Architecture and construction - expertise for optimal sound
Good acoustics are not a luxury, but a fundamental prerequisite for comfort, health, and productivity in modern buildings. Whether in living spaces, offices, schools, or public facilities – acoustic quality significantly influences our well-being and performance. At the same time, challenges are increasing: Open-plan concepts, lightweight construction methods, increasing noise sources, and high user expectations require specialized expertise. We are your experienced partner for all aspects of building and room acoustics. We offer you in-depth analyses, precise planning, and customized solutions for an optimal acoustic environment.
We understand the complex acoustic requirements and support you in overcoming them
Requirements for sound insulation
Legal requirements such as DIN 4109 define minimum requirements for protection against noise from neighboring apartments (airborne and impact noise) and from outside. However, there are often additional requirements for increased comfort or specific requirements due to use (e.g., hospitals, hotels). Meeting these requirements requires careful planning of components such as walls, ceilings, windows, and doors, as well as their connections. Errors can lead to noise pollution and legal disputes.
Optimal room acoustics
In spaces where communication or concentration is important (offices, schools, seminar rooms, restaurants), good room acoustics are crucial. Excessively long reverberation times lead to poor speech intelligibility and a tiring noise level. The aim is to create a pleasant listening environment through the targeted arrangement of sound-absorbing and sound-scattering surfaces that suits the intended use without negatively impacting the architectural design.
Noise reduction from building services
Modern buildings have complex technical systems (ventilation, heating, refrigeration, elevators, plumbing). These can generate significant noise and be transmitted via airborne or structure-borne sound into rooms requiring protection. The challenge lies in minimizing this noise directly at the source and effectively interrupting the transmission paths through appropriate insulation and decoupling measures to avoid disturbing the peace and quiet of the occupants.
Vibration protection & structure-borne sound
Vibrations from external sources (e.g., railway lines, road traffic) or internal systems (machinery, fitness equipment) can propagate as structure-borne sound through the building structure and be re-radiated elsewhere as disruptive airborne sound or be directly felt as a shock. Analyzing these transmission paths and planning effective vibration isolation measures (e.g., elastic mountings) are essential, especially for sensitive uses or in densely built-up areas.
Our services in architecture and construction
Acoustic planning & simulation
Based on your requirements and architectural plans, we prepare detailed sound insulation certifications in accordance with DIN 4109 and other relevant standards. Using computer-aided simulations, we predict room acoustic conditions (e.g., reverberation time, speech intelligibility index (STI)) or outdoor sound propagation and optimize the planning through virtual testing of various measures.
Acoustic measurements & analyses
Using calibrated measurement technology, we conduct precise on-site measurements: airborne and impact sound insulation between rooms, reverberation times for assessing room acoustics, noise levels from technical systems, and noise emissions from external sources. The results are used to verify requirements, analyze the root causes of problems, or serve as the basis for expert opinions.
Development of sound insulation concepts
We analyze sound transmission paths and design specific component structures and detailed solutions to achieve the required sound insulation. This includes the selection of suitable materials and constructions for walls, ceilings, floors, windows, and doors, as well as the planning of sound decoupling and sealing systems.
Room acoustic design
We develop concepts to improve audibility and reduce noise levels in rooms. This includes calculating the required sound absorption, selecting and strategically placing absorbing materials (e.g., acoustic ceilings, wall panels, furniture), and, if necessary, using sound-scattering elements (diffusers), tailored to the use and aesthetics of the room.
Acoustic material testing & parameter determination
We precisely determine the acoustic properties of building materials in the laboratory. Using standardized procedures, such as impedance tube measurements, we determine parameters such as sound absorption coefficient, sound reflection coefficient, and acoustic impedance. This enables independent verification of manufacturer data, the characterization of innovative materials, and the informed selection of the optimal material for your project's specific acoustic requirements.
Your added value through our services
Invest in the acoustic quality of your project, because professional planning pays off in many ways. You gain legal certainty, as we ensure reliable compliance with all relevant sound insulation standards and legal requirements. This not only protects you from complaints but also avoids costly defects and potential conflicts through forward-looking planning that eliminates typical sources of error right from the start.
In addition, we create environments that maximize the well-being and comfort of their users. Whether it's focused work in the office, undisturbed peace and quiet in living spaces, or clear intelligibility in meeting and event venues – we ensure the right acoustics. This demonstrably leads to increased productivity and concentration and promotes effective communication.
Ultimately, a high acoustic standard is a recognized quality feature that sustainably increases the value of your property.
