You can cancel background noise when doing Foley recordings in your project or home studio, or have a portable mini dead room, ideal for specialized field recording.
The DIY Portable Mini Vocal Booth is ideal for podcasters, DIY filmakers and sound designers alike. My personal motivation to build this, was a desire to have a mobile mini deadroom to make foley recordings and recordings for my music.

Step 1: Why a Mini Vocal Booth?
In Short: If you dont have a treated room your audio quality gets comprimised by the reflections of soundwaves on hard surfaces in your room. A deadroom or treated room, ensure a clean recording with as little 'room' or 'echo' as possible. Once you have the perfect recording you can treat the audio with any reverb, effect processor or VST you come up with. Its better to add things later than not being able to remove things later.
IR / Convolution reverb
A common practise in sound design is applying an Impulse respondse (IR) Reverb to a recording. A IR reverb uses the actual reverb of a room. like the name suggests, an impulse, like a loud clap or a starters pistol, triggers a decay. The charactaristics of a room can be applied to any sound source this way. The less room in a recording the better the results will be when you use a IR reverb. There are IR kits featuring crazy rooms like a pharao's tombe chamber in a pyramid, but you can also choose what seat you'd like to have in carnegie hall. More info aboutIR reverbs
