One of the most efficient, cost effective and widely used approaches to reduce the tonal signature of aeronautic engine noise is the so-called liners-structures located in the internal walls of the nacelle (the external structure of the motor) that form an acoustic treatment. In the research project called "Silent Aircraft", funded by FINEP and Embraer S.A. and involving some Brazilian universities, including the Federal University of Santa Catarina (UFSC), an extensive study has been conducted to better understand the behavior of such elements, as well as to predict its effect on engine noise.
The flat rubber type is used in a door that doesn't fit well, rubber and metal gaskets work on doors that are pretty tight already. The brush material is for sliding surfaces. Don't forget the bottom of the door-- the best gaskets are spring loaded and drop down when the door is closed.

What I've said so far might seem to imply you can take care of all acoustic problems by making every surface absorptive, completely deadening the room. Actually, such a room is rather unpleasant to work in, but even if it weren't, any attempt to create it would probably be a disaster. The problem is that all absorptive materials are frequency selective. As a general rule, high frequency sound is absorbed more readily than low, so as absorption is added to a room, the reverberation becomes more and more bassy in tone.
Ao passo que a STC utiliza apenas um número de modo a todo este espectro do frequência, qual geralmente Pode vir a ser ilusório em termos do performance real.
Se cobogo você precisa por várias referências para entender a diferença entre uma acústica óptima e ruim, realize o teste DE palmas em uma ampla variedade por ambientes variados, e perceba quais MODELOS tendem a soar melhor.

The design is reminiscent of the iconic Cobogo bricks. Frizzo utilizes an innovative water jet cut leather hand woven pattern that brings a palpable relief and texture to each chair. The Cobogo chair is an homage to Brazilian innovation and creativity which transforms social, economical and environmental issues to practical and intelligent design solutions.

These steps can result in a very quiet space, here but they get progressively more expensive-- the real question is when is it quiet enough? The easy test is to make a recording of the space.
Footsteps can cause similar effects to a somewhat lesser extent. click here This is usually not severe with wood frame construction but can be a nightmare in a concrete and steel building.
