What loudness and intensity are not the same concept due to the interaction of?
Sound intensity or acoustic intensity can be calculated from the objective measurement of the sound pressure. The loudness is a psycho-acoustic subjective feeling, which is difficult to measure.
The amplitude of a sound wave determines its?
The loudness has to do with the sound field quantity called sound pressure or sound pressure level (SPL). The sound intensity or acoustic intensity means the sound energy quantity. Our ears and the microphone diaphragms are moved by the sound pressure variations.
How is intensity related to loudness?
Assuming we are talking about sound, intensity measures the power in a sound wave. Mathematically, it is the product of the sound pressure and the particle velocity, and is measured in watts per square meter. Loudness usually refers to the (subjective) perception of sound intensity by people. It is related to intensity, but also depends upon frequency. The human ear perceives increases in sound intensity roughly on a logarithmic scale, so for example the sound intensity needs to increase by about a factor of ten to create the perception that the sound is twice as loud. This is the motivation for the decibel system, which measures sound intensity on a logarithmic scale.
If you double the distance from a source by what factor will the decibel level increase?
Sound level dependence and the respective factors of subjective volume (loudness), objective sound pressure (voltage), and acoustic power (sound intensity). It is not easy to understand the relationship between these terms: There is the subjective and artificial perceived concept of loudness, the measurable voltage at a microphone which is proportional to the sound pressure and there is the calculated sound intensity or acoustic power. How many decibels (dB) is twice (double, half) or three times as loud? Loudness/Volume - What is the dependence of the level in decibels? Scroll down to related links and look at "Sound level dependence and the respective factors" and when you think of "sound pressure" look at "Sound pressure p and the inverse distance law 1/r".
The loudness of a sound is related to what?
Loudness is the quality of a sound that is the primary psychological correlate of physical strength or amplitude. Loudness is a subjective felt impression and is in some way related to the objective measure of sound pressure.
Compare and conyrast loudness and intensity?
Sound intensity or acoustic intensity can be calculated from the objective measurement of the sound pressure. The loudness is a psycho-acoustic subjective feeling, which is difficult to measure.
When intensity increases does the loudness stay the same?
No. Sound intensity or acoustic intensity can be calculated from the objective measurement of the sound pressure. The loudness is a psycho-acoustic subjective feeling, which is difficult to measure.
What loudness and intensity are not the same concept due to the interaction of?
Sound intensity or acoustic intensity can be calculated from the objective measurement of the sound pressure. The loudness is a psycho-acoustic subjective feeling, which is difficult to measure.
How is the loudness of a sound related to the amplitude?
Loudness is really a subjective measure and is often confused with objective measures in decibel units of sound pressure or sound intensity.
Is sound intensity subjective or is loudness subjective Why?
Sound intensity is objective, because it's just a measure of the sound power per unit area. Loudness is subjective, because it has to take into account the sensitivity of the ear and its different responses to different frequencies in the sound. A sound with a frequency of 45 kHz would have no "loudness", since our ears don't respond to that frequency at all. But it would still have intensity, because the sound is still carrying energy.
How are intensity magnitude and loudness related to each other?
Loudness of sound means the physical strength or amplitude. It is a subjective measure, which is very often confused with objective measures of sound pressure or sound pressure level. The SPL meter is a good helper.
How does sound intensity differ from loudness?
Sound intensity or acoustic intensity can be calculated from the objective measurement of the sound pressure. The loudness is a psycho-acoustic subjective feeling, which is difficult to measure.
What is the difference between loudness and intensity?
Sound intensity or acoustic intensity can be calculated from the objective measurement of the sound pressure. The loudness is a psycho-acoustic subjective feeling, which is difficult to measure.
What is the relationship between intensity and the loudness of sound?
Sound intensity or acoustic intensity can be calculated from the objective measurement of the sound pressure. The loudness is a psycho-acoustic subjective feeling, which is difficult to measure.

Loudness and intensity compares and contrasts?
Loudness is the quality of a sound that is the primary psychological correlate of physical strength or amplitude. Loudness is a subjective felt impression and is in some way related to the objective measure of the sound pressure. Neither our ear drums nor the microphone diaphragms can convert acoustic intensity. Therefore only use the sound pressure for measuring. To measure the loudness feeling is a difficult thing.
