The loudness cannot be measured, because it is a personal psycho acoustic perception, and differs with each listener.

The sound pressure level, a physical phenomena, can be measured by a SPL meter.

Does the amplitude determine the loudness of a sound?

No, the amplitude of a sound wave determines its intensity, not its perceived loudness. Loudness is subjective and depends on the sensitivity of the human ear to different frequencies at different sound pressure levels.

Why the water levels in the various Manometer tubes are different?

The water levels in different manometer tubes are different because they reflect the pressure differences between two points in a system. The height difference in the tubes indicates the pressure differential between the two points they are measuring. This pressure difference causes the fluid to rise or fall in each tube to balance the pressures.

What is the difference between a pressure cooker with a 15 bar and a pressure cooker with a 20 bar rating?

The main difference between a pressure cooker with a 15 bar and a pressure cooker with a 20 bar rating is the maximum pressure they can reach. A 20 bar pressure cooker can reach higher pressure levels than a 15 bar pressure cooker, which can affect cooking times and the tenderness of food.


What determines loudness of the sound?

Loudness is a word from psychoacoustics. It is the quality of a sound that is the primary psychological correlate of physical strength or amplitude. Loudness is a really subjective measure. It 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 and look at "Dependance of sound levels and the corresponding factors - The subjectivly sensed loudness (volume)".


Loudness or sound levels measured in units called?

decibels


What are the differences between a Wacom Intuos and a Wacom Bamboo tablet?

The significant difference between the two models lies in the pressure sensitivity of each tablet. The Intuos model is much more sensitive--it has some 2000 levels of pressure sensitivity, versus the around 1000 levels of sensitivity in the Bamboo Fun. :)


What is the difference between A-Levels and AS-Levels?

AS levels are the first half of A levels, if you stop after the first year you get an AS qualification.


What measures the loundness of sound?

You cannot "measure" the subjective loudness feeling in decibel with a "dB"-meter. You can measure the objective sound pressure with a "sound pressure meter" that shows the sound pressure in pascals or the sound pressure level SPL in dB or dBA.


How will you measure loudness in 3 ways?

Using a decibel meter: A decibel meter measures sound levels in decibels (dB). Using a sound level meter: A sound level meter provides a reading of sound pressure levels in decibels. Subjective rating: Loudness can also be evaluated subjectively based on human perception, ranging from "quiet" to "very loud".


What is a unit used to express loudness of a sound?

The psychoacoustic loudness N is measured in sones. The loudness level (Volume) LN is measured in phons. Scroll down to related links and look at "Conversion of sone to phon and the problem with dBA".
