No, it is 10 times louder. dB is a logarithmic scale; every 10 dB, the intensity increases by a factor of 10. Thus, 10 dB is 10 times louder than 0 dB, 20 dB is 10 times louder than 10 dB, and 30 dB is 10 times louder than 20 dB.

A sound that is perceived as twice as loud requires what?
A 10dB (decibel) increase makes a sound that is perceived to be twice as loud.
Is intensity directly proportional to loudness?
No - since sound (hearing) operates on a logarithmic scale. So to be twice as loud a sound must be 10 times as "intense".
What is the intensity of a sound half as loud as 60dB?
60dB
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.
A sound that is perceived as twice as loud requires what?
A 10dB (decibel) increase makes a sound that is perceived to be twice as loud.
A sound that is perceived as twice as loud requires how much intensity?
Scroll down to related links and look at "Sound level change and the change of the respective factor of volume / loudness, sound pressure / sound intensity".
Is intensity directly proportional to loudness?
No - since sound (hearing) operates on a logarithmic scale. So to be twice as loud a sound must be 10 times as "intense".
What is the intensity of a sound half as loud as 60dB?
60dB
What properties of sound depend on the energy and intensity of the sound wave?
Its volume or how loud it is.

Would loud be a verb?
No, "loud" is not a verb. It is an adjective that describes the volume or intensity of a sound.
What property of sound depends on the energy and intensity of the sound wave?
Its volume or how loud it is.
What do we see that the amplitude of a wave produces?
The amplitude of a wave produces the intensity of the wave. With a light wave, it is the intensity of the light, with a sound wave, it is how loud the sound is
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.
Is a three dB difference in sound twice as loud?
No, 10 dB is perceived to be twice as loud, and requires 10 times the power.Doubling of the volume (loudness) should be perceived by a level difference of 10 dB − psychoacousticians say.Doubling the sound pressure (voltage) level corresponds to a measured level change of 6 dB.Doubling of acoustic power (sound intensity) level corresponds to a calculated level change of 3 dB.Scroll down to related links and look at "How many decibels (dB) is twice (double, half) or three times as loud?"
What is the Unit of measuring the intensity of sound?
Sound is measured in decibels, dB. Ten decibels (one Bel) sounds twice as loud as another sound. One decibel is the amount of sound just distinguishably louder than another sound. Named after A G Bell of telephone fame.
