Experience optimal room acoustics for every need
The acoustics of a room play a key role in how comfortable we feel in it. They affect volume, speech intelligibility, and how we perceive the space as a whole.
Why is good room acoustics essential?
Effective room acoustics enhance communication quality in offices, schools, and other environments. They reduce noise levels, improve speech intelligibility, and create a pleasant atmosphere.
According to the World Health Organization, high indoor noise levels can increase the stress hormone cortisol by up to 50%. Long-term noise exposure is linked to health issues such as high blood pressure, sleep disorders, and heart disease.
The Workplace Acoustics Survey shows that poor room acoustics can reduce office productivity by up to 66%. In open-plan offices, noise and echoes are often perceived as the biggest distractions.
Good room acoustics reduce noise and stress, supporting the well-being and health of the people in the space.

Causes of poor room acoustics
Room acoustics are largely influenced by the size, shape, and materials used in a space. These factors determine how sound propagates, is reflected, and absorbed, and thus shape the acoustic quality.
Influence of room size and shape
- Room size: Large rooms often create long reverberation times, as sound takes longer to travel from one surface to another. Sound-absorbing materials can reduce this effect.
- Room shape: Irregular shapes scatter sound waves and help avoid standing waves, which often cause disturbing resonances in rectangular rooms.
Hard surfaces: Materials like concrete walls or tiles strongly reflect sound and offer little sound absorption, resulting in reverberation.
Lack of absorption materials: Carpets, curtains, or specialized wall coverings absorb sound and are often missing in rooms that feel acoustically unpleasant.
Unfavorable room shapes: Long, narrow hallways and rectangular rooms often lead to uneven sound distribution and resonances.
Sound-reflecting materials: Using reflective instead of absorptive materials increases reverberation and reduces clarity.
Reflective surfaces in small rooms: Closely spaced hard surfaces reflect sound and cause acoustic disturbances.
Obstructive furniture: Furniture can either block or reflect sound, negatively impacting the acoustics.
Room usage: Different uses such as offices, concert halls, or living rooms require specific acoustic measures. Inadequate acoustics impair functionality and the listening experience.
Possible improvements to room acoustics
Through targeted planning and the use of specific acoustic measures, acoustic weaknesses can be corrected and a pleasant room acoustic environment can be created. Here are some approaches:
Control of reverberation time: The reverberation time should be adjusted according to the room’s use. Offices and classrooms benefit from shorter reverberation times for improved speech intelligibility. Concert halls require longer reverberation times to achieve musical richness.
Adjustment of absorption area: The equivalent absorption area of the room can be increased using sound-absorbing materials such as carpets, curtains, and acoustic panels to specifically reduce reverberation.
Improvement of speech intelligibility: In lecture halls and auditoriums, targeted adjustment of the sound spectrum and reflections improves speech intelligibility.
Specific acoustic parameters for concert halls: In concert halls, parameters such as clarity, bass ratio, and EDT (Early Decay Time) are optimized to create detailed and harmonious sound quality.
Resonators for controlling problem frequencies: Resonators can be used to dampen specific problematic frequencies that often occur in rooms with certain dimensions.
Custom design and visual integration: Acoustic elements such as acoustic images, transparent features, and fabric panels can be designed not only functionally but also aesthetically to complement the room design.
Precise sound distribution through reflectors: Reflectors can be positioned to distribute sound in a targeted way and create a uniform sound field in the room. This improves both the acoustics and the perception of spatial sound.
Frequently asked questions about room acoustics
Here we answer important questions on the topic of room acoustics and explain how good acoustics can improve the well-being and functionality of spaces.
What is meant by room acoustics?
Room acoustics is the field that studies the propagation and perception of sound in enclosed spaces. It analyzes how sound waves are reflected, absorbed, and distributed in the room, and how these factors influence the acoustic experience. A well-tuned room acoustics ensures clear and natural sound reproduction. Poor room acoustics can lead to echoes, reverberation, or unpleasant noise levels that can significantly disrupt the perception of the space.
Room acoustics play a role in many areas – such as concert halls, offices, classrooms, and living spaces. For optimal sound quality and a pleasant acoustic environment, methods such as sound absorption, diffusion, and targeted room design are employed.
