Acoustic absorbtion panels
Absorption refers to the absorption of sound waves by a material. The absorption is the "missing piece", when comparing the total reflected and transmitted energy with the incident energy.
It is the property of a material that changes acoustic energy into usually heat energy. A material or surface that absorbs sound waves does not reflect them. Absorption of a given material is frequency dependent as well as being affected by the size, shape, location, and mounting method used.
A sound absorber is normaly a porous material e.g. mineral wool, glass wool or polyurethane foam, but also Micro Perforated plates work as sound absorbers.
Both of these studios are using Acoustic absorbtion panels:-

Sound diffuser
Sound diffuser A sound diffuser sends the audio-waves in many different directions. This is good if you don't want an entirely dry room, but want some sound reflections for recording, say, drums.
A sound diffuser is not to be mixed up with sound absorber. While a sound absorber absorbs the audio-waves, the sound diffuser sends the audio-waves in many different directions. This is good if you don't want an entirely dry room, but want some sound reflections for recording, say, drums.
The more expensive diffusers sends audio waves in different direction based on frequency.
Acoustical wall and ceiling panels
Acoustical wall and ceiling panels Acoustical wall and ceiling panels can be constructed of many different materials and finishes. The ideal acoustical panels are those without a face or finish material that interferes with the acoustical infill or substrate. Fabric covered panels are one way to maximize the acoustical absorption. The finish material is used to cover over the acoustical substrate. Mineral Fiber Board, or Micore, is a commonly used acoustical substrate. Finish materials often consist of fabric, wood or metal. Fabric can be wrapped around substrates to create what is referred to as a "pre-fabricated panel" if laid onto a wall, and require no modifications. Prefabricated panels are limited to the size of the subas "on-site acoustical wall panels" This is constructed by "framing" the perimeter track into shape, infilling the acoustical substrate and then stretching and tucking the fabric into the perimeter frame system. On-site wall panels can be constructed to work around door frames, baseboard, or any other intrusion. Large panels (generally, greater than 50') can be created on walls and ceilings with this method. Wood finishes usually
The "Live Room"
The "Live Room" Recording studios generally consist of three rooms: the studio itself, where the sound for the recording is created (often referred to as the "live room"), the control room, where the sound from the studio is recorded and manipulated, and the machine room, where noisier equipment that may interfere with the recording process is kept. Recording studios are carefully designed around the principles of room acoustics to create a set of spaces with the acoustical properties required for recording sound with precision and accuracy. This will consist of both room treatment (through the use of absorption and diffusion materials on the surfaces of the room, and also consideration of the physical dimensions of the room itself in order to make the room respond to sound in a desired way) and soundproofing (to provide sonic isolation between the rooms). A recording studio may also include additional rooms, such as a vocal booth - a small room designed for voice recording, as well as one or more extra control rooms.
