Smart hardware that is easy to integrate
The Oldenburg Branch for Hearing, Speech and Audio Technology HSA of Fraunhofer IDMT develops hardware and software for recording and processing acoustic data in both cabled and wireless networks for all sectors.
The systems are assembled so that they meet the requirements of the respective market and of customer-specific applications. This begins with the selection of suitable sensor elements, computing platforms, housing, power supply and communication capacities and continues in the area of software. Corresponding processes are deployed depending on the application, e. g. signal preprocessing, noise cancellation, localisation of sound sources or data reduction. In addition, modern machine learning and artificial intelligence methods as well as classical algorithms are used as software modules for modern service architectures.
The sensor solutions are capable of processing large amounts of data on-premises. This relieves the load on communication channels and at the same time satisfies data protection and privacy requirements.
User group-specific interfaces and gateways for end users and experts round off the sensor systems and make them operable.
Acoustic sensor networks
For complex applications, acoustic sensor networks can be built. Meta-information forwarded from individual smart sensors enable the spatial, temporal and statistical modelling of acoustic events as well as conflation with multimodal information of other types on a central server.
The performance of smart acoustic sensor systems will improve even more in the future through the integration of AI-capable microelectronics. Last but not least, we are constantly improving our systems via research and development projects.
Multimodality is the technology of the future: To better map more complex situations, we are already linking acoustic information with other sensor modalities. The combination of different sensors makes it possible to obtain more comprehensive information.
