WebLoudness. Loudness is not simply sound intensity!. Sound loudness is a subjective term describing the strength of the ear's perception of a sound. It is intimately related to sound intensity but can by no means be considered identical to intensity. The sound intensity must be factored by the ear's sensitivity to the particular frequencies contained in the sound. WebJul 8, 2024 · The intensity level is usually measured in watts/square meter and the value is usually very low for ordinary sounds. A sound with an intensity of about 5 ×10-5 (or 0.00005) watts/square meter translates to only about 80 decibels which os the volume of a food processor or blender. WebSound intensity may be measured in units of energy or work— e.g., microjoules (10 -6 joule) per second per square centimetre—or in units of … chandler shot dead
