What is the definition of intensity as related to physics?
Intensity = Power / Cross sectional area
What does sound depend on?
Sound Intensity = Power / Area. So the more power delivered to a smaller area the greater the intensity.
What is Distinguish between intensity and loudness?
the Decibel it measures the loudness and intensity
What are variations in sound intensity?
The loudness has to do with the sound field quantity called sound pressure or sound pressure level (SPL). The sound intensity or acoustic intensity means the sound energy quantity. Our ears and the microphone diaphragms are moved by the sound pressure variations.
How do the amplitudes of a decibel sound and a 100-decibel sound compare?
The power or intensity of the louder one is 10 billion times the power or intensity of the softer one. Since the power or intensity is typically proportional to the square of the wave amplitude, the amplitude of the louder one is a mere 100,000 times the amplitude of the softer one.
