The meaning of SOUND INTENSITY is the intensity of a sound in a specified direction measured by the average rate at which sound energy passes through a unit area normal to that direction and commonly expressed in ergs per second per square centimeter.
Sound Intensity (I)doi:10.1007/978-3-540-29678-2_5522The average rate of sound energy transmitted in the specified direction through a unit area normal to this direction at the point considered. For cases in air, I p2=_0c , where p is pressure, ρo is......
The unit of SL is called the decibel (abbreviated dB). I is the intensity of the sound expressed in watts per meter and I o is the reference intensity defined to be 10-12 W/m2. This value of I o is the threshold (minimum sound intensity) of hearing at 1 kHz for a young person ...
We found that CAP responses exhibit transients at each switch in noise intensity: decreases in intensity produce negative transients while increases in intensity produce positive transients (Fig.1c). After a few milliseconds, the responses settle to a steady state that is relatively independent of s...
14. (intr) to resonate with a certain quality or intensity: to sound loud. 15. (copula) to give the impression of being as specified when read, heard, etc: to sound reasonable. 16. (tr) to pronounce distinctly or audibly: to sound one's consonants. 17. (Law) law (usually foll...
will form sound shadow zones, which would be “lighten” only by the sound reflections from the sea surface and bottom, where the sound intensity is thus weak enough. Whenever a receiver departs from the sound source to far distances along z = z1, the received sound intensity will pass ...
absorption coefficient- a measure of the rate of decrease in the intensity of electromagnetic radiation (as light) as it passes through a given substance; the fraction of incident radiant energy absorbed per unit mass or thickness of an absorber; "absorptance equals 1 minus transmittance" ...
A fundamental feature of this type of logarithmic scale is that each unit of increase in the decibel scale corresponds to an increase in absolute intensity by a constant multiplicative factor. Thus, an increase in absolute intensity from 10-12to 10-11watt per square metre corresponds to an incr...
In addition to traditional sound pressure methods, sound power can also be measured using the sound intensity method, offering distinct advantages in various applications. Sound intensity measures both the magnitude and direction of acoustic energy flow, allowing for a more flexible and accurate assessme...
