Sound reflection, absorption and diffusion – Definition and treatment

By Acoustics, Architecture, Construction, Decoration, News No Comments
Sound reflection, sound absorption and sound diffusion are three sound behaviours that should be taken into account when undertaking the acoustic conditioning of a space. The final quality of a constructive space is determined by multiple factors, including the acoustic aspect which is very relevant. A negative enveloping acoustic atmosphere causes communication difficulties, stress, lack of concentration and fatigue. If one does not take care of acoustics, one fails as an architect or decorator in creating comfortable environments for living, working or carrying out other tasks. Let's define these three sound behaviours. When a sound wave encounters a material obstacle that opposes its propagation, three things occur: A part of the energy is reflected. That is what we call sound reflection. Architectural acoustics addresses this phenomenon with the use of non-porous materials, rigid materials and smooth materials. Another part of the energy is absorbed and continues its propagation through the material that is hindering it, giving rise to what is known as sound absorption. When treating sound absorption, porous materials, resonators, furniture and people are taken into account. In particular Spigogroup acoustic panels, which are made of natural wood, show excellent properties of acoustic absorption. The last part of the energy is transmitted producing the third phenomenon that you need to anticipate: sound diffusion, that is, the, preferably uniform, dispersion of sound in different directions within a space. Thus, to ensure that sound waves reach spectators equally from anywhere, creating a surrounding sound that increases the acoustic quality of an enclosure, ceiling elements, accordion walls, sound diffusers and sound diffractors are .

Wood ceilings for museums: the Hall of Mayors of Bilbao City Hall

By Acoustics, Architecture, Construction, Decoration, News, Spigogroup wood projects No Comments
Wood ceilings for museums are unique projects, as much as the buildings that feature them and the works they cover. A wood ceiling designed for an exhibition hall should make a contribution to the decoration of the room while leaving the leading role to the artworks on exhibit. This project is a clear example of this. The Hall of Mayors of Bilbao City Hall is a 100 m² space located in the west wing of the building. It holds about twenty portraits of most of the mayors of the city, from 1873 until today. The room offers visitors a restful atmosphere, with dim lights, which invite one to contemplate the paintings that stand out in this environment for their own lighting. It was necessary to install a solution on the ceiling that would provide order and harmony, integrating downlights, speakers and other elements, but also respecting the sobriety and elegance of the room. A Spigoline wood slat ceiling was chosen. It is comprised of wood slat panels laid out in a GRID system, model 5-15-70-55, with solid obeche wood finish, stained with standard varnish, installed with fastening fastening clips. The result is extraordinary, achieving a perfect aesthetic solution that also gives the room a feeling of greater breadth.

Five interior wood ceilings that you will want to include in your projects

By Acoustics, Architecture, Construction, Decoration, Inspiration, News No Comments
There are many types of interior wood ceilings. In some cases wood slats are used and, on other occasions, smooth wood tiles. Some opt for covering ceilings with sound-absorbent acoustic panels forming the so-called acoustic ceilings. Sometimes they even choose design ceilings with stepped and curved surfaces. Seeing some of the best interior design and decoration projects that have employed wood ceilings, it is clear that wood is the favourite choice of those who want to offer a modern, elegant, cosy atmosphere. Here are some examples of interior wood ceilings which you will probably wish to include in your next projects.   Lucena Renewable Energy Centre A very special project in the town of Lucena, Cordoba, where we used decorative false ceilings of the Spigotec brand Liso and Aries 25 models with beech veneer.       Nuestra Señora del Pino student residence Spectacular interior wood ceiling made with wood slat panels finished in white. (white lacquer finish and B-s2, d0 fire proofing). Spigoline Grid System wood slats (model 5-15-70-55) were supplied for ceilings, and installed on a primary structure consisting of T-15 rods. Locking clips were used to join the grid to the rods.       Fundación Laboral de la Construcción The new headquarters of La Rioja Building Labour Foundation features an extraordinary curved wall-and-ceiling featuring Spigoacustic brand model 28-16-16 AS wood cladding in natural varnished cherry veneered wood.       Dinastía Vivanco Museum of the Culture of Wine Acoustic conditioning of the museum audiovisual room by covering floors, ceilings and walls forming three overlapping Spigotec type wood boxes made of acoustic panels of sound-absorbent wood finished in balsamic walnut, ash and alder.       San Nicolás Culinary Club The dining room of this foodie club has a welcoming acoustic interior wood ceiling made of Spigoline model 6-30-35-30 wood slat panels, with a solid obeche wood tinted finish, offering a remarkable acoustic improvement and a warm and modern look.   .

This is how 2020 starts at Spigogroup

By Acoustics, Architecture, Construction, Decoration, News No Comments
We have already returned to start the new year. 2020, the year in which, we are sure, wood designs will succeed, as in previous years. With relaxed bodies, minds and spirits, and a smile on our faces after these days of rest, we have re-lit the signs on our façade. We have also restarted the machines that will be working away during the next 365 days, manufacturing acoustic panels, inner linings and wood slats to be used in the new projects that will opt for a wood-based design in 2020. The screens, no longer dark, are once again displaying technical assembly and cutaway drawings, quotes and calendars, that are gradually filled in with the tasks to be completed. The phones are ringing again and, on the other side, voices consult us in different languages about technical data and deliveries or announce that we have successfully completed a new project. Our Optimum Reverberation Time Online Calculator will continue to offer acoustic reports to those who are going to undertake the acoustic conditioning of a room. Our Quote Request Online Tool will continue to send requests to our mailboxes. And lorries will reappear at the docks of our warehouses in search of technical doors, wood ceilings, sports furniture and acoustic tiles to be delivered to sites across the country and beyond. Yes, we have returned, and now, we will let you get back to work.     If you liked this post about wood designs, you may also be interested in: - Interior wood ceilings in the work of Kengo Kuma - The 3 possible contributions of decorative acoustic panels for the aesthetics of a project - Colour acoustic panels for decorative projects in shops - 5 Reasons why you should use obeche wood slats in your project
