In this model, loudness is a power function of sound intensity. When two tones are presented sequentially, each gives rise to a loudness value along the sensory continuum. In intensity-discrimination experiments, threshold is reached when the loudness difference between the tones exceeds a criterial...
In this paper I challenge the widely held assumption that loudness is the perceptual correlate of sound intensity. Drawing on psychological and neuroscientific evidence, I argue that loudness is best understood not as a representation of any feature of a sound wave, but rather as a reflection of...
In our former study of the loudness, noisiness and annoyance using actual and artificially synthesized sounds, it was found that there was little difference among loudness, noisiness and annoyance judgments with synthesized sounds. On the other hand, when actual recorded sounds were used, the ...
Intensity of a sound wave is defined as the amount of sound energy passing through a unit area per second. Loudness is a measure of the response of the ear to the sound. The loudness of a sound is defined by its amplitude. The amplitude of a sound decide
loudness level and intensity discrimination was investigated in the frequency range 0.5-6.5 kHz by comparing the intensity just-noticeable differences (jnd's) at a number of equal-loudness levels in the better and poorer ears of eight individuals with essentially unilateral hearing loss of cochlear ...
is not at the same time, the subjective feeling of the human ear is different, so each frequency has its own threshold sound pressure level and the pain threshold sound level, which can connect them to get the threshold line. There are thirteen loudness levels and units for the difference ...
We measure the loudness or intensity of sound in a unit called Decibel (dB). Decibel is a logarithmic scale, as we know that {eq}\begin{align} \bet...Become a member and unlock all Study Answers Start today. Try it now Create an ac...
These measurements are the basis of those numbers you see on the side of a lot of power tools. There are loads of places that you can get information about this - typically Sound Intensity Testing and Analysis: Siemens PLM Software - but you'll find that all of them use dB...
Vocal intensity is studied as a function of fundamental frequency and lung pressure. A combination of analytical and empirical models is used to predict so... IR Titze,J, Sundberg - 《Journal of the Acoustical Society of America》 被引量: 384发表: 1992年 Changes in phonation threshold pressure...
In regular programming the intensity of sound varies over a large range. However, sound levels in commercials tend to stay at or near peak levels. Other "tricks of the trade" are also used. Because low-frequency sounds can mask higher frequency sounds, advertisers filter out any noises that ...
