Sitting alongside a material palette of sisal fibre, concrete and plywood, the humble cobogó brick – a staple of Brazilian architecture – takes centre stage in the Campana’s design
Boeing funded model and full scale ground tests were performed to provide insight and technical background relating to acoustic and propulsion performance of plug nozzles. The information thus obtained was used in the design of the full scale hardware. Full scale engine ground tests were performed on two configuration of the Phase 2 upper goal quiet nacelle to determine its acoustic and propulsion performance and to permit comparison with the performance of the Phase 1 nacelle.
a diverse digital database that acts as a valuable guide in gaining insight and information about a product directly from the manufacturer, and serves as a rich reference point in developing a project or scheme.
Arktura architectural ceilings are an acoustical drop ceiling systems based on a grid-layout configuration. TriSoft® ceiling system is an easy way to add faceted dimensionality and elegance to get more info interiors.
There are three things that can happen when sound hits a wall. It can be reflected, absorbed, or diffused. If the wall is flat and hard, the sound will get more info be reflected. A single strong reflection can sometimes be heard as an echo, but in most rooms a lot of reflections (including reflections of reflections) combine into the reverberation.
The soft volumetric geometry of the hollowed-out elements comprising the walls is a complex construction, made with infinite curved lines. The modular element, a work of art, was designed by the Austrian-American Erwin Hauer who, since 1950, has conceived and made sculptures for architectural space. His minimalist elements dialogue more info with the architecture and remind us of some traces of Brazilian modern architecture.
One of the most efï¬cient, cost effective and widely used approaches to reduce the tonal signature of
(In larger rooms even more reverb is desirable because it read more helps fill the hall with sound.) For listening to speech or music played through loudspeakers this amount of reverb is too much-- values around a second are more comfortable, and for critical listening to speakers the RT60 should be close to a half second.
Electrical fittings are another source of leakage. Take the plates off light switches and receptacles, fill the gaps between the box and the gypboard, and add a sealing gasket when you put the plate back on.

No espaço livre, a intensidade por vigor da onda diminui na medida em de que ela se afasta da fonte sonora.
The depth of a diffuser determines the lowest frequency that will be affected. A diffuser one foot deep will scatter sound down to 160 hz.
