ABOUT US

The ASD ADVANCED SOUND DESIGN GMBH stands for future-oriented sound design in office and communication rooms.
Our main areas of activity include:

DEVELOPMENT

Intensive research and development of highly efficient soundfiles for use in the ASD PRIVACY SYSTEMS to reduce speech intelligibility and promote acoustic privacy in modern working environments

PLANNING

Inventory analysis, creation of requirements profiles including change management for future-oriented spatial concepts

PRODUCTION

Production of room- and furniture-independent PRIVACY SYSTEMS, programming of adapted control software

INSTALLATION

Installation of the ASD PRIVACY SYSTEMS on site, individual assessment and commissioning of the system by our engineers with consideration of different room conditions and activity profiles

SOUNDS OF NATURE

A privacy system produces soft, harmonious, non-locatable background sounds to reduce intelligibility of words. The natural sounds used for this are familiar to us from everyday life.

What other people are talking about becomes less comprehensible. Your own conversations likewise become less easy for others to understand.

HOW DOES A PRIVACY SYSTEM WORK?

The Privacy System reduces the dynamic range (= contrasts) in a room acoustic enviroment.
EIN COMPARATIVE EXAMPLE OF CONTRASTS FROM EVERYDAY LIFE:

• Bright headlights
• Totale darkness
• Great contrast = High dynamic range

UNPLEASANT, DISHARMONIOUS SITUATION

• Bright headlights
• Steet lightning
• Low contrast = Low dynamic range

PLEASANT, HARMONIOUS SITUATION

HOW IT WORKS – BACKGROUND PHYSICS

Typical differences in speech sound levels over a given time.

A layer of sound playing in the background reduces the dynamic range appreciably.

The ASD Privacy System aids acoustic privacy and
reduces the intelligibility of speech in modern working environments.

The ASD Privacy System is a flexible system independent of any specific room parameters or furniture, which represents a modern, forward looking approach to room acoustics.

It creates within the room a natural, modulating, dephased and asynchronous beat, which is impossible to pinpoint and reduces intelligibility of the spoken word.

The system is able to achieve the target value (Appendix A ISO 3382-3) for distraction distance of rD ≤ 5 m.

PROJECT EXAMPLE

  • The installation of a privacy system was incorporated into the planning of the room acoustics and its effectiveness simulated on computer.
  • The planning of fixtures and fittings was done using a room acoustics 3D model.
  • The use of a privacy system significantly improved the different groups’ acoustic working conditions across the open-plan area.

SPEECH INTELLIGIBILITY
WITH NO PRIVACY SYSTEM

Within a radius of ten metres from the person speaking (red centre) up to 70% of what is being said is still intelligible.

SPEECH INTELLIGIBILITY
WITH PRIVACY SYSTEM

Beyond a radius of five metres from the person speaking only 50% or less of what is being said is still intelligible. The requirements of ISO 3382-3 in relation to distraction distance are fulfilled.
