Why is Shure SM58 vocal microphone so popular? Here is an answer:
By recording live sound source with microphone , we have one inconsistency. This is around hum and unnecessary room ambient sounds. When we edit the sound, it`s easy to add effects, but eliminate these from original recordings is impossible without removing neseccary frequencies.
How to find solution to the problem?
Professional Sound Recording Studios used special panels to covering walls and roof. Also there are built in isolation booths which provide excellent sound control. For home usage these not a most handy solutions. However, if you have a fully separate room at home, you can design it like recording studio. But it`s very expensive settlement.
I was find a pretty good solution, works well for recording individual sound source.
Mic-Booth – a little booth, are installed around the microphone. This “tube“ are fixed with microphone to stand and are opened only in the direction of sound source. The mic-booth can eliminate room hum and unnecessary ambient sounds during recording process. Moreover, recording quality will be similar to professional studio.
And the best thing are: It can make without expensive spending.
I got the idea from Horlan Hagan, who made a “Porta-Booth“
– a portable recording booth, which is nice by mobile recording.
My general fiction was making a local recording booth, which have a possibility to install to usual mic stand. I needn`t it for portable usage not at all.
I decided to make it a round shape, because it`s more sightly for hang up. By rounded shape, it needs fewer makings and will be anymore lightweight for microphone stand.
Stuff needed for building a booth
- 1 sheet 50×600x600mm acoustic foam
- piece a fabric for casingl
- construction for fixing to stand
How to make a Mic-Booth
To get the best result, use two-inch thick ”Pyramid” style acoustic foam. It`s not good idea to replace it with mattress foam, which made for butt bump.
Optimal casing size: diameter 320mm & depth 320mm. I made it first unnecessarily depth, like can see on the upper picture.
First you need to do a little needle work, afterwards cut the foam fit to measure. You can get 4 suitable pieces from a foam list (2 for tube & 2 for rump). These pieces may hook up with carpet tape, here’s how you have again 2 pieces. Now can put foam into the tube and that’s done. Lastly, think how fix it to microphone stand. Probably, you find a best fitting solution for you. I was welding a construction by steel tube and wire.
My new Mic-Booth is done, and it works pretty well. Below can hear a difference by recordings with- and without a booth, used Samson C03 Condenser Microphone (switched to cardioid pattern).
