Sound is basically a vibration that touches your ear and makes your ear vibrate so you can hear the sound. Something like a musical instrument or someone tapping their knees makes the air around the object vibrate and the air around the object that is now vibrating keeps going until it runs out of energy, if someone's ear where in the way of the vibration it would vibrate the persons ear so that the person could hear the sound. Sound is measured in frequency the quicker the frequency the higher the note or noise.
Sound can be measured in many ways such as decibels (unit of sound) there is a special machine which you can by that measures how many decibels something makes. A pin makes 10 decibels where as a loud persons personal stereo can make up to 80 decibel's. Frequency is also a good way of measuring sound because even without hearing the sound you can know whether or not it is a high or low note. If the frequency is very fast then there is a high note but if the frequency is very slow then there is a low note.

∙ 13y agoSound and noise is usually measured with a Sound Pressure Level Meter (SPL meter) in decibel or the sound pressure in pascals or N/m² - and not the sound intensity in W/m².

In which the loudness of sound is measured?
Sound is measured in decibels
What is most often used to measure the intensity of a sound?
The intensity of sound is most often measured by the Decibel meter. It can also be called the sound level meter or the dB Meter. It is used to accurately and objectively measure the sound or noise that one can hear.
What is the definition of intensity in terms of sound?
Sound intensity or acoustic intensity (I) is defined as the sound power (Pac) per unit area (A). The usual context is the noise measurement of sound intensity in the air at a listener's location as a sound energy quantity (measured in W/m²). Our eardrums and microphone diaphragms are moved by sound pressure deviations (p), which is a sound field quantity (measured in pascals Pa). So we measure the sound with a SPL meter (Sound Pressure Level) in decibels.
What causes intensity of sound?

So we measure the sound with a SPL meter (Sound Pressure Level) in decibels.
Sound is measured in what types of unit?
Sound is measured in decibels, which are commonly shortened to "dBs".
How is noise measured?
Noise levels of sound in the air are measured by a sound pressure level meter (SPL meter).Noise levels in an electronic circuit are measured by a volt meter.
How is sound level measured. At what level does sound become noise?
Sound level is measured in decibels (dB) using a sound level meter. Sound becomes noise when it is unwanted or excessive, typically around 85 dB for prolonged exposure or 120 dB for instant damage. Noise can also be subjective, as what is considered noise can vary from person to person.
Is sound produced by changes in force's pressure's and velocity?
Sound and noise are sound pressure variations measured by an SPL meter. SPL = Sound Pressure Level.
How do you measure the noise of a fan?
The noise of a fan can be measured in decibels using a sound pressure level meter. Knowing the level of noise allows people to classify as pollution or conducive.
Systolic is measured at which korotkoff?
The systolic pressure is measured at the first Karotkoff sound (stage I), it is the first tapping noise that you hear with a stethoscope when taking a manual blood pressure.
What noise is measured in?
Decibels
In which the loudness of sound is measured?
Sound is measured in decibels
What is the duration of Sound of Noise?
The duration of Sound of Noise is 1.7 hours.
What is the opposite of a sound?
Silence is the opposite or antonym of sound.
What is most often used to measure the intensity of a sound?
The intensity of sound is most often measured by the Decibel meter. It can also be called the sound level meter or the dB Meter. It is used to accurately and objectively measure the sound or noise that one can hear.
When was Sound of Noise created?
Sound of Noise was created on 2010-05-18.
When was Sound of White Noise created?
Sound of White Noise was created in 1993.
