Definitions

  • the invention relates to the field of false walls, and in particular that of false ceilings and false walls.
  • the invention relates more particularly to an acoustic absorption assembly intended to be placed in a room with a view to controlling the acoustic behavior of the latter.
  • the sound absorption assembly is intended in particular, but not exclusively, to be associated with a false wall formed inside a room.
  • the false walls are made from frames suitable for being fixed to a wall or a ceiling of a room and from flexible sheets stretched over these frames.
  • false walls made with stretched flexible sheets have a major drawback which is that they exhibit poor acoustic properties.
  • the taut layers indeed reflect the sound waves, thus generating a significant phenomenon of reverberation (or echo) of the sound waves.
  • acoustic absorption assemblies comprising flexible sheets provided with micro-perforations in order to make it possible to increase the absorption of sound and therefore to attenuate the reflection of the sound. sound waves.
  • WO200807737 which describes an acoustic absorbent assembly comprising two stretched sheets provided with micro-perforations extending substantially parallel to the wall to be covered.
  • US2013148357A1 also describes an acoustic absorption assembly comprising a tubular body closed at its two ends by flexible micro-perforated layers.
  • the acoustic absorption assemblies of the prior art have several drawbacks.
  • the acoustic assemblies of the prior art are efficient essentially for the absorption of sounds at frequencies above 1500 Hz (high frequencies).
  • they remain inefficient for the absorption of sound at low frequency (frequencies below 300 Hz).
  • the acoustic assemblies of the prior art are fixed directly to the wall to be covered.
  • the absorption zones therefore remain limited to the number of micro-perforated sheets.
  • the invention aims to remedy these problems by proposing an acoustic absorption assembly offering satisfactory acoustic properties at both high and low frequencies while offering an increased absorption capacity with regard to the acoustic absorption assemblies of the system. prior art.
  • the invention also aims to provide an acoustic absorption assembly making it possible to illuminate the room in which it is placed and / or to offer an aesthetic rendering while ensuring the acoustic insulation of the latter.
  • the invention provides an acoustic absorption assembly according to claim 1.
  • the sound absorption assembly allows sound absorption at high and low frequencies and offers a larger sound absorption zone than that offered by the sound absorption assemblies of the prior art.
  • low frequencies frequencies below 300 Hz and by high frequencies is meant frequencies above 1500 Hz.
  • micro-perforations is also understood to mean perforations having a diameter of less than 5 millimeters.
  • the diaphragm is fixed to the body by means of vibration damping means. This makes it possible to prevent the vibrations to which the diaphragm is subjected are damped by the damping means, thus preventing the acoustic assembly from being subjected to vibrations.
  • the sound absorption assembly comprises at least one stretched internal flexible sheet interposed between at least one of the micro-perforated flexible sheets and the diaphragm.
  • the internal flexible sheet may be either micro-perforated or devoid of perforation.
  • the sound absorption assembly comprises at least one panel of absorbent porous material (s) interposed between at least one of the flexible plies (end plies or internal ply (s)) and the diaphragm.
  • the sound absorption assembly comprises light means provided in one of the spaces.
  • the diaphragm is a flexible metal plate.
  • the metal plate is arranged parallel with the flexible plies (end plies and internal ply (s)).
  • At least one of the flexible plies is translucent.
  • the sound absorption assembly is advantageously intended to be mounted on a false wall.
  • the invention also relates to an installation according to claim 11 comprising a false wall and at least one sound absorption assembly as described above.
  • said assembly is fixed to the false wall at a distance greater than or equal to a limit value. More particularly, it is a question of placing the acoustic assembly so as to have one of the micro-perforated flexible sheets at a distance greater than or equal to the limit value
  • the acoustic assembly thus offers a double entry sound waves, increasing the wave absorption surface and thus improving the sound insulation of the room in which the system is located.
  • the limit value is of the order of 2 centimeters.
  • an acoustic absorption assembly 1 according to a first embodiment, said assembly being shown mounted on a false ceiling 50.
  • the fixing means of the assembly of sound absorption on the false ceiling have not been shown. They can include any suitable means known to those skilled in the art such as for example lines or more elaborate systems such as those described in the patent application. FR2867797 .

  • the box body 2 is of parallelepiped shape. It is understood that the box body 2 is not limited to this shape, the latter being able to take any other shape without departing from the scope of the invention.
  • the ends of the box body 2 are advantageously provided with fixing means conventionally used for fixing tensioned plies.
  • the sound absorption assembly 1 also includes a flat diaphragm 5 absorbing low frequency sound.
  • the diaphragm is a flexible metal plate. This is arranged inside the tubular body 2, between the end plies so as to delimit between said plies two preferably distinct spaces 6, 7. In other words, the spaces 6, 7 do not communicate with each other.
  • the metal plate 5 is arranged parallel to the end plies 3, 4.
  • the metal plate 5 is fixed to the box body 2 by means of a fixing system provided with vibration damping means (not shown).
  • the damping means consist of one or more parts made of a flexible material so as to allow the absorption of vibrations between the metal plate 5 when the latter vibrates under the action of acoustic waves and the body 2 box supporting said plate.
  • the metal plate 5 can thus vibrate and absorb the low frequencies without the acoustic assembly 1 also vibrating.
  • the damping means are Silent Blocks®.
  • the metal plate 5 is advantageously located at an equal distance from the end plies 3, 4.
  • the acoustic assembly 1 is mounted so as to have one of the end plies 3, 4 facing the false ceiling 50, the box body 2 extending substantially perpendicular to the plane of the false ceiling 50
  • the acoustic assembly 1 is placed at a certain distance from the false ceiling 50 so as to double the acoustically treated surfaces. Indeed, by being placed at a certain distance from the false ceiling 50, the acoustic assembly 1 offers a high surface (corresponding to the end sheet 3) and a low surface (corresponding to the end sheet 4) micro-perforated. absorbing high frequency sound.
