Loudness is the perception of the strength or intensity of a sound. It is influenced by both the amplitude of the sound wave and the sensitivity of the human ear.

Loudness is measured in decibels (dB), which quantify sound pressure level.
Human hearing ranges from approximately 0 dB, the threshold of hearing, to around 120-130 dB, where sounds become painfully loud.
The perceived loudness doubles with every increase of about 10 dB.
Frequency affects loudness perception; humans are more sensitive to frequencies between 2,000 and 5,000 Hz.
Loudness is subjective and can vary from person to person based on individual hearing capabilities.
