How does the intensity of a 40-decibel sound compare to the intensity of a 20-decibel sound?
Given: Sound intensity level LI1 = 40 dB and sound intensity level LI2 = 20 dB.
Reference sound intensity Io = 10^−12 W/m² (Threshold of hearing)
Reference sound intensity level LIo = 0 dB-SIL (Threshold of hearing level)
Get sound intensity I1 when entering sound intensity level LI1 = 40 dB:
Sound intensity I1 = Io×10^(LI/10) W/m² = 10^−12×10^(40/10) = 0.00000001 W/m² = 10^−8 W/m².
Get sound intensity I2 when entering sound intensity level LI2 = 20 dB:
Sound intensity I2 = Io×10^(LI/10) W/m² = 10^−12×10^(20/10) = 0.0000000001 W/m² = 10^−10 W/m².
The sound intensity I1 = 10^−8 W/m² is 100 times more than the sound intensity I2 = 10^−10 W/m².
The sound intensity level LI1 = 40 dB is 20 dB more than the sound intensity level LI2 = 20 dB.

How does the wave from a loud sound compare to the wave of a soft sound?
A loud sound has a higher amplitude and a greater intensity, resulting in a larger wave with greater energy. In contrast, a soft sound has a smaller amplitude and lower intensity, producing a smaller wave with less energy.
What is sound mesured in?
Sound is measured in units called decibels (dB). Decibels quantify the intensity or loudness of sound and are used to compare different levels of sound from quiet to loud.
How does the use of a logarithmic scale affect the measurement of sound intensity in decibels?
The use of a logarithmic scale in measuring sound intensity in decibels allows for a wider range of values to be represented in a more manageable way. This scale compresses the range of sound levels into a more easily understandable format, making it easier to compare and analyze different levels of sound intensity.
What is the intensity of a sound wave called?
The intensity of a sound wave is called sound intensity. It measures the amount of energy transmitted by the sound wave per unit area. Sound intensity is measured in decibels (dB).
What does intensity of sound depend on?
The intensity of sound is dependent on the amplitude of the sound wave. The higher the amplitude, the greater the intensity of the sound. It is measured in decibels (dB) and corresponds to the loudness of the sound.
Compare and conyrast loudness and intensity?
Sound intensity or acoustic intensity can be calculated from the objective measurement of the sound pressure. The loudness is a psycho-acoustic subjective feeling, which is difficult to measure.
How does the intensity of a 40-decibel sound compare to the intensity 20-decibel sound?
100 times. Each bel (10 decibels) is ten times as loud thus 20 to 40 is 100 times.
Compare and Contrast the sound waves produced by someone whispering and someone shouting?
The difference is that someone whispering has a lower intensity and someone shouting has a higher intensity.

What is the name of sound intensity?
Sound intensity is mesured in decibels !
Intensity of a sound?
Sound intensity or acoustic intensity(I) is defined as the sound power Pacper unit area A. The usual context is the noise measurement of sound intensity in the air at a listener's location.
