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 meaning of SOUND-INTENSITY LEVEL is the relative sound intensity at any point in a sound field as compared with a specified standard intensity that is usually expressed in decibels above or below the standard.
1. the amount of energy transmitted (as by acoustic or electromagnetic radiation); "he adjusted the intensity of the sound" "they measured the station's signal strength" 2. high level or degree; the property of being intense 3. the magnitude of sound (usually in a specified direction); ...
2. Physics The amount or degree of strength of electricity, light, heat, or sound per unit area or volume. 3. a. The strength of a color, especially the degree to which it lacks its complementary color. b. See saturation. American Heritage® Dictionary of the English Language, Fifth ...
5.1.2 Sound power and sound intensity Any sound source radiates power in the form of sound transmission. When the sound power W passes through an area A, the sound intensity I is defined as power per unit area: (5.3)I=WA The sound intensity can be related to sound pressure: (5.4)I=...
meaning. Indeed, a body of research suggests that high-intensity emotion expressions are better ‘recognized’1,2,3,4,5. Importantly, both discrete-emotion and dimensional theories predict this pattern of results, although by different mechanisms: either maximized distance to other emotions by the ...
The meaning of the proposed transition is that the field intensity distribution in the specified phase space is less sensitive to sound velocity fluctuations than in the original 2D depth-time space. This fact can be used in solving inverse problems. As an example, we consider the reconstruction...
May it not be maintained that, without knowing these theories, we have a vague surmise of them, that behind the more intense sound we guess the presence of ampler vibrations which are propagated in the disturbed medium, and that it is with a reference to this mathematical relation, precise ...
RMS values are commonly used for physical quantities that oscillate and have an average of zero, like pressure in a sound wave. RMS acoustic pressure normalized to its maximum is not a measure of absolute cry intensity, but rather a measure of constancy of emission; it measures the fraction ...
Only a pure tone of 1 kHz measured in phons is equivalent to a dB-SPL value. Distinguish carefully when looking at the volume (magnitude of sound). Sone is part of the loudness. Phon is part of the loudness level. Try to avoid the laymen's word "intensity". dB or dB-SPL is the ...
