Acoustic panels
What do acoustic panels do and why do they improve room acoustics?
Acoustic panels are specially designed elements for improving room acoustics. They are made of sound-absorbing materials such as acoustic foam or non-woven fabrics and are specifically installed on walls or ceilings to reduce disturbing noises.
Acoustic sheets
What types of acoustic sheets are available – and which ones are particularly effective?
Types of acoustic sheets:
Acoustic foam sheets
Ideal for reducing reverberation and improving speech intelligibility. Particularly effective in offices, studios and classrooms.
Polyester non-woven sheets
Sustainable, lightweight and flame-retardant. Suitable for public institutions such as schools and nurseries.
Designer acoustic sheets
Combine sound insulation with aesthetic appeal. Available in various colours and shapes.
Basotect® sheets (melamine resin)
Highly effective at medium and high frequencies. Particularly popular in music rooms and technical areas.
Acoustic elements
How do acoustic elements contribute to interior design and atmosphere?
Acoustic elements such as wall panels, ceiling absorbers, seating cubes, door insulation and room dividers not only improve the sound quality of a room – they are also a design tool that creates atmosphere and structures spaces.

Sound insulation
Sound insulation is the acoustic shielding of a room or device in order to prevent or reduce the transmission of air-borne or solid-borne sound to neighboring spaces. The aim is to prevent the sound from propagating by using sound insulation materials to build a sound barrier around the noise source.
Threshold of pain
The threshold of pain (or: pain threshold) is the sound pressure level above which people perceive a sound event as being painful. For most people, the acoustic threshold of pain lies between 120 dB and 140 dB.
Solid-borne sound attenuation/damping
Solid-borne sound attenuation is the absorption of solid-borne noise by a layer of suitable material, e.g. heavy foil, on the parts/elements where the solid-borne sound propagates. Solid-borne sound attenuation prevents the conversion of solid-borne sound into air-borne sound. For this purpose, the medium’s surface is covered with a homogeneous layer of acoustic material (adhesive fixation or other) that transforms sound energy into other energy forms.
