Definitions

• the invention relates to a cabinet furniture with a furniture body and at least one front blind, which has parallel to each other arranged connectable profile elements and which is guided in arranged on the furniture body guide grooves.
• Such cabinet furniture are already known from the prior art. There are described profile elements which are articulated to form a shutter with each adjacent profile elements and which are for opening or closing of cabinet furniture. These existing from profile elements arranged in cabinet furniture shutters from the prior art cause when opening and closing due to the material itself noises.
• DE 103 43 956 discloses a cabinet furniture, with a furniture body and a front blind, the parallel arranged profile elements, here called lamellae, and is guided in arranged on the end faces in the walls of the furniture body guide grooves.
• This cabinet furniture should be designed so that the blind can have comparatively high profile elements. This is to be achieved by the fact that the profile elements are connected at their front sides with linking members which have on their sides facing the center of the front blinds connecting areas with the profile elements and respectively on the outwardly facing to the walls sides in the guide grooves engaging pivot pin over Pivoting eyelets are connected to the respective adjacent linking member.
• a disadvantage of this cabinet furniture is seen that a sound-enhancing effect is achieved by the geometry and the material used of the profile elements of the front blind, since the resulting in example. Office space sound is reflected back over a large area again.
• the invention is therefore based on the object to improve the known disadvantages of the prior art and show cabinet furniture that can be produced economically and inexpensively and are particularly improved in terms of sound-absorbing properties.
• the cabinet furniture according to the invention is characterized in that the profile element has at least one flat profile body into which at least one opening is made.
• This solution is simple and has the advantage that the sound can penetrate through the opening in the profile body of the profile element in the cabinet furniture and spread there.
• the sound is at least partially absorbed in the cupboard furniture.
• the sound reflected back from the cupboard furniture is now at least partly reflected back into the cupboard furniture by the profile elements of the front blind, so that only a very small part of the sound is reflected back into the room.
• the width of the opening is less than half the width of the front wall of the profile body of the profile element, preferably less than a third. It has been found in investigations that inexpensive furniture with front blinds can be produced with these specifications, with good sound absorption effect. Also advantageous has been found that a size of the surface of all openings of the profile body of the profile element of less than 45% or more than 3% of the surface of the front of the profile body of the profile element leads to dimensionally stable profile elements or front blinds, which depending on the size of have generating surface optimized Schallabsorbtions für
• the center distance of the openings is greater than or equal to the extent of the opening in the longitudinal direction of the profile body of the profile element.

• the soundproofing element can be formed by a membrane, for example made of plastic. With such a membrane, material-specifically targeted desired sound frequencies can be influenced or absorbed.
• the soundproofing element extends over the entire length of the profile element, which leads to inexpensive cabinet furniture with optimized Schallabsorbtions Signen.
• the profile body and or the profile element is formed so that it has fastening devices for fastening the soundproofing element, so that a cost-effective production of such profile elements with optimized Schallabsorbti- ons Koch is possible, which can prevent accidental displacement or slippage of the soundproofing element.
• the soundproofing element is connected over its entire surface to the profile body of the profile element, which enables cost-effective optimized production, for example, in the coextrusion process known per se.
• the cabinet furniture according to the invention with the consisting of the profile elements front blind has a sound absorption coefficient according to EN ISO 354 of at least 0.4.
• the sound absorption coefficient represents the ratio of the equivalent sound absorption surface of a test object to the surface of the test object.
• the surface of the test object in this case the cabinet furniture according to the invention, is the surface of the floor or the wall which is covered by it.
• the equivalent sound absorption area of the test object is determined from the difference between the equivalent sound absorption area of the reverberation room (the office room) with and without the test object (cabinet furniture).
• the equivalent sound absorption area of a room is defined as the hypothetical size of a fully absorbing surface without diffraction effects, which would give the same reverberation time in a room as if it were the only absorbing element in space.
