Sound intensity, also known as acoustic intensity, is defined as the power carried by sound waves per unit area in a direction perpendicular to that area. The SI unit of intensity, which includes sound intensity, is the watt per square meter (W/m2). One application is the noise measurement of sound intensity in the air at a listener's location as a sound energy quantity.Sound intensity is not the same physical quantity as sound pressure. Human hearing is sensitive to sound pressure which is related to sound intensity. In consumer audio electronics, the level differences are called "intensity" differences, but sound intensity is a specifically defined quantity and cannot be sensed by a simple microphone.
Sound intensity level is a logarithmic expression of sound intensity relative to a reference intensity.
Hello guys!
I just need a tip. I wish to derive the intensity for a three-slit grating, and got stuck pretty close to the right answer. I've got a snapshot of my work at www.mypost.kit.net
THANKS!
I have no idea what I'm doing wrong on this one. I'm having problems somewhere in the log conversions to W/m^2 I believe.
A siren mounted on the top of towers produces a noise of 120 dB at a distance of 2 meters. Treating the siren as a point particle (and ignoreing reflection and...
Hi, i was interested in a detector that could measure the intensity of a radio wave of a particular frequency, at a point. Either by using a capacitor or a radio diode (or any other way). If such a devise exists please tell me where I can find one, if not any advise on how I might be able to...
The upper limit of the intensity level of sound waves is about 194 dB. This intensity corresponds to 100% modulation of the air; that is, the amplitude of the pressure oscillations corresponds to that of atmospheric pressure. What intensity (W/m^2) would be required to generate this level of...
If 2 flutist play their instruments together at the same intensity, is the sound twice as loud as that either flutist playing alone at that intensity? Why or why not?
I have a few pretty simple questions that I can't seem to find a clear answer to on the net...
The energy of a light wave is directly proportionate to frequency and inversely proportionate to wavelength.
This is due to the energy of a Photon being equal to hf.
"f" is a constant, so the...

A microphone in the ocean is sensitive to sounds emitted by popoises. To produce a usable signal , sound waves striking the microphone must have an intesity of 10.6 dB. If porpoises emit sound waves with a power of 0.0502 W, how far can a porpoise be from the microphone and...
having problems trying to understand and derive the equation for intensity in the double-slit interference pattern. any sort of help would be welcomed. thanks

X and Z represent point charges of -2.4 x 10^-3 C and +3.3 x 10^-2 C respectively. Calculate the magnitude and direction of the electric field intensity at point Y, 5.00 cm from X and 8.50 cm from Z (they all live in a line).
Can sumone help me?
How would you calculate the intensity using relative amplitude.
Say for a violin...how would you calculate it's intensity for one of it's harmonics or overtones.
Hello Forum members
I need help on a homework problem that I am unable to solve. the problem is as follows
Given the radius of a star of 9.0 * 10^3 m and surface temperature of
10000 k (blackbody)find the intensity of radiation (watts/m^2) incident on a planet that is located 2.4 * 10^11...
A Radioactive source produces an intensity of radiation of 6000 Bq/M^2 at a distance of 5 meters from a source. Determine the intensity of the radiation at a distance of
a)10 metres
* Well i think it will be 3000 Bq/m^2 since it is further distance and is halved, can someone verify?
b)...
