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.
Intensity of an earthquake can be measured on twelve point scale and magnituse causes magnet of the human's body
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.
Amplitude is the energy of a sound wave, which we also call Loudness
Yes, but it's not easy to understand. There is a dependance of sound levels and corresponding factors: Subjectivly sensed loudness (volume), objectively measured sound pressure (voltage), and theoretically calculated sound intensity (acoustic power). Scroll down to related links and look at "Sound level change and the loudness factor".
it is how loud the sound is ^Smartass comment. The real answer: Loudness is determined by the intensity of sound waves.
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.
the Decibel it measures the loudness and intensity
Yes the loudness of a sound is called its intensity.
By its amplitude. Really loudness is sound intensity & intensity depends on square of amplitude ie. higher the amplitude higher the intensity which means higher the loudness.
Loudness is the colloquial term and intensity is the scientific term. More the intensity higher the loudness. Same way in case of light, higher the intensity of radiation, we call colloquially that as more brightness.
