The intensity of sound at 121 dB is approximately 10^9 W/m^2. Sound intensity is measured using the formula I = 10^(dB/10), where dB is the decibel level.

What sound intensity corresponds to 92 dB?

A sound intensity of 10^-9 W/m^2 corresponds to a sound level of 92 dB. Sound intensity is measured on a logarithmic scale in decibels (dB), with each increase of 10 dB representing a 10-fold increase in intensity.


How much louder is a sound wave that has an intensity of 50 dB than a sound wave with an intensity of 20 dB?

The power in the wave is [ 30 dB = 1,000 times ] greater.


How much more is a dB sound than a dB sound?

A 10 dB increase represents a sound that is 10 times greater in intensity compared to a 1 dB sound. Each 10 dB increase corresponds to a tenfold increase in sound intensity.


What is the unit of sound intensity measurement?

The unit of sound intensity measurement is the decibel (dB).


What is sound intensity measured in?

Reference sound intensity Io = 10^−12 W/m² (Threshold of human hearing). Reference sound intensity level LIo = 0 dB-SIL (Threshold of human hearing intensity level). The sound intensity I is measured in watts per meter squared. The sound intensity LI level is measured in decibels (dB).


How many time more is the orchestra than the soloist if the orchestra has a sound intensity of 90 db and the soloist has a sound intensity of 70 db?

The difference in sound intensity between the orchestra and the soloist is 20 dB. Since the decibel scale is logarithmic, a 10 dB increase represents a doubling of sound intensity. Therefore, the orchestra is 100 times louder than the soloist.


How do you measure to intensity of sound?

Sound intensity is measured in decibels (dB) with a sound level meter. The meter detects and quantifies the pressure variations in sound waves. The higher the dB value, the louder the sound.


What is the intensity of 20db sound?

The intensity of a 20 dB sound is approximately 10^-8 watts per square meter. Sound intensity is measured on a logarithmic scale, where each 10 dB increase represents a tenfold increase in intensity.


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.


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.


How much does dB?

dB (decibels) is a unit used to measure the intensity of sound. It is a logarithmic scale that compares the intensity of a sound to a reference level, usually the threshold of hearing for the average human ear. The higher the dB value, the louder the sound.


An increase of 20 dB increases the sound intensity by a factor of?

A factor of 100. Every 10 dB, the intensity increases by a factor of 10.A factor of 100. Every 10 dB, the intensity increases by a factor of 10.A factor of 100. Every 10 dB, the intensity increases by a factor of 10.A factor of 100. Every 10 dB, the intensity increases by a factor of 10.
