Noise, Vibration & Harshness Laboratory

• The semi anechoic chamber is designed for NC15/20 dBA.
• A room which create free field conditions above reflective plane.
• Above a certain frequency all sound wave that hit the walls or ceiling of the chamber will be absorbed.
• This chamber can be used for vehicle testing with rolling round so that the vehicle may be driven.
• The semi anechoic chamber forms a controlled environment with the surrounding acoustic conditions behaving as a sterile version of the real world.
• Accurate measurement of the sound inside and outside the vehicle can be made under operating conditions

Model: LAN XI 3160-A-042 & Noise Generator

A combination of inputs and generator outputs make a complete stand-alone analyzer test system. The module is ideal for applications where system excitation is required - such as audio and electro-acoustic test applications.

Type 3160 comes in two basic variants, offering the choice between 2 inputs/2 outputs and 4 inputs/2 outputs. All input and output channels have a frequency range of DC to 51.2 kHz.
