What is the intensity of sound at 122 dB?
Compare it to that of a whisper at 20 dB?
(both answers in W/m^2 units)
intensity level = 10*log(I/Io)
Io = threshold intensity = 10^-12 w/m^2
for intensity level = 122 dB
122 = 10*log(I1/10^-12)
I = 1.58 w/m^2
+++++++++
for intensity level = 20 dB
20 = 10*log(I2/10^-12)
I2 = 10^-10 w/m^2

What is the sound intensity level (in units of dB) when the intensity of sound is 5.05 mW/m2?
11. The sound level in decibels (dB) is given by dB-10log(101x), where x is the intensity of the sound given in W/cm2. a) Determine the sound level in dB for a sound having an intensity of 2 x 1012 W/cm b) What would be the sound level in dB if the sound intensity were doubled? 11. The sound level in decibels (dB) is given by dB-10log(101x), where x is the intensity of the sound given in W/cm2. a) Determine the...
1. If a sound of frequency 1000 Hz has intensity level 30 dB, what would be the intensity level of sound frequency 50 Hz which appears to have equal loudness? (Answer= 60 dB) 2. Intensity of 30 dB, 1000 Hz sound= (Answer= 1.000 x 10-9 W/m^2) *3. What is intensity (in W/m^2) of the equal loudness 50 Hz sound? (Answer is NOT 50.12 x 10^-12) *4. What is the ratio of the pressure variation (in amplitude) of the equal loudness...
Using a frequency-measuring lab device, I am to map out the sound intensity level distribution (dB) in a room (both with & without music playing) to create a 5x5 grid of 25 data points. Using the following data table of sound intensity level β(dB) and corresponding intensity I(W/m2), I also need to find the intensity to the nearest order of magnitude for the points on my sound intensity level maps. Here is the data table: Intensity levelβ(dB) Intensity I(W/m2) Example/effect...
A) What is the intensity (in W/m2) of a sound that has a level 3.00 dB lower than a 4.15 ✕ 10−9 W/m2 sound? B) what is the intensity in W/m2 of a sound that is 10.0 dB higher than a 4.15 x10-9 wW/m2 sound?
2) A referee whistle has a sound intensity level of 71.45 dB. Find the sound intensity in watts per square meter for the whistle. Compare this to a sound intensity level of 126.0 dB for a loud stadium. Would you be able to hear the whistle in the stadium?
What is the intensity (in W/m2) of a sound that has a level 3.00 dB lower than a 2.42 ✕ 10−9 W/m2 sound? W/m2 (b)What is the intensity (in W/m2) of a sound that is 10.0 dB higher than a 2.42 ✕ 10−9 W/m2 sound? W/m2
