HANBOO SOLUTION / R&D & TESTING
Acoustic performance is claimed by many and measured by few. Our R&D Center runs automotive-standard NVH rigs and a full material lab in-house — and it is where Oxi-PAN carbon felt went from first trials to serial production. Development loops in days, not shipping cycles.

SOUND TRANSMISSION LOSS
Insulation performance of dash and floor constructions under impact excitation — the standard rig OEM acousticians use to compare suppliers. Connected data acquisition captures every run.
SOUND ABSORPTION COEFFICIENT
Reverberant absorption of felt systems across the automotive frequency range — the number behind every "quieter cabin" claim we make.
Measured absorption and transmission-loss curves for representative constructions are available on request — few suppliers share them; we do.
