Instantaneous sound pressure refers to the pressure produced by sound waves at a given point in time. Synonyms for instantaneous sound pressure include acoustic pressure, sound intensity, and sound level. Acoustic pressure is a measure of the pressure created by sound waves and is commonly used in the study of acoustics. Sound intensity is a measure of the amount of sound energy that passes through a surface and is measured in watts per square meter. Sound level, on the other hand, is a measure of the intensity of sound and is often measured in decibels.
