Description

A user-friendly kit for quick, non-destructive acoustic material testing, such as measurements of noise insulation constructions

This kit makes fast measurements of the acoustic properties of materials without having to remove a material sample. The kit consists of an easy-to-use hand-held instrument, a LAN-XI data acquisition front end, and PC software. Because it can measure objects in situ, it is ideal for verification after installation of acoustic treatments, and for quality control after all manufacturing processes are complete.
USE SCENARIOS

Quality assurance checks of aircraft engine nacelle liners on the production line
Measuring acoustic properties of aircraft interiors and cabin trim materials, such as attenuation and transmission loss
Evaluating sound insulation material installations in wind tunnels for aerospace or automotive research
Standard coupon tests using material samples to establish transmission loss, such as for automotive sound deadening materials

USE

The instrument has a sound source activation switch and status indicator integrated in the handle. An automated pass/fail routine allows production line operators to simply hold the instrument in contact with the in situ test article, and then receive a clear go/no go signal from an LED. Measurements are also viewable on a PC in real-time for ease of monitoring. The PC software has dedicated routines for measuring key quality control parameters.
