Noise control materials can be tested in terms of their sound absorption and transmission properties in a plane wave tube to
guarantee highly repeatable test conditions. This provides information of materials’ acoustic properties for validating and calibrating
computational methods used to predict the acoustic performance of multi-layer systems.

Features

· Comprehensive solution for evaluating both sound absorption and sound transmission properties

· Determination of normal incidence absorption coefficient and normal specific impedance based on ISO 10534-2 and ASTM E1050
and ASTM E2611

· Measurement data and results can be conveniently saved to familiar Microsoft® Excel workbooks for customized reporting and further post-processing

· PULSE platform ensures exceptional measurement accuracy.

Uses

· To develop noise control products

· To verify compliance with specifications

· To benchmark competitive products

· To help select the most adequate treatment

· To provide input information to analytical and numerical tools (for example, FEM, BEM, SEA) for the prediction of sound field in acoustic cavities

(for example, vehicle cabin noise, aircraft cabin noise)
