‘We developed a special floor made of cobogó brick filled with concrete; a fully experimental work that resulted in a beautiful pattern,’ explains Humberto. ‘We employed sisal fiber as a natural background that complements the strong graphic effect created by the cobogó brick.

A mathematical procedure is developed for calculating the parameters of a singlelayer perforated-plate acoustic liner in order to achieve a specified acoustic resistance and reactance for single-frequency excitation. The method includes the standard impedance terms, due to viscosity, radiation, and backing effects, and also the terms due to high sound amplitude and steady tangential airflow. Emphasis in the analysis is on these latter non-linear effects. Specification of acoustic resistance and reactance (at one frequency and set of environmental conditions) means that two quantities are used to determine the four liner parameters: fractional open area of plate (porosity of plate), thickness of plate, diameter of hole perforations, and depth of backing cells.
Double and triple walls, isolated concrete slabs, custom steel doors are all standard but high priced items used in their construction. A studio's sound is its number one asset and most owners will go to any lengths to get it right.
(there is only one fist prize, and designboom usually asks renown professionals to help check here us to promote talent.
The brickwork extends through the internal courtyard, including a specially developed floor of cobogó bricks filled with concrete
The aspect of reverberation you hear about the most is reverberation here time. This is the amount of time it takes a loud short sound to die away. "Dying away" can be defined more scientifically as a drop in loudness of 60 dB, so acousticians call reverberation time RT60.
The effect is multiplied throughout the ambient, making a construction from the light itself. Throughout the days, throughout the months, the hollowed-out elements take on different forms with the incidence of the sun; at night, this effect once again is transformed; in a continuous process of metamorphosis, its form changes from more info the light.
Este nosso projeto por quarto foca na simplicidade e deixa em destaque a fotografia do casal, que pode ser substituÃda por ilustrações ou obras de Feição do sua própria preferência. O mesmo conceito Têm a possibilidade de ser aplicado de modo a outros objetos.
The curtain over the window Is too light to be a really broadband more info absorber, but it combines with the low frequency absorption of the glass to give a reasonably flat overall effect. The carpet and wooden floor interact in much the same way.
This kind of noise must be treated at the source. Walking areas should be carpeted, and heavy appliances have to be mounted with shock absorbers or placed on thick rubber pads. In a wooden house sound tends to be transmitted along the floor joists, so some problems can be solved by simply moving the offending machines.
Near field monitors should not get more info be against a wall, but most large systems depend on a wall backing for extended bass response. The speakers were hung about seis ft from the floor. This is a bit on the high side, but was necessary to allow the placement of a writing table underneath them.
