Comfort and quality factors
Many people are not aware that in most interiors action with regard to the room acoustics is needed. Indeed, room acoustics is important in the planning – and not only in halls or classrooms, but everywhere, even in the private dwelling environment. Quiet and good speech intelligibility increase the practical value of the room – quite apart from the positive health effect of noise reduction. In buildings made of LIGNO®, acoustic quality can be taken into account from the start.
In planning new buildings consider interior design and room acoustics together
Lignotrend integrates the room acoustics function where possible directly in the load-bearing construction parts for ceiling and roof. This way, unlike conventional construction, planners solve statics, design and room acoustics in one component - right from the start. Since this includes the final real wood acoustic surface and subsequent overhead interior fittings work is not required, there is a direct cost benefit compared to conventional suspended systems.
Additive solution in real wood
It’s not always load-bearing constructions: to deal with room acoustics by means of cladding, Lignotrend can supply large-size real wood panels with the same appearance. The light sound-absorbent LIGNO® Acoustic light panels improve the sound-reflective surfaces of masonry and concrete, and non-absorbent wood surfaces – biologically faultless, also in renovation. If a very flexible cable routing is required, the cladding can be applied using the usual suspension systems.
Good room acoustics in harmony with the design
Timber, profile and absorber variants
Regular slat profiles
With LIGNO® Acoustic light acoustic profiles, with regular slats, a restful surface appearance can be obtained. Various slat-joint combinations are available.
Non-regular nature-slat profiles
The different slat widths of the LIGNO® Acoustic nature profile let surfaces seem to have grown organically and so look very natural. It is available in different variants (joint width 4 or 6 mm).
3D slat profile
The three-dimensional profile LIGNO® Acoustic nature:3D provides a further, dynamic design option. The variant with graduated height slats of fir or oak has the Focus Open design award. As an appearance with design protection, it is available only from Lignotrend.
Board strip profiles
Strip profiles are the classics among the Lignotrend acoustic profiles. The various designs are used only for the load-bearing glued laminated timber element.
Types of timber
Lignotrend visible surfaces in many high-quality types of timber further extend the use and the range of aesthetic interior architecture – from light elegant silver fir to rugged oak, in some cases with the option of a surface treatment.
Lignotrend uses natural wood fibres as sound absorber, to ensure efficient performance. Various tested structures reach absorption coefficients aW of up to 0.90 – distributed over a wide band of the relevant frequency spectrum.
Profile with low absorbency
If partial areas of a component are to be made with low absorbency, panels without activated absorbers can be used. The appearance is that of the absorbent profiles.
The difference sounds like this: Calculate acoustics and make audible
Lignotrend room acoustics calculator
With the Lignotrend room acoustics calculator, reverberation and noise-level reduction can be calculated and adjusted for the requirements of DIN 18041 – acoustic quality in rooms. Planners and building owners can use the online tool for indicative calculations for the necessary absorbent surfaces of Lignotrend products. This distinguishes between the room groups from DIN.
NEW: A “before-after feature” makes the difference between the room acoustic situation with and without measures audible as a (qualitative) auralisation.
Note: The calculation software determines the absorber area required for the described cubature but gives no indication yet of its layout in the room. Therefore, the results do not replace the assessment of the building project by an acoustics specialist.
