Acoustic design

For whom we create acoustic design ?

We prepare project documentation – ACOUSTIC DESIGN – for the needs of:

• public investments in accordance with the Polish Public Procurement Law,
• Private Investors.

In case of every acoustic project, we analyse Customer’s needs, we closely consult proposed solutions with the User, so that the final project fully corresponds to the set design assumptions.

Interior acoustics

The interior acoustic design prepared by PAK includes:

• selection of shape, size and relation of room dimensions,
• selection and placement of finishing materials and acoustic systems
• creating the required acoustic parameters,
• maximum possible use of common building materials to achieve the desired interior acoustics,
• calculations and computer simulations showing values and frequency characteristics of acoustic parameters to be obtained, e.g. reverberation time, speech intelligibility.

Interior acoustics – acoustic adaptation of rooms, acoustic systems.

Noise protection

As part of sound protection design we develop:

• requirements concerning maximum levels of acoustic background in individual rooms,
• acoustic insulation of all partitions with specifications of partition structures,
• guidelines for all installations, in particular limiting ventilation noise,
• methods of limiting noise propagated by the object to the environment with respect to acoustic protection of the surrounding area and objects.

Noise protection – sound insulation, building acoustics, noise reduction.

Electroacoustic system

The design of an electroacoustic system consists of the following elements:

• design assumptions (qualitative, signal, functional)
• calculations and computer simulations of parameters describing operation of sound amplification system, e.g. sound pressure level, speech intelligibility, uniformity of sound coverage,
• block diagrams with connections between signal connections, equipment cabinets and devices as well as their layout,
• selection of all devices: microphones, preamplifiers, consoles, recorders, power amplifiers, loudspeakers, di-boxes, tripods, cables, matrixes, etc.
• guidelines for electrical supply of the systems,
• design description including system operation principle, list of devices, cable lines, etc,
• technical specification for the execution and acceptance of works including, among others, the specification of technical requirements for the entire system and individual devices,
• works take-off and investor’s cost estimate.

Stage Manager System

A complex stage manager system for a theater facility actually includes the designs of several systems.

As part of the stage manager system we design

• cable and wireless intercom communication,
• broadcasting announcements,
• eavesdropping on the stage and the audience,
• luminous confirmation of the action,
• silent banners,
• intermission bells,
• technical video preview,
• display of multimedia content (digital signage) in the foyer area.

Multimedia system

Multimedia systems designed for conference and lecture halls are integrated with their equipment to ensure high comfort of use. The basic functionality of such systems includes the appropriate presentation of images accompanying the lecture and sounding the voices of the speakers or audio material illustrating the presentation. In the case of more complex systems, we are also dealing with the integrated control of all audiovisual components as well as lighting and darkening of the room. As part of a comprehensive conference multimedia system project we perform:

• selection and placement of screens, projectors and speaker equipment based on computer simulations using a three-dimensional model of the room; optimization of the sound system to achieve adequate speech intelligibility,
• selection of lighting zones and control of room lighting,
• window shading system and its control.

Stage lighting

Stage lighting is also known as stage lighting, theatrical lighting, studio lighting. As part of the stage lighting design, we perform the selection and placement of lighting fixtures (profile spotlights, fresnels, floodlights, par’s, heads, follow spots, …) using computer simulations. We select and specify cabinets regulators, consoles, controllers, cabling.

Stage technology

Stage technology of buildings is a field that describes how a building such as a theater, concert hall, or any kind of performance venue should function. The general technology design defines, among other things, the guidelines for the layout of rooms, passenger and freight communication. Such documentation also contains solutions for transport and storage and refers to all workshops and specialist rooms. The technology design also defines the layout of galleries and technical platforms, and is responsible for providing the appropriate technical infrastructure for the operation of stage mechanics, stage lighting and sound systems.

Stage technology is most often a part of stage technology design concerning the specialized equipment of performance venues. Such a project concerns the provision of curtains, tripods, lecterns, stage floors, ballet floors, stage equipment, orchestra pit equipment, ..,

Stage mechanics

Stage mechanics. As part of the mechanical documentation we design mechanical devices used for performances and concerts:

• upper mechanics: curtains, lighting bridges, point-to-point winches,
• lower mechanics stage latches, piano latches, orchestra latches, rotary stages,

Documentation includes the selection, construction and arrangement of individual mechanical devices and electric or hydraulic drives depending on the chosen technology. The project usually also includes solutions for the control of mechanics.

Public address system

Public address systems, popularly known as broadcasting systems, are similar to classical stage electroacoustic systems in terms of design. The difference is that one public address system can serve many rooms in even very large facilities. Voice Evacuation Systems are in practice public address systems with increased requirements for reliability of operation and resistance to electromagnetic interference and any other effects resulting from fire hazards. When designing public address systems we perform the same operations as in classical electroacoustic systems.
