For an Analysis of String Instrument's Sound Transmit , searched un instrument's (Geomungo) material characteristic , found a difference between Type of Microphone(Type of convert system) and place of Miking.
Also, searching for Geomungo's material and sound characteristic, Referenced to original two parts of thesis 'Analysis of String instrument's sound wave and characteristic'- 2. Analysis of Korean traditional instrument / Analysis of String instrument(3)(A research communication laboratory New media affiliated with Seoul university, 01/ 01/ 2002) and 'Geomungo's sound characteristic' (Dept. of Electronic engineering Seoul University/ Du, seo-jin, Kim, seung-mo) for apply and analysis infer the whole out of a part.
To put it in briefly,
Frist, On average Frequency Range of Geomungo's sound is between '58.270Hz ~ 466.16Hz', from playing technical skill 'Dae-jjum''s sound(Hitting sound is coming out when it Plays Geomungo 'Dae-jjum') is under the ‘12KHz’ .
Secend, Microphone placed three sides for recording - ① Soundbox located Bottom of Geomungo ② Upper board's frist Gwae ③ Using Suldae's Playing place 'Dae-mo'.
In conclusion, Approach to Natural sound recording is rather using two parts-Upper board's frist gwae, and Using Suldae's Playing place 'Dae-mo' than 'Soundbox Which located Bottom of Geomungo'.
At last, It depends on recording and individual differences.- But when we have to Recording soundbox's sound, it's much better to use 'Dynamic Microphone'(Could be feel soft sound), not too much close to the microphone, distance from 15cm.
Also, The whole string sound and Ambiance should be soundproof . - using 'Condencer Microphone' on Upper board's frist Gwae which carry out like Bridge. - Which is on Geomungo's 'Dae-Mo' Miking has to have Mixing process, so it could be more fully and natural sound.
