loudness measurement

Loudness measurement quantifies how we perceive the volume of sound, taking into account factors like frequency and duration. Unlike simple volume levels, loudness reflects the human ear's sensitivity—it's how loud something seems to us. Measurements often use units like sones or phon, which adjust for how different frequencies sound louder or softer to our ears. This helps in audio quality control, broadcasting, and hearing research by providing a more accurate representation of perceived loudness, ensuring consistent audio levels across various sounds and environments.
