlike loudness, sound intensity is objective and can be measured by auditory equipment independent of an observer's hearing.

Answer 2

The watt per square meter $(W/m2)$ is the unit of sound intensity. The usual definition is the measurement of sound energy as a quantity of noise sound intensity in the air at the listener position.

Explanation:

• The power carried by sound waves per unit area in a direction perpendicular to that region is described as sound intensity, also known as acoustic intensity.
• Sound pressure and sound intensity are not the same thing. Sound pressure, which is proportional to sound intensity, affects human hearing.
• The level discrepancies are referred to as "intensity" variances in consumer audio devices, although sound intensity is a specific quantity that cannot be measured with a simple microphone.
