The "loudness" of a sound is subjective, that is, it varies by the perception of the individual and cannot be measured. What is 'loud' to one person may not be to another, but increasing the amplitude will make it 'louder' to both of them.

You can measure the amplitude or sound pressure in decibels with a sound pressure level meter. Microphones and eardrums are only sensitive to the sound pressure. Forget the sound 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 really a subjective measure and is often confused with objective measures in decibel units of sound pressure or sound intensity.


The amplitude of the sound wave determines the loudness (intensity).


Amplitude decides the intensity (loudness) of the sound. Intensity is directly proportional to the square of the amplitude of vibration.


No- amplitude is the height of the wave..loudness is related to amplitude, but they are not the same


The higher the amplitude the greater is the psychoacoustic feeling of the loudness.


Loudness and pitch means amplitude and frequency.


Loudness is the quality of a sound that is the primary psychological correlate of the amplitude of sound (physical strength). It is a feeling, which is neither the sound pressure as field quantity nor the acoustic intensity as energy quantity. Scroll down to related links and look at "Loudness - Wikipedia".


The amplitude is related to the loudness of the sound.


Amplitude is related to the intensity because square of the amplitude is proportional to the intensity of the wave.


The amplitude of a sound wave is the measure of the intensity of the sound, such as loudness.


No, pitch is related to wave frequency, loudness is related to wave amplitude.


The square of the amplitude gives the intensity of the wave. Intensity in case of sound is sensed as loudness and in case of light as brightness.


Amplitude is intensity. It refers to the strength of a sound wave, which the human ear interprets as volume or loudness and if you decrease the amplitude you also decrease its intensity.


(amplitude)2 is directly proportional to loudness.


In terms of the physics of sound, pressure or intensity is controlled by the amplitude of a sound wave. Amplitude is a dominant factor in loudness, but other factors are at play.Loudness is a quality of the perception of sound. It is the psychological corollary of physical intensity or amplitude. Loudness is a subjective measure that is often confused with objective measures of sound pressure or sound intensity.The perception of loudness varies from person to person, therefore it cannot be universally measured using any single metric. Loudness is also affected by parameters other than sound pressure, including frequency and duration.Scroll down to related links for more comprehensive information.


As we increase the amplitude then intensity of sound increases. The physical term is intensity. Practically we mean it as loudness. More amplitude then loud sound. If amplitude is less then sound is so soft.


Loudness means amplitude and pitch means frequency.


Intensity of sound is related to soft and loud sound. Intensity is directly proportional to the square of the amplitude.


The loudness of a sound (or intensity) corresponds to the sound wave's amplitude. The amplitude of a wave is the distance from the midpoint of the wave to a high-point (crest) or low-point (trough).


loudness, number of decibels, magnitude, amplitude, intensity, pitch



loudness is to amplitude as pitch is to frequency


Amplitude is the part of a wave that the loudness of a sound depends on.


Loudness is the quality of a sound that is the primary psychological correlate of physical strength (amplitude). It is a feeling, which is neither the sound pressure as field quantity nor the acoustic intensity as energy quantity. Scroll down to related links and look at "Loudness - Wikipedia".
