In order for a room acoustic measure to be calculated and assessed realistically, well-founded acoustic physical basic knowledge and practical experience is appropriate. In particular, the initial values of reality must be determined accordingly. For sensitive areas, the measurement should be carried out professionally by an acoustic expert. Alternatively, at least a provisional measurement should be performed with a phone app repeatedly. The provisional measurement serves only as a guideline for the selection of the room materials and their absorption coefficients in the acoustic calculator. Basically, any calculation without professional measurements of the initial situation is hypothetical!

Example:

Low frequencies are absorbed differently than high frequencies. Glass surfaces (Windows) or a normal office cabinet made of chipboard in different thicknesses, when you hit the resonance of the deep tones, can act for the low frequencies absorbing. However, a correct calculation is hardly possible due to the lack of measured data of the objects. On the basis of a measurement, special depth absorbers (vibrating resonators) need to be specifically set.

The calculations are based on measured data from objects and materials. Some of these are listed in the DIN 18041 exemplary. Others are taken from various sources for their correctness and conformity with the actual existing object or material there is no guarantee.

• Area is important-small elements, for example, are simply overlooked by lower frequencies due to the long wavelength. Even with a-class absorbers, an adequately large absorbing surface is required in relation to the size of the room. In communication rooms, absorbers on the ceiling are sparingly and consciously dealt with. Here is more of a reflection desired!

Fragrant real hay, hay flowers and mosses applied directly to vitAcoustic absorber plates. Another versatile way of experiencing real natural products with all senses (seeing, touching, smelling). The special patented preservation and coating method opens up completely new design options. And the vitAcoustic natural-coated absorber plates can be used in all vitAcoustic applications, such as 3d frames, acoustic roller shutter cabinets, panel curtains for room division and flexible partitions and partitions. Made to measure: natural elements transparent or semi-transparent on colored vitAcoustic absorber plates. Design your individual acoustic nature picture with the 19 vitAcoustic colors and real hay, hay flowers and moss. You can choose between opaque and transparent. For projects, we also offer individual adjustments, eg semi-transparent. Very individual ideas can be implemented by coating the panels with various genuine natural materials such as hay, hay flowers and moss.

The first Kohlbecker building was called „The Human Factory“. Because Karl Kohlbecker wanted to ensure that a good quality of life does not end at the factory gates. That‘s a kind thought. And an entrepreneurial one: because when people feel comfortable, everything runs better. Quality increases, processes become faster, the work succeeds.

Workplace for people:

No compromises have been made in the equipment of each individual desk workstation. All components are individually adaptable to humans. Due to the special geometry of the desk, very advantageous workplace groupings result. The offset of the tables to each other is very pleasant. Direct counterparts are avoided. Instead, harmoniously spacious rooms are created between the desks.

A commitment to resource-saving sustainability:

1. Fast growing bamboo. Hard as solid oak. Now bamboo tops are the new green desktops for Kohlbecker employees.
2. All the decorative acoustic partitions are made of PET felt, which is made from recycled PET bottles.
