"The Quick Sound Field" vocal booth?

[waster]

Ekspertima je verovatno poznata knjiga "Handbook Of Acoustics" Alton Everesta.

Dok i sam kaže da su mali prostori nepogodni za vocal booth a za prave male gluvaće kaže da deluju zbunjujuće na naratora, govori i o konceptu "Quick Sound Field" ( live,but dry ) ?! i da se može primeniti na 4x6 ft (121x180cm) ili 6x8ft prostore.
Evo šta kažu:
The concept of a “Quick Sound FieldTM” (i.e., live, but dry), which comes from Acoustic Sciences Corporation can be applied to the small (e.g. 4 ? 6 ft or 6 ? 8 ft) voice recording room. The realization of a practical quick sound field is based on a multiplicity of half-round Tube TrapsTM as shown in Fig. 23-4. A quarter-round Trap is mounted in each wall-wall and ceiling-wall intersection to provide absorption to control the normal modes. Half-round traps alternate on the walls and ceiling with hard, reflective drywall
strips as wide as the traps (9-, 11-, or 16-inch). Even the door and window need to be covered in this way to avoid compromise of the sound field. Limited visibility is available through the window glass strips of reflecting surface. The floor remains untreated.
In the usual small recording room there are too few early reflections that result in noticeable comb-filter colorations. Reflections off the script stand or window, which normally cause comb-filter colorations, are overwhelmed by the swarm of diffuse reflections from the many reflecting surfaces of the room. The broad-band absorption of the half- round traps combines with the reflections from the hard areas between the traps to produce a dense, diffuse group of reflections immediately following the direct signal.

Ima i nekih grafikona ali me zanima šta mislite o ovom konceptu, da li je izvodljiv kod nas i koliko može da košta...

Pa ako vas baš zanima uradiću screen shotove i tih grafika...

Hvala unapred
