Acoustic Compound Protection System
ACOMPRIS
Static kind of infrastructure is often vulnerable to attacks by either small arms fire (SAF) or mortars. The objects could be for instance a military forward operating base, an embassy or a post from the United Nations. As attacks may occur all the time, persistent and affordable protection is required. Especially when inhibited by civilians, ease of operations use and maintenance become more important. Often installed in remote places far away from the electricity grid, power consumption is an issue.

A Global Standard for Acoustic Absorption Measurements
Alpha Cabin
The Alpha Cabin has been especially designed for the measurement of acoustic absorption properties of materials and components used for the noise insulation of vehicles. The Alpha Cabin is significantly smaller than normal reverberation rooms and therefore ideally suited to use within limited space capacities. The acoustic absorption of the Alpha Cabin itself is also very low: Thanks to the high level of sound insulation, background noise in the frequency range of interest is kept to a minimum.

Acoustic Calibrators
When you're ready to take noise measurements, it's strongly recommended that you perform a field calibration using an Acoustic Calibrator. You should calibrate your sound meter before you start to measure, and then once you've finished you should perform a reference check against the calibrator and make note of any drift that has occured. You can find out more about performing Field Calibrators by reading this post and watching a short video.

Programmable Voltage Reference Plug-In
ProDAQ 3202
The ProDAQ 3202 voltage reference card is used in the ProDAQ 3180 ultra-performance motherboards and LXI function card carriers. The ProDAQ 3202 voltage reference card is plugged directly onto the motherboard or carrier and can distribute the reference voltage to all ProDAQ function cards via two signal lines. This allows the distribution as a differential signal to overcome possible noise pick-up.
