A great sounding room is built by design. First, the size and shape is engineered specifically to suit the room’s purpose. We then consider the type of music being created, the preferred reverberation time, background noise level, and the predicted sound pressure level of the musical instruments or monitor system.  

The basic design stage is an architectural plan, using the same design tools as an architect.

In the next stages of design we use advanced prediction programs to plan the elements of construction, such as proper walls and windows. Prediction programs also assist in mapping the required acoustic absorption, whether it is broadband or to a specific frequency. This process is efficient and with the lowest possible margin for error.


Acoustic measurements are taken throughout the building process. These verify that results correspond to requirements, in terms of ambient noise insulation, appropriate reverberation times, and other parameters of room acoustics.

Architectural Design

Planning the suitable geometrical shape for a control room or live room. Keeping proper ratio between the width, length and height of the room.

Different shapes, ratio & room volume according to the music genre and predicted SPL.

Example #1.1:

3D plan of private music production complex with several studios, vocal booths and a spacious lounge.

Example #1.2:

A music production & recording complex that contains a performance hall, recording studio with several recording and control rooms.

Example #1.3:

Commercial recording studio with a control room, recording room, office, lobby and other facilities.


Acoustic Isolation

Acoustic isolation is needed to create a noise free recording & monitoring environment. Isolation is also important between a studio control to live rooms.

Example #2.1:

Sound Insulation Prediction of a double glazing system.

Example #2.2:

Impact Sound Prediction of a floating concrete floor.

Example #2.3:

Sound Insulation Prediction of a double wall system.


Acoustic Treatment 

Absorption is applied to walls and ceilings in order to reduce reverberation time and unwanted reflections. It can be used broadband or to a specific frequency range, such as bass traps.

Example #3.1:

Sound Absorption Prediction - broadband with extended low frequencies absorption.

Example #3.2:

Sound Absorption Prediction - dedicated low frequency absorption (bass trap).

Example #3.3:

Sound Absorption Prediction - low mid frequencies absorption.


Acoustic Measurement

During construction, different acoustic measurements are carried out. This is to ensure most accurate results.

Example #4.1:

Frequency Response & Impulse Response of a studio control room.

Example #4.2:

Reverberation Time measurement of a studio control room.

Example #4.3:

Magnitude & Phase response measurement of a sound system.
