Modernes Großraumbüro mit Glastrennwänden und akustischen Absorbern. Mehrere Arbeitsplätze sind in verschiedenen Kabinen angeordnet.

The sound insulation of all Strähle partition wall and Kubus products is the most important feature. Good sound insulation is the decisive factor for a concentrated working atmosphere. In modern offices in particular, the important things are the acoustic separation of communicative areas and zones for meetings, and discretion.

Großes, modernes Büro mit natürlichen Lichtquellen. Mitarbeiter arbeiten in einem offenen Grundriss mit Glaswänden und einem Industrie-Look. — Modern working environments place high demands on room acoustics. Open-plan office layouts encourage communication and collaboration, but at the same time increase noise levels.

Why is soundproofing so important in the office?

Noise is one of the most common sources of disruption in the workplace. Even brief interruptions caused by conversations or telephone calls can affect concentration. A well-designed soundproofing scheme not only improves speech intelligibility and privacy, but also enhances staff wellbeing.

This is particularly important in:

Open-plan offices
Meeting rooms
Focus and think tanks
Telephone and video conference rooms
Management and HR offices

Sound insulation and sound absorption

Sound insulation comprises two key factors: sound insulation prevents the transmission of sound between two rooms. It ensures that conversations and noises do not escape to the outside. Sound absorption reduces sound reflection within a room. This shortens reverberation times and improves speech intelligibility. It is only the interplay of both factors that creates high-quality room acoustics.

Key performance indicators

Various performance indicators are used to objectively assess the acoustic performance of partition wall systems:

R_w	Describes the sound insulation of a building component under test bench conditions.
R'_w	Describes the sound insulation actually achieved when the component is installed on site.
D_nT,w	Evaluates sound transmission between two rooms under real-world conditions.

Which soundproofing solution is the right one?

Soundproofing requirements vary depending on the use of the room:

Use	Recommended sound insulation
Meeting room	high
Management office	high
Project office	medium
Focus room	very high
Telephone booth	very high

Strähle’s modular room systems allow different requirements to be met flexibly, without compromising on a consistent design. The test bench data below provide an overview of the acoustic performance of the various Strähle systems. The appropriate solution can be selected depending on the room layout and requirements.

System 2000	R_w = 30 - 56 dB
System 2000_Nature	R_w = 42 - 52 dB
System 2300	R_w = 42 - 54 dB
System 3400	R_w = 32 - 40 dB
System 3400_Plus	R_w = 32 - 40 dB
System 3500	R_w = 40 - 47 dB
System T	R_w = 41 - 48 dB
Kubus I	D_n,T,W = 28 - 32 dB (approx R`_w 34-39 dB)
Kubus II	D_n,T,W = 34 dB ( approx R`_w 42 dB)

FAQs

Yes. Acoustic elements are also suitable for open-plan offices, as they reduce reverberation and minimise noise propagation in the space. However, these measures also improve the clarity and intelligibility of speech, which can lead to problems as colleagues focusing on their work may become distracted. Consequently, we recommend a special mix of sound absorbing and sound shielding measures for open-plan offices. The basic equipment provides sound absorbers to reduce the reverberation time, and an additional zoning system uses our partition wall systems to ensure that the clarity of speech is not so improved that conversations are distracting for colleagues.

Yes. Acoustic elements are a particularly good idea for meeting rooms, as they reduce reverberation and significantly improve speech intelligibility. This ensures that discussions are clearer, misunderstandings are minimised, and focused communication is ensured. At the same time, acoustic elements create optimal acoustic conditions for meetings, presentations and video conferences.

Yes. It is generally not a problem to retrofit acoustic elements into existing buildings. Depending on the room situation, wall-mounted absorbers, ceiling-mounted absorbers or free-standing acoustic elements can be installed, with no need for extensive construction work, ensuring the targeted improvement of room acoustics.

Yes. With appropriate planning, acoustic elements can be harmoniously integrated into existing room concepts. The huge range of colours, surface finishes, materials and formats means that acoustic elements can be individually customised to suit any architecture and existing design concept.

The choice of suitable acoustic elements depends on the room design, structural conditions and specific requirements. Factors such as room size, purpose, existing surfaces and the current sound level must be taken into consideration before a suitable acoustic solution can be determined.

Yes. Strähle supports customers with their acoustic planning and provides advice on suitable solutions for room acoustics and sound shielding, as well as on the implementation of individual acoustic requirements.
