Acoustics

=Speed: distance traveled in unit time (m/s)= = = =Frequency: number of complete waves in one second (Hz)= = = =Wavelength: distance between matching points on the wave (m)= = = =Longitudinal: vibration parallel to direction of travel= = = =Transverse: vibration at right angle to direction of travel= = = =Sound: is how we perceive the pressure changes in the air when something vibrates at a certain speed. When this waves encounter a solid object they:= = = = = =Sound Insulators: also known as acoustic insulation, any means of reducing the intensity of sound= = = =Reverberation: The time it takes for the sound pressure level to fall by 60 dB after the sound has been turned off. Measuring the reverberation time allows us to calculate the total sound absorption. The reverberation time varies according to the frequency.= = = =When you are in a building process it is essential that you specify your room acoustics requirement so it’s ensured the optimal sound elimination or amplification according to the future use of the area.= = = =There are easy and cheap ways to make any room of your home quiet and calm with the correct use of carpets, furniture, whether stripes and insulating materials like cardboard.=
 * =Transmit: it passes with a lower volume through thin objects.=
 * =Absorb: the sound doesn't passes through, it’s absorbed by soft objects that reduces or eliminates the vibration of the sound wave.=
 * =Reflect: it bounces of the object in the same direction but in opposite way.=
 * =Diffuse: the wave touches a non smooth surface, parting and bouncing in every direction.=
