Loudness is affected by sound pressure, frequency and its bandwidth, and duration (time). Loudness is a subjective measure, which is often confused with objective measurements of sound pressure in decibels with a sound level meter. A-weighting filters attempt to adjust sound measurements to correspond to loudness as perceived by an average human; however, loudness varies from person to person and cannot be really measured.
usually the pitch of the sound the frequency of the sound affect the loudness but as we say loud we mean how high the sound. In other terms when somebody shouts and we get irritated we would say "Not so loud" that means we refer to the person who is speaking loudly. this is known as the factors that affect sound
because sound waves spread out, intensity decreases with distance from the source.
Units used to measure loudness are Sone (loudness N) and Phon (loudness level L). Scroll down to related links and look at "Loudness - Wikipedia" and "Sound level change and the change of the respective factor of volume and loudness"
There are three factors influencing register they are: field, mode and tenor.
A normal conversation has a loudness (decibels level) of about 60 dB. As iy approached 70 dB it would be come loud.

The two factors that affect the loudness of sound are the amplitude of the sound wave, which determines the intensity of the sound, and the distance from the source to the listener, which influences how much the sound wave has spread out and dissipated.
The loudness of a gun is primarily influenced by factors such as the type of ammunition used, the size of the gun, the barrel length, and the amount of gunpowder in the cartridge. Additionally, the environment in which the gun is fired, such as indoors or outdoors, can also affect the perceived loudness.

Loudness, pitch and timbre are approximately the correlates of signal amplitude, frequency and frequency spectrum, respectively.
Sound intensity or acoustic intensity can be calculated from the objective measurement of the sound pressure. The loudness is a psycho-acoustic subjective feeling, which is difficult to measure.
The speed of sound is slower at higher altitudes because the air temperature is lower. The greater the amplitude, the louder the sound. It is your perception of the energy of a sound. What two factors affect the loudness of a sound

Resonance can affect the loudness of an instrument by amplifying certain frequencies, making certain notes or harmonics sound louder. This can contribute to the overall volume and tone of the instrument.
