How many times louder is a sound wave with an intensity of 50dB than a sound wave with an intensity of 20dB?
Better think of the sound pressure, when you are listening. Sound pressure moves your ears and the diaphragm of the microphones. The sound intensity is very small. The level of 50 dB is equal to 0.0000001 W/m2 acoustic intensity. Scroll down to related links and look at "Conversion of sound units (levels)".
What is louder 30dB or 21dB?
30dB is louder than 21dB. The decibel scale is logarithmic, so each increase of 10 dB represents a tenfold increase in sound intensity. Therefore, 30dB is 10 times louder than 20dB.
What is the intensity of a sound wave called?
The intensity of a sound wave is called sound intensity. It measures the amount of energy transmitted by the sound wave per unit area. Sound intensity is measured in decibels (dB).
What does intensity of sound depend on?
The intensity of sound is dependent on the amplitude of the sound wave. The higher the amplitude, the greater the intensity of the sound. It is measured in decibels (dB) and corresponds to the loudness of the sound.
Sound intensity decreases when what decreases?
Sound intensity decreases when the distance from the sound source increases. Sound intensity also decreases as the medium through which the sound is traveling becomes more dense or absorbs more of the sound energy.
How loud is 20db?
20db is a soft sound.

Is intensity a property of sound?
Sound intensity is a property of sound.

What is the name of sound intensity?
Sound intensity is mesured in decibels !
Intensity of a sound?
Sound intensity or acoustic intensity(I) is defined as the sound power Pacper unit area A. The usual context is the noise measurement of sound intensity in the air at a listener's location.
What is intensity of sound?
The sound intensity I or acoustic intensity is defined as the sound power per unit area. The usual context is the noise measurement of sound intensity in the air at a listener's location.
Sound intensity decreases when what decreases?
Sound intensity decreases when the distance from the sound source increases. Sound intensity also decreases as the medium through which the sound is traveling becomes more dense or absorbs more of the sound energy.
What is the meaning of intensity in sound?
The sound intensity I or acoustic intensity is defined as the sound power per unit area. The usual context is the noise measurement of sound intensity in the air at a listener's location.
What is the relationship between sound intensity and distance?
The relationship between sound intensity and distance is that sound intensity decreases as distance from the sound source increases. This is because sound waves spread out as they travel, causing the intensity of the sound to decrease with distance.
