SoundPrint® - Monitoring for Buildings & Structures

SoundPrint® is a patented innovative monitoring technology that can detect and locate failures in high-strength steel wire, strand or cable through continuous, non-intrusive remote monitoring.


The tendon systems of post-tensioned concrete building structures such as many multi-storey commercial buildings and car-parks are vulnerable to moisture ingress. Such ingress, which can occur at any time, can cause corrosion-induced failures in these structures. Current non-destructive evaluation techniques are ineffective for evaluating the condition of post-tensioned systems. Furthermore, intrusive inspection techniques whilst useful in the initial assessment of a structure can only provide a sampling of the condition of the wire strands that form the tendons.

SoundPrint® continuously monitors every wire strand in a building and will identify the time and location of their failures. Since SoundPrint can also determine the frequency of wire failures, statistical techniques can be used to estimate future rates of failure in different parts of a building.

How it works

Step 1

SoundPrint Acoustic Monitoring system is installed on a Bridge or Structure.

Step 4

Data from events that has passed preliminary filtering processes is transferred to our data-processing centre to be further examined.

Step 2

Sensors measure the dynamic energy release when tensioned wires fail.

Step 5

Through a combination of applied proprietary software, and highly trained professional analysis, acoustic events are assigned a time, location, and specific classification.

Step 3

Onsite Data Acquisition Unit performs preliminary hardware filtering and real-time pre-processing rejecting superfluous acoustic event data.

Step 6

If and when the event is classified as noteworthy, electronic alerts are sent, via email, to the client. The data is immediately accessible on the 3D GIS website, and reports can be custom generated

Information on Demand

Through the SoundPrint web site, clients can now access data from their structures directly. Using the intuitive interface, managers can custom-design their own reports, generated in real time. Acoustic events can be examined and replayed in real audio format, and presentation-quality reports for multiple sites can be viewed and printed.

Using our powerful and versatile GIS-based Management Interface, information from other instrumentation systems can also be integrated into the SoundPrint acquisition and processing system. Information from entire infrastructure management networks can be viewed on the client’s custom web site. This provides managers with desktop access to a single-source, reliable service for all instrumentation requirements, providing information where it's needed, when it’s needed.
