Pracownia Akustyczna

The acoustic project of the recording studio was focused mostly on the room acoustics and it included in particular:

• electrical wiring guidelines,
• soundproofing of the studio rooms,
• guidelines for the ventilation system project,
• digital modelling of the room acoustics,
• design of the construction of acoustical structures,
• arrangement of acoustical structures according to the room acoustics requirements.

Studio compound consists of a studio control room, recording room, vestibule and the lavatory.

A noise control project for the recording studio included:

• selection of dividing structures, which create the room sphere
• choosing the door carpentry.

We set the guidelines on noise control concerning sanitation facilities, especially ventilation, which had to be silent in itself and had to assure acoustic separation between the rooms.

The room acoustics was a priority.

The studio control room and the recording studio have proportions which fulfil a number of criteria, e.g. Bonello criterion and the EBU guidelines. We conducted a modal analysis, which provided the acoustic pressure distribution for the low tones. Based on the analysis we acknowledged the characteristics of sound propagation in the studio control room, which enabled the optimisation of the room acoustics through locating a proper listening position , studio monitors and acoustical structures.

In both rooms there are resonance acoustic structures tuned for the problematic frequencies for the room acoustics. The acoustical structures are put in a specific positions determined, among others, by a modal analysis made for the room acoustic project.

Realising the acoustics of both rooms, we used the acoustical structures created by Wave Acoustics company.

• On the back wall of the studio control room there is a broadband diffusing structure D7WB which is a fractal diffuser ( diffuser within the diffuser),
• On the side walls of the studio control room and recording room there are slotted acoustic structures created of the D7HF diffusers which create diffusion in the high tone range.

The ceiling of the recording room was adapted using the two-dimensional, "2D" acoustical structures which create diffusion within mid-frequencies.
