Acoustics



** Architectural Acoustics ** // is conceived as the science of controlling sound within buildings. // // first application>> design of // opera houses // and // concert halls //. //



Elevated noise levels create stress, increase workplace accident rates, and stimulate aggression and other anti-social behaviors. ** The Importance of Acoustics in Restaurants **

-The appetite goes with the experience of the ambient. No one would like to eat in a restaurant too quiet or too noisy.- -It would be ideal to build restaurants with materials which absorb ambient noises. -It's important to break down the different noises that will be involved with restaurant design (background music, kitchen noises, the noise restaurant generated by consumers itself and other elements like residential sector noises, educational and offices sounds)  -There some acoustics treatments which can be achieved cost effectively like suspended ceilings (giving them the trend of the moment) and [|Fabric Wrapped Acoustical Wall Panels]. -It's important to pre-plan the operational sound issues. When you want to mix different ambients like an open bar and a restaurant you have to consider factors such as the noise quantity of each space. -The noise-cancelling technology should be wisely implemented because it's expensive and sometimes unnecesary.

**SOUND**

is a kinetic energy form caused by vibrations. It transport by the air as sound waves through pressure changes.

rarefaction= //decompression// "Pitch" is called frecuency too. the higher frecuency that the human ear can hear is 20.000 Hz (Hertz) and the lower 20 Hz.

**Speed: ** distance travelled per unit time. The speed of sound at Physics is the speed at which sound wavestravel through a medium.
