How is intensity related to loudness?
Assuming we are talking about sound, intensity measures the power in a sound wave. Mathematically, it is the product of the sound pressure and the particle velocity, and is measured in watts per square meter. Loudness usually refers to the (subjective) perception of sound intensity by people. It is related to intensity, but also depends upon frequency. The human ear perceives increases in sound intensity roughly on a logarithmic scale, so for example the sound intensity needs to increase by about a factor of ten to create the perception that the sound is twice as loud. This is the motivation for the decibel system, which measures sound intensity on a logarithmic scale.
How many times louder is an 80 dB sound compared to a 40 dB sound?
1000 times louder. Every 10 decibel, the intensity increases by a factor of 10.1000 times louder. Every 10 decibel, the intensity increases by a factor of 10.1000 times louder. Every 10 decibel, the intensity increases by a factor of 10.1000 times louder. Every 10 decibel, the intensity increases by a factor of 10.
By what factor will the noise intensity change when sound levels increases by 8 db?
That answer is not easy, but ccroll down to related links and look at "Sound level dependence and the corresponding factors". ten
When a sound intensity increases by factor of 10 it's decibel reading increases by blank?

Which wave property decreases as you get farther away from the source of a sound?
Intensity
How does the intensity of a sound wave change if the distance from the source increases by a factor of 2?
The intensity increases by a factor of 4-APEX
If the energy carried by a sound wave is multiplied by a thousand times bywhat factor does the intensity of the sound wave increase?
The factor does the intensity of the sound waves increase because the intensity of sound waves is related to the amplitude. Sound with a greater amplitude also has a greater intensity.
What factor will increase the speed of a sound wave in the air?
Speed of sound would increase as the temperature of the air increases Speed of sound increases as humidity of air increases Speed of sound is affected by the density of the air. As density increases velocity of sound decreases

How are decibels doubled and measured?
That is a missunderstanding. Decibels are never doubled. The ratio or the factor can be doubled.Doubling means the "factor 2". What does doubling of a "sound" mean?Doubling the (sound) intensity is obtained by an increase of the (sound intensity) level of 3 dB.Doubling the sound pressure is obtained by an increase of the (sound pressure) level of 6 dB.Doubling the loudness feeling is obtained by an increase of the (loudness) level of about 10 dB.
How does the intensity of a sound wave change if the distance from the source is reduced by a factor of 4?
- 6 dB is incorrect. It will decrease by 12 dB.
How do you increase the intensity of sound waves from a radio?
Increase the volume.
How many times louder is an 80 dB sound compared to a 40 dB sound?
1000 times louder. Every 10 decibel, the intensity increases by a factor of 10.1000 times louder. Every 10 decibel, the intensity increases by a factor of 10.1000 times louder. Every 10 decibel, the intensity increases by a factor of 10.1000 times louder. Every 10 decibel, the intensity increases by a factor of 10.

How do you double decibels?
When doubling the field quantity factor by 2 the level increases by 6 dB. When doubling the energy quantity factor by 2 the level increases by 3 dB. When doubling the sound pressure value by 2 the level increases by 6 dB. When doubling the sound intensity value by 2 the level increases by 3 dB. The decibel (dB) is a logarithmic unit that indicates the ratio of a physical quantity relative to a specified or implied reference level. You usually don't double decibels - you double the factor (ratio). Look at the link "Subjectively perceived loudness (volume), objectively measured sound pressure (voltage), and theoretically calculated sound intensity (acoustic power)".
How can you increase intensity of a sound?
You can amplify the sound waves by microphone, amplifier and loudspeaker.
When a sound intensity increases by factor of 10 it's decibel reading increases by blank?
