SOUND
Reverb: This is the word used to desribe the sound that you can hear in certain rooms or buildings for example in a staircase or in a church. you could describe a room as Reverberant instead of using a work like echoy.
A room that does not have much reverb is called dry or dead a room that could be this would be a room that has things that can absorb sound for example carpet hangings on the walls. reverberation happens when sound is reflected and you can hear lots of tiny echos that create the reverb sound.
Audio Recording studoes need ways to stop reverb apprearing on a recording to do this there are two ways one to use aucistic tileing this can be stuck onto a wall and the shapes of the tiles help to break up the sound the foam that they are made of can also help absorbe sound waves. The second way is to have sound proofing this is built into the walls and has different layers the totaally block any sound from going in or out. the Main difference is one blocks sound and the other stops reverb.
Anechoic Chamber- this is a room that has full aucoustic treatment and no sound at all get get in or out.
Pop filter- on the condenser microphones we use something called a pop filter whitch is like a circle of mesh that stops air from directly hitting the microphone when you are speaking this will make your audio recdoing better quality.
We went round to different locations in the college to see how reverbuant the different rooms were and made sound recordings using different mics and recorders. The recordings we make are attached below. While doing this task we found that the rooms / areas that had high ceilings and hard walls had the most reverb and the rooms that has softer walls for example the sound recording room that had the sound proofing on the walls there was less reverb because the sound was being absorbed by some on the things.
The sound recorders we used
Zoom h 1 N - we used this with a lavailleir microphone.
Zoom H4N - we Used this with a shotgun mic that was on a boom pole or on a handle.
