Measure the sound absorption rate and transmission loss of the main frequency band with a single acoustic tube!

The sound absorption rate and transmission loss in the main frequency range (100Hz to 5000Hz) can be measured at once using a single acoustic tube. Since there is no need for multiple measurements with different sizes of acoustic tubes and samples, data inconsistencies do not occur, and the labor required for sample preparation (cutting) and measurement can be significantly reduced.

basic information

■ Adoption of transparent acrylic for the sample support section Transparent acrylic is used for the sample support section of the acoustic tube. This allows for visual confirmation of the sample's installation status during measurement, significantly reducing measurement errors caused by incorrect sample installation. ■ Compatible with vertical incidence transmission loss measurement using the four-microphone method By replacing the sample support section with an optional tube for transmission loss measurement, it is possible to measure the vertical incidence transmission loss of samples standardized by ASTM E2611. ■ Significant reduction of the influence of sample plate vibration through a compliant support sample holder By using a uniquely developed compliant support sample holder, the impact of plate vibration caused by the sample's elasticity, which has been a longstanding issue, can be significantly reduced in the sound absorption rate measurement results. ■ Applicable standards ISO 10534-2, ASTM E1050, JIS A 1405-2 (sound absorption rate), ASTM E2611 (transmission loss) ● For more details, please refer to the catalog or contact us.
