Sound levels are measured in decibels. An increase of 10dB will sound twice as loud.

The average adult young man, who has not had his hearing compromised, will have a threshold of hearing of 0dB. Therefore, one-half of them will be able to hear sounds below 0dB; the other half will not.

The decibel unit was first used at Bell Laboratories, with regard to transmission losses on electrical circuits. Later this unit was used for Sound. It is named after Alexander G Bell of course; hence the capital B in dB.

What is the loudness of a sound?

Loudness of a sound can be measured by a sound pressure level meter. It belongs to psycho acoustics.Loudness is a subjective measure, which is often confused with objective measures of sound prtessure such as decibels or sound intensity. Filters such as A-weighting attempt to adjust sound measurements to correspond to loudness as perceived by the average human. However, as the perception of loudness varies from person to person it cannot be universally measured using any single metric. Loudness is also affected by parameters other than sound pressure, including frequency and duration. In acoustics volume is related to amplitude, sound pressure, and dynamics.There is subjectivly perceived loudness (volume), objectively measured sound pressure (voltage), and theoretically calculated sound intensity (acoustic power).Scroll down to related links and look at "All about loudness".


How loud a sound seems is determined by what measurement of the sound waves?

Loudness is determined by the amplitude of the sound waves.


What is the unit for measuring the relative intensity or loudness of sound?

Loudness N is measured in in sones.Loudness level LN is measured in in phons.Sound pressure level is measured in dBSPL, where the reference level of 0 dBSPL is the threshold of hearing.The ear drums and the microphones are only sensitve to the sound pressure.We measure the sound pressure with a sound level meter.Loudness is affected by sound pressure, frequency and its bandwidth, and duration (time).Usually sound is measured in Decibels.


How is sound measured?

Hertz for pitch (high or low) and decibels (dB) for volume (loudness).


What is the unit to measure the loudness of sound?

Loudness is the quality of a sound that is primarily a psychological correlate of physical strength or amplitude. You can try to measure the sound pressure in decibels. Scroll down to related links and look at "Loudness in sones - Wikipedia ", Loudness level in phon - Wikipedia ", and Subjectivly sensed loudness (volume), objectively measured sound pressure (voltage).

What is loudness and softness of sound measured in?

Loudness of sound is measured in decibels (dB) which quantifies the intensity or volume of a sound. Softness of sound is generally perceived subjectively and does not have a standardized unit of measurement, but is often described as quiet or faint.
