Acoustics


 * DEFINITIONS **

Speed: Distance travelled in unit time --- m/s



Frequency: Number of complete cycles in one second --- Hz



Wavelength: Distance between matching points on the wave --- m



Longitudinal: Vibration parallel to direction of travel of wave. (the first image in the picture)

Transverse: Vibration at right angle to direction of travel of wave. (the second one)



From videos

The sound is not only produced by music instruments in fact we can say that the sound they produced is not something musical but the combination of diferent sounds creates a melody. The sound is produced by the vibration of the objects, at the same time this vibration create waves in the air and this wave make some distorsion that causes the sounds.

The molecules of the air move back and foward with this vibration and the number of moves they make is a second is what we call the frecuency of the wave. The size of the wave is call amplitud and the long is the amplitud the louder is the sound.


 * All about Sound

Room acoustics are about the way in which sound behaves in a room. Sound transmission, sound absorption, sound reflection and sound diffusion are all aspects that are important here. Room acoustics also include how we as humans perceive different acoustic phenomena.

room to room insulation

vertical airborne sound insulation

one way sound insulation

impact sound insulation

Also is too important that the architect learn about the design of a suitable acoustic room and all of types that there are.
