AD93 Acoustic Duct 93 Series Acoustic Duct is designed to measure the characteristics
of an acoustical material such as sound absorber and sound barrier.
                           AD9301: Measurements of absorption ratio and transmission loss.                
  AD9302 : Measurements of absorption ratio.                                  
                     AD9303 : Measurements of absorption ratio and pavement absorption.
Features - Measurements of absorption ratio and transmission loss.
- Support data comparison using little sample.
- Develop the materials by measurement of absorption ratio and transmission loss.
- Analyze a void effect of the multi layered material.
- Develop a soundproof wall and enclosure.
- Analyze a reflection coefficient of the sound-absorbing material.
- Measure a sound absorption of the fixed surface such as walls directly.
- Predict an absorption ratio and a transmission loss of the multi layered structures.
