-- A difference of 20 dB means the louder one is delivering 100 times as much
power as the softer one is.
-- The power delivered by any sinusoidal phenomenon is usually proportional to
the square of the amplitude. So the amplitudes would have to be in the ratio of
10 to 1. The louder one has 10 times the amplitude of the softer one.

How do the amplitudes of a decibel sound and a 100-decibel sound compare?
The power or intensity of the louder one is 10 billion times the power or intensity of the softer one. Since the power or intensity is typically proportional to the square of the wave amplitude, the amplitude of the louder one is a mere 100,000 times the amplitude of the softer one.

Do loud sounds have a high amplitude?
Strictly speaking, noise is merely unwanted sound, irrespective of the loudness.The 35 dB sound level from an air-conditioner may be noisy, whereas the 100 dB roar alongside the speedway may well be desired (and dangerous to your ears).
How is the energy of a sound wave related to its measured value on a decibal scale?
The decibel scale is a logarithmic scale. An increase of 10 points on the decibel scale means that the energy increases by a factor 10; an increase of 20 decibels means an energy increase by a factor of 10 x 10 = 100, etc.
A wave in the ocean has amplitude of 3 m Winds pick up suddenly increasing the wave's amplitude to 6m How does this change in amplitude affect the wave's frequency and the amount of energy it tra?
it doubles so by 100%

How does the intensity of a 40-decibel sound compare to the intensity 20-decibel sound?
100 times. Each bel (10 decibels) is ten times as loud thus 20 to 40 is 100 times.
How does intensity of a 40 decibel sound compare to intensity if a 20 decibel sound?
The 40dB sound is (40 - 20) = 20 dB louder than the 20 dB sound.20 dB louder = 10(20/10) = 102 = 100 times louder
How many times louder is a 20 decibel sound than a 0 decibel sound?
100 times louder. You will hardly hear a 20 db(SPL) sound at all.
What unit of measurement is used to compare the intensities of different sounds?
The unit is the decibel, based on a larger unit called a bel. The decibel is measured as a magnitude on a logarithmic scale, and has no dimension as such. An increase in the numerical value therefore indicates an exponential (logarithmic) increase in the actual intensity or power. Example : an increase of 3 dB is approximately twice the power, an increase of 10 dB is 10 times the power, and an increase of 20 dB is 100 times the power.
What is the sound Lovebird makes?
A lovebird has no decibel. The closer your ear is to a sound source the louder it will be. We measure the sound pressure level (SPL) in decibels at a distance. Laymen are happy knowing a fantasy "decibel of 100 dB". But without any distance such value is really nonsense.
How will an increase in amplitude and power affect dB?
The decibel (dB) scale is logarithmic. An increase of power by a factor of 10 is an increase of +10 dB. If power increases by a factor of 100, that is equivalent to +20 dB.The decibel (dB) scale is logarithmic. An increase of power by a factor of 10 is an increase of +10 dB. If power increases by a factor of 100, that is equivalent to +20 dB.The decibel (dB) scale is logarithmic. An increase of power by a factor of 10 is an increase of +10 dB.

What happens when decibel levels go down?
The sound becomes harder to hear. Unless you are above the threshold of pain in which case I guess the sound becomes easier to hear. The decibel system was designed so that the thresold of human hearing is just about at 0 dB and the threshold of pain is at about 135dB0. Where the power doubles for every 3 dB points. Hence it is a logarithmic scale. A 20dD sound is not half as loud as a 40dB sound but roughly 100 times quiter.
What is the softest sound in the world?
20,000 Hz (20kHz) is the (ideal) highest FREQUENCY that a healthy human ear can hear. With regard to loud sounds, a sound LEVEL of 120 decibel (dB) causes pain, and a level of 140 dB causes deafness.
