Something Useful

it's better for me to write something useful. I planned to write something bout So called "Brother Louis XVI", and his lame ass girlfriend named "Maria Antoinette".

Let's talk about Reflection and Reverberation (Since next week is my Acoustic assessment)

Here We Go....

*Reflection is Sound Waves that hit a hard surface then giving rise to reflections and it will reflects

*Reflection become regular and orderly if Sound Waves hit smooth surface, It'll become irregular when hit rough surface

*Law of reflection says....

 "Angle of Incidence Equal Angle Of Reflection"

*Reflection is always weaker than original sound, it's because of the surface absorb some energy from Sound Waves, and can be called also as loss of energy

*Loss of Energy is because of "Conversion into heat by Friction" is called "Absorption" 

*There Is No Reversal of Phase when Reflection happened

*(Need A Revision) Sound Intensity is enhanced because the reflected waves, adds to the incident waves, giving pressure to amplitude twice in a "Pressure Zone" near the surface

*One of the application can be used in Reflection is, Pressure Zone for microphone

It helps the microphone to increase the sensitivity giving double pressure to 6dB so it become louder.

(Question Your Friend bout Pressure Zone and Weaker Reflected)

Reverberation is results of reflections

*Collection of Reflections results in Reverberation

*Reverberation is used to overcome Inverse Square law

(Which's Say)

"Intensity Of Sound Drop Quarter or Approximately 6dB in Every Doubling of Distance from the Sound Source"

Usually, it applies on an open air live concert

*Reverberation Time / RT60 defined by time for sound to drop about 60dB after the source sound stop

0 (Zero) is for perfect reflection, 1 is for perfect asborber
