Sound

Sound: Sound travel and can be heard when they reach a person's or animal's ear. Inaditon to this sound is nothing then a vibration that travels in air it cannot however travel through a vacuum and there is no sound in space as the vibrations can't travel as there is no air to let it travel.

Acoustics:  This is either the way a building and or room transmits / allows sound to travel in it. It can also be the physical concentration of sound in a given place, this can be an amp and or electric acoustic guitar thes are all the forms of acoustics relating to sound movement and concentration.

Interior acoustics:This is airborne sound inside rooms,i.e how it propagates and interacts with the room's surface and objects. But it's also about our precapton of the rooms acoustic properties. 

Surface properties: This is how well a given surface absorbs sound and or how an object / material interacts with sound vibrations.

Reverberation: Reverberation, in psychoacoustics and acoustics, is a persistence of sound after the sound is produced. A reverberation, or reverb, is created when a sound or signal is reflected causing a large number of reflections to build up and then decay as the sound is absorbed by the surfaces of objects in the space – which could include furniture, people, and air.

Studio acoustics: controlled environment: An isolation booth is a standard small room in a recording studio, which is both soundproofed to keep out external sounds and keep in the internal sounds, and like all the other recording rooms in sound industry, it is designed for having a lesser amount of diffused reflections from walls to make a good sounding room.
