The word loudness belongs to psycho acoustics and tells how we feel this sound, that is not measuring the sound like we do with a sound pressure meter. Listening to music means motion to the ear drums. Only sound pressure moves the ear drums. The energy or the sound intensity is much less important here. Sound intensity belongs more to the noise fighters.
From a wave model perspective, the intensity of a sound (i.e. its "loudness") is dependent on the amount of energy that the sound wave carries. The energy of the wave is proportional to the amplitude, how far the wave goes up and down. Thus, the intensity of voice is dependent on how much force you applied to the air passing through your vocal cords, thus displacing them more (thus a bigger amplitude). Try it, put your hand to your throat and feel which sound is more noticeable (when you whisper, or when you shout).
Loudness is the quality of a sound that is the primary psychological correlate of physical strength or amplitude. Loudness is a subjective felt impression and is in some way related to the objective measure of the sound pressure. Neither our ear drums nor the microphone diaphragms can convert acoustic intensity. Therefore only use the sound pressure for measuring. To measure the loudness feeling is a difficult thing. The loudness of 1 sone equals the loudness level of 40 phons (at 1 kHz).
The loudness of a sound is related to how much energy is transmitted to the air. Clapping your hands transmits a small amount of energy. Detonating a stick of dynamite transmits MUCH more energy. The amplitude of the sound wave is much greater, and the noise, louder.
Its volume or how loud it is.
Sound intensity I is a measure in W/m² that is a energy quantity of sound.Loudness is the quality of a sound that is the primary psychological correlate of physical strength. Better use the sound pressure in pascals (Pa = N/m²) because this sound field quantity makes the effect of moving our ear drums.Measuring intensity and feeling the loudness does not relate good. Perceived loudness varies from person to person and cannot be measured this way.A A-weighting filter attempts to adjust sound measurements to correspond to loudness as perceived by the average human.Units used trying to measure loudness are Sone (loudness N) and Phon (loudness level L).
Amplitude is the energy of a sound wave, which we also call Loudness

No, the amplitude of a wave is related to the magnitude of its energy, not its perceived loudness. In sound waves, the perceived loudness is determined by the intensity of the sound, which is related to the wave's amplitude and the distance the sound travels. So a higher amplitude wave may not necessarily sound quieter.
to its amplitude. The greater the amplitude of a sound wave, the louder it will be perceived. This is because amplitude is directly correlated with the amount of energy carried by the wave, impacting the intensity of the sound.
It is most closely related to its amplitude (loudness, magnitude) because this is determined by the energy used to create the sound. Louder noises generally take more energy to create.
When the intensity of sound decreases, the amplitude of the sound waves decreases. This means that the sound waves carry less energy, resulting in a softer and quieter sound. The perception of loudness is directly related to the intensity of sound.
The human perception of sound intensity is called loudness. Loudness is influenced by the amplitude or energy of the sound wave and is measured in decibels (dB).
From a wave model perspective, the intensity of a sound (i.e. its "loudness") is dependent on the amount of energy that the sound wave carries. The energy of the wave is proportional to the amplitude, how far the wave goes up and down.

Loudness is the quality of a sound that is the primary psychological correlate of physical strength (amplitude). It is a feeling, which is neither the sound pressure as field quantity nor the acoustic intensity as energy quantity. Scroll down to related links and look at "Loudness - Wikipedia".
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.
Sound is a mechanical wave. This means it needs a material medium to travel through. The loudness ie the intensity of sound is directly proportional to the square of the amplitude. As the sound wave passes through, due to elasticity of the medium the energy will be lost and so the amplitude gets decreased. So at far distance the sound intensity will be very feeble.
No, the energy of a mechanical wave does not depend on the amplitude of the wave. The energy is determined by the frequency and the medium through which the wave is traveling. Amplitude only affects the intensity or loudness of the wave, not the total energy.
