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.
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 ...
Sound with intensity greater than 85 decibels can cause ear damage, and sound with intensity above 120 decibels causes pain. sound 2 1. A long body of water, wider than a strait, that connects larger bodies of water. 2. A long, wide inlet of the ocean, often parallel to the coast. ...
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" ...

To faithfully encode complex stimuli, sensory neurons should correct, via adaptation, for stimulus properties that corrupt pattern recognition. Here we investigate sound intensity adaptation in the Drosophila auditory system, which is largely devoted to
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 ...

The sound intensity level was selected as the average between the sound intensity obtained when a fish would start to detect the 100 Hz tone (GCamp6s fluorescent activity seen in the ON), and the sound intensity obtained when a fish would start to have escape responses to 100 Hz tones...
