Definitions
- the object of the present invention is a system to eliminate noise of sound origin inside a receptacle, such as, for example, in the cabin of an airplane there is excessive noise due to the transmission of noise generated by the motors or by friction against the air.
- the present invention is characterized by the special design and configuration of each and every one of the elements that form part of the invention, as well as the functionality assigned to each of them so that, working together, they achieve a source noise suppression system. sound whose frequency is from a few hertz to more than twenty kilo-hertz, in a simple and efficient way.
- the present invention falls within the field of noise transmission suppression systems inside a receptacle.
- vibration-absorbing means are used, placed in the separation chamber defined between the receptacles, as in patent CN209467716U, or in other cases, positional stability between receptacles is achieved by means of springs. as it happens in patent CN209259375U.
- the object of the present invention is to develop a protective system for the transmission of sound inside a receptacle that has the above characteristics as described below and is included in its essentials in the first claim.
- the object of the present invention is a system for eliminating noise of sound origin inside a receptacle and comprising:
- a first receptacle or interior receptacle in whose interior it is sought to achieve the suppression of sound noise coming from the outside, where this first receptacle is a hermetic receptacle where the walls of this compartment must be sufficiently rigid and in a possible embodiment are used sheets based on honeycomb panel with light and resistant materials, or sheets based on resistant and heavy materials.
- Spacer means for the receptacles and maintainers of the separation chamber consisting of electromagnetic means in a facing arrangement, one on the outer face of the inner receptacle and the other on the inner face of the outer receptacle.
- the spacer means will be placed in such a way that an electromagnetic force can be created between each pair of them that repels them and prevents them from coming together due to inertia due to the movement of the receptacles or due to the collision of the elements that may be inside the first receptacle or interior receptacle.
- a first receptacle (1) or interior receptacle constituted by a cabin or room or enclosure, or closed space whose shape, without loss of generality, will be chosen as hexahedral or cubic.
- this first receptacle (1) has four vertical faces or walls, a horizontal face or base that we will call the floor and another upper horizontal face that we will call the ceiling. Regardless of the scale in which it is built, the validity remains constant as it does not depend on the size used. If it were big enough, we could call the receptacle a room.
- This first receptacle is airtight since it does not allow any fluid to pass through any of its faces, edges or vertices, be it liquid or gas, since it is the receptacle inside which the suppression of sound noise will take place. by preventing the passage of waves from the outside.
- the walls are resistant and light and in a possible embodiment they can be honeycomb walls with materials that allow sufficient rigidity to prevent the opposite faces of the different receptacles from coming into contact.
- first receptacle (1) or inner receptacle there is a second receptacle (2) or outer receptacle that may have a hexahedral or cubic shape and must be hermetic.
- the faces of both receptacles will generally be parallel as a first step to minimize the space or volume between them.
- the space between both receptacles, the first receptacle (1) and the second receptacle (2) defines a chamber (3) where the vacuum is going to be carried out, up to a level in which the sound transmission is very highly attenuated and therefore inaudible.
- the vacuum in the chamber (3) is carried out by means of an extraction system, a possible embodiment of which is a vacuum pump (5).
- the system has means for maintaining the separation (4) between receptacles based on electromagnetic means controlled from the outside and at will, said electromagnetic means being arranged opposite each other, so that a first electromagnetic means (or set of these ) (4.1) is arranged on the outer face of the first receptacle (1) and a second electromagnetic medium (or set of these) (4.2) is arranged on the inner face of the second receptacle (2) so that a magnetic repulsion is produced between both which ensures the dimensional stability of the vacuum chamber (3) and therefore, the separation between the first receptacle (1) and the second receptacle (2).
- Electromagnetic fields can be permanent or variable by passing a current through a set of loops or the like.
- the repulsion forces can be created with high value permanent magnets either by high force electromagnets or by high force permanent magnets combined with high force electromagnets.
- Said magnets must be faced two by two, either individually or in groups, to create points or rather zones of repulsion between both inner and outer receptacles with sufficient forces to compensate inertia and weight depending on the face or surface of the receptacles that are try.
- the system When the gases between the two receptacles are extracted with a suitable vacuum subsystem, the system thus composed will produce the desired effects and will allow the exclusion of sound waves, preventing them from passing from the outside to the inner receptacle.
- the system may also comprise one or more pressure sensors that allow the control and supervision of this magnitude in the receptacles of the patent, both in the inner receptacle and/or in the outer receptacle.
