Acoustics

= Acoustics =

__// Sound //__
The sound is a result of vibrations, and comes in the form of kinetic energy.

All objects produce different sounds: __

Large objects__ produce Big Waves and low pitch. __Small objects__ produced Small Waves and high pitch.

Speed is measured by how many metres the wave travels in one second. Frequency is the number of times the waveform passes a point per second. Wavelength is the distance between matching points on a wave.

Speed = Frequency X Wavelength
Longitudinal: the direction of oscillatory movement of the wave equals the propagation direction Tranverse: A wave in which the disturbance is perpendicular to the direction of propagation is called a transverse wave.

The architecture is directly related to the acoustics, how people can perceive and feel the space is taken over by the noise, the sounds play an important role in the atmosphere. To classify a room like noisy or not depends on the use that is assigned to the room, not the same a quiet reading room, a restaurant full of people chatting in a subdued tone. .

Excessive noise not only creates discomfort, but also health problems such as stress, fatigue, anger, etc..
