Acoustics


 * SPEED:** Rapidity in moving, going, traveling, proceeding, or performing; swiftness; celerity: the speed of light; the speed of sound.
 * FREQUENCY: ** Frequency is the number of occurrences of a repeating event per unit time. It is also referred to as temporal frequency. The period is the duration of one cycle in a repeating event, so the period is the reciprocal of the frequency.
 * FREQUENCY: ** Frequency is the number of occurrences of a repeating event per unit time. It is also referred to as temporal frequency. The period is the duration of one cycle in a repeating event, so the period is the reciprocal of the frequency.


 * WAVELENGTH: ** The distance, measured in the direction ofpropagation of a wave, between two successive points in thewave that are characterized by the same phase ofoscillation.


 * LONGITUDINAL: ** Extending in the direction of the length of a thing; runninglengthwise: a thin, longitudinal stripe.


 * TRANSVERSE: **Lying or extending across or in a cross direction; cross.

I learned that large objects make big wavelengths and create waves with lower pitch or frequency, otherwise small objects creates more wavelengths but then create higher pitch or frequency than large objects.

Impulsive sources concern exhilaration noise, for example when we clap our hands, because there is a force between our hands, but if we clap our hands in different ways then we got different noises

Sonic Booms happen when the waves bunch together and eventually form a shortwave which is the sonic boom of the explosion of a balloon, resulting the speediest sound. When someone crack a whip, he start for making a shape in the whip, and the top of the whip accelerate to 2 or 3 times for a speed of sound, otherwise the rest of the whip accelerate 10 times for a speed of sound.

Some architects visited Galicia in Spain. This city contains a lot of culture in architecture. The purpose of the structures built in this city is to make the buildings as easy in the ears as they are in the eyes. The walls of the building create spaces against the bounce of sounds, because there is a problem of high reverberation time. The objective is kill the sound using all kind of instruments to achieve it.
