Sound recording

What effects the acoustics of a room: The acoustics of a space begins with the size of the room. The length, width and even height of the room determine how sound bounces around the room. ... This is because sound passes through all elements, including solid materials, in a process known as sound absorption. 

Reverb: Reverb occurs when sound hits a hard surface and bounces off of that object and reflects back to the listener. This creates an echo which makes  you`re recordings not sound as nice and drowns out the sounds that you actually want to hear.

Dry rooms: A dead/dry room absorbs the sounds made so there would be less reverb.

In the image below of the stairs there would be lots of reverb because all of the sounds made have nothing to be absorbed by.

The image on the left would be a dead/dry room because the sound would be absorbed and there would be less reverb than there would be on the stairs.

When using the sound recorders you can use lots of combinations to record your audio. When using the H4N sound recorder you can plug in a Rifle/Boom mic for better audio recording in different environments. you can also plug in a conventional hand held microphone and this could be used in interviews.

When using the H1N sound recorder you can use the lavalier. with this microphone you can clip it on to a subjects clothes this i a discrete audio recording device that is hidden from the camera. Using this combination is good for interviews.
