Revolutionary sensors: Ilmenau research is changing the audio world!
Research team at TU Ilmenau is developing an innovative auditory system for optimized noise detection with minimal sensors.
Revolutionary sensors: Ilmenau research is changing the audio world!
An innovative research project at the Ilmenau School of Green Electronics aims to develop an artificial auditory system that uses a minimal number of sensors. Loud TU Ilmenau The team aims to cover a large area auditorily without recording sounds themselves. The innovative solution could be used primarily in industry, for example in workshops, as no sensitive conversation content is stored or passed on.
The system, which is currently being tested in the VR Lab of the Ilmenau Interactive Immersive Technologies Center (I3TC), also offers additional advantages in terms of data security. Instead of recording audio content directly, only information about noise sources and events is derived.
Technological advances and environmentally friendly approaches
A key goal of the project is to downsize the system's electronics to minimize environmental impact. Future applications could particularly lie in wearable devices or innovative hearing aids. In parallel to this project, several research teams are working on various aspects of acoustic sensing, which will be presented at conferences in the coming years. A current contribution from the Fraunhofer Society announces the investigation of the NeuroSensEar, a neuromorphic acoustic detection for highly developed hearing aids of the future, as in a report by IDMT mentioned.
These developments show that interest in smart acoustic sensors is constantly growing. Several publications are expected in 2025, covering topics such as assessing soundscapes using machine learning and the electroacoustic properties of experimental microphone designs.
Applications and advantages of soft sensors
Another important aspect of modern sensor technology are soft sensors, which analyze and process data directly at the sensor node without relying on cloud services. Improving data security, energy efficiency and responsiveness are key benefits that come with their use, such as EMFT reported.
Soft sensors can make real-time decisions and combine information from multiple physical sensors and AI models into a coherent signal. They find application in various areas including:
- Medizinische Diagnostik: Multisensorsysteme zur Vitalparametererfassung, die frühzeitig auf Veränderungen im Gesundheitszustand hinweisen.
- Maschinenüberwachung: Proaktive Wartung durch Zustandsschätzungen und Anomalieerkennung in industriellen Anwendungen.
- Umweltschutz: Reduktion des Energieverbrauchs und CO2-Bilanzverbesserung in industriellen Prozessen.
The interface between artificial intelligence and acoustic sensors shows impressive advances that are important for the future. With the potential to transform both industry and the medical field, developments in intelligent acoustic systems remain an exciting field of research.
