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 Emb

"A lie is a lie/This god is an eagle/Or a condor for war and nothing more," he yells before DJ Shadow showcases his turntablist expertise on the outro. Just a year prior, the duo worked together on Shadow's "Disavowed," a B side on which De La Rocha played the drums and is also credited with co-production.Estende-se a manta sobre a conduta

Accoustical System Modules are built from our Soft Sound® acoustical material, which can provide an NRC rating of up to .90. Couple that with the system's angular faces and modularity to achieve amazing acoustical performance across an entire space or simply over a desired zone.The trio of engineers named these bricks, “Cobogó”, f

Creio qual você já teve problemas em tomar uma mixagem em sua sala, e quando vai escutar em outro local o som soa diferente.The only way to get an objective measurement of sound levels is to use an SPL meter. (There are some inexpensive models by Gold Line/loft or Radio Shack.) As measured by the "C" scale on these meters you will find the fo
