Fraunhofer IKTS has accumulated know-how in the field of acoustic diagnostics over many years. With new approaches based on state-of-the-art AI methods, analysis and evaluation of technical and non-technical signals are possible. Individual service offers provide every interested party with the option of selecting a suitable offer for effective quality control or condition monitoring.

Detection software

The detection software used for pattern recognition runs on Windows and Linux. It automatically assigns recorded signals emitted by test objects to classes (e.g., good/bad or new/worn/defective) and can estimate parameters, such as remaining lifetime or material properties. In addition, it allows evaluation to be performed on successive signal events (e.g., switching noise or speech).


Hardware modules

Hardware modules enable variable, mobile measurements and are ideal for non-stationary test activities. They offer the same performance as the detection software does and are suitable for portable data acquisition.


Training software

With the training software, the customer can independently create new models (other series with other properties for the same part or new part types) and adapt the detection software to them.


Customer-specific development

Fraunhofer IKTS offers complete customized system solutions. Based on customer requirements, a concept for a system (consisting of sensors, electronics, hardware, and software) is created and realized at IKTS. The systems can be installed in test stations on production lines and used as in-line test systems.
