More amplitude means more loudness of the sound.
The loudness of a sound depends on the amount of energy it takes to make the sound and the distance from the source of the sound.

The loudness of a sound (or intensity) corresponds to the sound wave's amplitude. The amplitude of a wave is the distance from the midpoint of the wave to a high-point (crest) or low-point (trough).
Loudness is a word from psychoacoustics. It is the quality of a sound that is the primary psychological correlate of physical strength or amplitude. Loudness is a really subjective measure. It is often confused with objective measures of sound pressure or sound intensity. The perception of loudness varies from person to person, therefore it cannot be universally measured using any single metric. Loudness is also affected by parameters other than sound pressure, including frequency and duration.

Its loudness at a particular distance
There is really no standard distance from the sound source where the sound pressure level (SPL) is measured.
The amplitude of the sound waves. (the distance it makes the particles move)
It is less loud. Frequency affects what we hear as pitch. Amplitude affects volume.

Feelings of loudness are different from person to person. So don't talk of "measuring" the "loudness".For psycho acoustic values we have units to express loudness:Sone (loudness N) and Phon (loudness level L).You can really measure the sound pressure with a sound pressure level meter. That is measured in dB SPL. Loudness is a subjective measure but sound pressure is an objective measure. But that is different. Don't mix it up. Scroll down to related links and look for more on decreasing of sound pressure with distance.
Feelings are different from person to person. So don't talk of "measuring" the "loudness". You can really measure the sound pressure with a sound pressure level meter. At 8 ft from the speaker sound pressure level (SPL) is 28 decibels. What is loudness 4 ft from the speaker? You get 6 dB more level at half the distance r = 1/2, that is 34 dB. The sound pressure varies with distance 1/r from the sound source. There is nothing squared! Scroll down to related links and look at "Sound pressure p and the inverse distance law 1/r".
