Sound Intensity VS Sound Pressure

 

In acoustics, sound intensity and sound pressure are related but distinct measurements.

Variations in air pressure caused by vibrations are referred to as sound pressure. It is a measurement of the instantaneous force exerted by sound waves on a surface …

Acoustic Sound Pressure level

Sound pressure and sound pressure level are the variation in air pressure levels by sound vibrations. Typically expressed in pascals (Pa) or decibels (dB) and measures the amplitude or intensity of sound at a particular location. Sound pressure is …

Parallelepiped? What is it?

A parallelepiped is a geometric figure that resembles a rectangle in three dimensions. Each of its six surfaces is a parallelogram. A parallelepiped can be used to represent a sound source or an acoustic enclosure in terms of acoustic …

Line Source – What is It?

The behaviour of sound waves emitted by a long, linear source is referred to as line source sound propagation. In this instance, sound waves emanate from the source along a line or narrow segment, as opposed to a single …

Point Source – What is it?

The behaviour of sound waves emanating from a singular, localised sound source is referred to as point source sound propagation. In this instance, sound waves emanate from their source in a spherical or nearly spherical pattern.

When a sound is …

Reverberation Time and How to Measure It

Reverberation is the continuation of sound in an enclosed space after the source of the sound has ceased. Multiple reflections of sound impulses from the surfaces of the room, such as the walls, floor, and ceiling, produce reverberation. These …
