In a rectangular room, there are three types of acoustic resonances, commonly named: axial, tangential and oblique modes. The axial modes one-dimensional , give the bigger energetic contribution to the acoustic characteristics of a room; the acoustic waves spread in a direction parallel to one of the coordinate axis and the resonance frequencies are identified by the sets of three nz,0,0 , 0,ny,0 , 0,0,nz.

In tangent modes bi-dimensional , identified by the sets of three nx,ny,0 , 0,ny,nz , nx,0,nz , the sound waves that spread in directions parallel to coordinate axes have half the energy of axial modes, but their effects on the acoustic of the room remains sig- nificant. The oblique modes tri-dimensional , with a quarter of the energy of axial modes, are less important than the other two; with them the sound waves spread in oblique directions compared to ICSV22, Florence Italy July 1 The 22nd International Congress on Sound and Vibration coordinate axes and are identified by sets of three nx,ny,nz.
In region C there is a transition area, in this area diffusion and diffraction are dominant. It is approximately limited by frequencies fs lower and 4fs upper. The region D covers the higher audible frequencies, whose wavelengths are proper for the application of the geometrical acoustic rules; the statistic approach is possible.
The low frequency response of a room, modest in region A, increases thanks to resonances in re- gion B and is subject to diffraction and absorption in regions C and D. The Schroeder frequency known also as "cut off" or "cross over" frequency represents the limit between the region where modal characteristics linked to the particular room and the region of frequencies whose sound field takes on statistical characteristics.
All the rooms of the new studio have been analyzed from acoustic point of view; in this paper the Authors describe in detail the analysis of the recording Room A.
The whole project Fig. To realize the recording rooms and the control room, the technique of the room within a room RWAR , well-known as "box in the box", has been used.

With such technique, the walls have been covered with layers of rock wool and plas- terboard and they achieve a sound transmission loss index of 85 dB. The new inner partitions have been designed with a sandwich package with two layer of plasterboard filled to rock wool and they have a sound transmission loss index of 75 dB.
The plan and the position of the control room has been the starting point for the placement of the other three rooms and their visual connection. Preserving all the windows, we decided to place the control room in the side of the building oppo- ICSV22, Florence, Italy, July 2 The 22nd International Congress on Sound and Vibration site to the busy street, and the other rooms on a semicircle with the fulcrum area as the centre: rotat- ing clockwise starting from the control room, each room is connected with the former one through a wide visual field.
This allows an interplay among musicians even in separate rooms useful in the recording session of an ensemble of instruments. In a recording room of such dimension, is common a reverberation time T60 of about 0.
This makes easier the addition of digital reverberation or other special ef- fects to the tracks in a second step, during the mix down in the control room. Table 1. Dimensions of the Room A and range of frequencies characteristic of each region.

Philip Newell provides detail on the practical aspects of recording in various environments, not only exploring the complex issues relating to the acoustics but also providing real-world solutions.. You just clipped your first slide!There are modal calculators available on the web but they will provide a lot of information that is difficult to understand.
Contemporary designers would rather have a rectangle with proper ratios for a control room. For additional information, see the Global Shipping Program terms and conditions - opens in a new window or tab This amount includes applicable customs duties, taxes, brokerage and other fees. Audio Eng.
Alton Everest, Master Handbook of Acoustics So what are the reasons for the shapes you see in a recording studio? Technical Infrastructure Design For technical spaces to function properly, the equipment and control surfaces need a happy home, too, and that means having good cable management pathways, technical power and grounding systems, and adequate cooling.
