IAV SonicSeek

IAV SonicSeek can distinguish between normal and abnormal noises. The system not only helps to prevent potential damage, but also reduces the number of unnecessary maintenance and repair work. IAV SonicSeek learns different acoustic “signatures,” trains corresponding neural networks, and, on this basis, enables the detection of acoustic anomalies and their classification into predefined categories.

AI hears what you don’t hear!

In the automotive sector, for example, SonicSeek can be integrated into modern vehicles via the infotainment system and record live acoustic data via the on-board microphones. This data can then be transmitted to cloud computing services for further analysis. This allows sources of error to be quickly identified and damage to vehicles and people to be prevented, from production and quality assurance to private use by customers.

However, it is not only vehicle manufacturers who benefit from IAV SonicSeek. The solution delivers valuable results in all industries where mechanical systems are used. Microphones can be implemented in production machines, wind turbines, or aircraft, which then record analysis data, also via live transmission, and immediately detect malfunctions through acoustic diagnosis. Local analysis of the data directly in the monitored system (edge computing) is also possible.

What is SonicSeek?

Development of a neural network structure: In collaboration with the Technical University of Braunschweig, we have researched a wide range of neural network structures to determine which ones are best suited to overcoming the challenges of acoustic diagnosis. Our unique solution features a specially parameterized combination of convolutional and recurrent network layers.

High performance thanks to cloud-based processing pipeline: Through numerous optimization iterations, we have continuously refined preprocessing, AI training, and postprocessing. The entire process chain is integrated into a powerful, cloud-based processing pipeline. This enables us to provide a cost-efficient and scalable solution.

IAV SonicSeek in practice

IAV SonicSeek can be used in various industries and fields of application. In the automotive context, the following areas benefit:

• NVH optimization in development
• New end customer experience and functions
• Predictive maintenance
• After-sales service
• Quality assurance in production

Other industries in which IAV SonicSeek brings real added value: (wind) energy, marine, production machinery, transportation (rail, aerospace, elevators)

How can you benefit from IAV SonicSeek?

In an extensive analysis phase, we get to the bottom of your individual requirements and needs in order to identify opportunities and limitations, derive use cases, and identify possible impacts on your business. Acoustic recordings are then created and annotated—manually or semi-automatically—to suit your project exactly. This is the training input for our specially adapted neural network. Our cloud-based pipeline helps to find the optimal configuration and the best hyperparameters to optimize the resulting recognition and error rates. These are calculated according to scientific standards for a neutral comparison. With our complementary tooling, such as the IAV SonicSeek Audio Analyzer, we can visualize details and evaluate why a particular class was or was not recognized.
