Acoustics and psychoacoustics

Every project is customized and at the core of our approach lies the principle of psychoacoustics, the study of how people perceive and respond to sound. Our primary goal is to ensure optimal outcomes that seamlessly integrate with the venue’s overall acoustics, its occupants, and the surrounding acoustic environment.

Our Process

To secure optimal outcomes, we oversee the entire process, from pre-study and conceptualization, all the way to hardware implementation and sound content creation. All sound production is managed in-house in our dedicated studio facilities.


Throughout the installation process, we ensure that speakers are strategically positioned, taking into account the flow of people within the room and the overall acoustic environment. Our focus remains on channeling the appropriate audio to its designated location, fine-tuning the volume, and the programming to align with the intended functionality. Finally, we verify that everything is where it should be, that the customer is satisfied and knows how to use the system.

Technical know-how

Our ability to actualize our sound concepts and evoke impactful auditory experiences is attributed to our utilization of appropriate hardware and technology. In the technical planning phase, we choose both standard and specialized technology tailored to your specific project. When necessary, we incorporate cutting-edge technology. Through the integration of tools such as sound showers, vibration speakers, and sensors we enable the realization of concepts that surpass the limitations of conventional sound technology.

Managing sound installations

Our commitment continues beyond the installation phase, extending to ongoing support tailored to your specific requirements. We oversee management of the sound concept and ensure its continual relevance, utilizing our user-friendly sound platform Twang. If required, we provide the option to refresh audio content to follow seasonal changes or specific campaign objectives that you might have.

Regardless of the scope of the project, our goal is always to offer a solution that prioritizes the user experience. We tune the world!
