Amplitude squared is the amount of energy in a wave.
The simplest calculations would be for a string wave.
Amplitude ratio to dB conversion:For amplitude of waves like voltage, current and sound pressure level:GdB = 20 log10(A2 / A1)A2 is the amplitude level.A1 is the referenced amplitude level.GdB is the amplitude ratio or gain in dB.dB to amplitude ratio conversion:A2 = A1 · 10(GdB / 20)A2 is the amplitude level.A1 is the referenced amplitude level.GdB is the amplitude ratio or gain in dB.
The amplitude is 1.
The amplitude is ' 1 ' .
That if the original amplitude was A then it is now 2*A.
Amplitude is just themaximum displacementof a wave:
Intensity of a wave is proportional to the frequency squared and amplitude squared based on this formula; I=1/2pw^2A^2V where p is the density of the medium, w is the angular frequency and A is the amplitude and V is the wave velocity. So, everything else remaining constant, decreasing the amplitude will decrease a waves intensity. Example decreasing the the amplitude by a factor of 4 will decrease the wave intensity by a factor of 8.
As the amplitude of a wave increases, the energy increases. In general terms the energy transported by a wave is proportional to the amplitude squared.
They are all measueres of sound waves. Amplitude is the term for the maximum difference in pressures between the peaks and troughs of a sound wave. Intensity is a measure of the energy content of a wave, and is proportional to amplitude squared. The decibel is an anthropic (based on human senses) measure of sound intensity, proportional to the logarithm of intensity.
Usually, people are asking as if there is just "the" amplitude in sound waves in air. The loudness perception of a sound is determined by the amplitude of the sound waves − the higher the amplitude, the louder the sound. Which amplitude of sound (sound amplitude) do you mean? There are: amplitude of particle displacement ξ, or displacement amplitude amplitude of sound pressure p or pressure amplitude amplitude of sound particle velocity v, or particle velocity amplitude amplitude of pressure gradient Δ p, or pressure gradient amplitude. Furthermore, think of the amplitude of the oscillation of a string. The maximum magnitude of the deflection of a wave is called amplitude. Look at link: "What is an amplitude?"
There is not only "one" amplitude. There is an amplitude of particle displacement ξ, or displacement amplitude, an amplitude of sound pressure p or pressure amplitude, an amplitude of sound particle velocity v, or particle velocity amplitude, an amplitude of pressure gradient Δ p, or pressure gradient amplitude. If the "sound" inceases, the "amplitude" also increases.
The term for maximum displacement is the amplitude of the wave.

The loudness has to do with the sound field quantity called sound pressure or sound pressure level (SPL). The sound intensity or acoustic intensity means the sound energy quantity. Our ears and the microphone diaphragms are moved by the amplitude of sound pressure variations. Intensity I = sound pressure squared p2.
amplitude increases (louder the sound is, bigger is the amplitude)

The amplitude to a wave is high.