How does building acoustics affect room acoustics?
Building acoustics play a central role in room acoustics, as they influence the propagation and perception of sound within a space. Through targeted structural measures such as the choice of suitable building materials, wall and ceiling constructions, sound reflection, absorption, and transmission can be specifically controlled.
Good building acoustics help control reverberation time, reduce disturbing reflections, and improve sound insulation between rooms. In this way, unwanted noise is minimized, which enables clear and pleasant acoustics.
Whether living spaces, offices, or event halls – well-designed building acoustics provide the basis for a functional and comfortable sound environment.
How does sound arise?
Sound arises from vibrations that create pressure fluctuations in the air. A sound source, such as a vibrating string, sets air molecules in motion. These movements generate sound waves that propagate through the air and eventually reach the human ear. There, the pressure fluctuations are converted into electrical signals, which the brain interprets as sound.
Sound can also be transmitted in solid media such as water or solids, where the vibrations of the particles enable propagation. The frequency of the vibrations determines the pitch: the human ear perceives frequencies between about 20 Hz and 20,000 Hz.
Can I also make use of your services as a private individual?
Yes, our services are also available to private individuals! Whether you want to improve the room acoustics in your home, set up a home theater, or reduce disturbing noises – we are happy to support you with your individual wishes and requirements.
How much does an acoustic room optimization cost?
The cost of an acoustic room optimization varies depending on:
- Room size
- Scope of measures
- Type of acoustic solutions
- Individual requirements
Industrial and commercial enterprises with larger rooms often have to expect higher costs, especially with special soundproofing requirements. For private individuals who want to optimize smaller rooms, the costs are generally lower.
For an exact cost estimate, we recommend contacting us directly so that we can create an offer tailored to your requirements and the complexity of the project.
How long does it take to improve room acoustics?
The duration of the room acoustics optimization depends on various factors:
- Room size
- Type and scope of the measures
- Complexity of the installation
- Availability of the materials
Smaller measures, such as placing sound absorbers, can often be implemented quickly. More extensive projects, such as the installation of soundproof walls or the adjustment of the room structure, require more time.
For larger industrial and commercial spaces or special requirements, a longer timeframe is usually necessary. Smaller private projects can often be realized in a shorter time.
A thorough planning and analysis in advance is recommended in order to develop efficient solutions. The exact duration can best be determined in a consultation in order to define a realistic timeframe for the specific requirements.
Important terms in room acoustics
- Sound: Mechanical waves that move through the air and are perceived by the human ear. The control of sound reflection and damping is central to good room acoustics.
- Reverberation: The persistent perception of a sound, even when the source is no longer active. It is caused by multiple reflections on room surfaces such as walls and ceilings and can affect the clarity of the acoustics.
- Noise level: The intensity of sound, measured in decibels (dB). High noise levels can be disturbing and impair the intelligibility of speech and music.
Which parameters exist in room acoustics?
Reverberation time (T60)
Reverberation time indicates how long it takes for the sound level in a room to decay by 60 decibels. An appropriate reverberation time is important for speech intelligibility and sound quality. According to the Journal of the Acoustical Society of America, the ideal reverberation time for speech is between 0.6 and 1.0 seconds, while for music rooms it should be between 1.5 and 2.5 seconds in order to achieve a full sound.
Sound absorption coefficient (α)
The sound absorption coefficient describes how well materials absorb sound energy. Materials with a high absorption coefficient reduce reverberation and unwanted noise in the room.
Speech Transmission Index (STI)
The STI evaluates the intelligibility of speech in a room. It takes into account factors such as background noise and reverberation in order to assess the quality of speech transmission.
Room impulse response (RA)
The room impulse response shows the temporal distribution of sound in the room and provides information about how sound waves are reflected and distributed.
Loudness level (N)
The loudness level takes into account the frequency sensitivity of the human ear and describes the subjective perception of loudness in the room.
Room sound (G)
Room sound describes the spatial perception of sound and depends on the distribution of direct sound and reflected sound waves, which together shape the acoustics in the room.
