AI Technical Summary

Benefits of technology

This patented technology can improve noise reduction by making it better than existing methods that only work for short periods or at specific times during an audio recording session. It also provides accurate calculations with fast algorithms over time.

Problems solved by technology

This patented describes a technique called Microseismics that can be used to monitor underground conditions like tsunamis or explosions caused by fires. However, it struggles with accurate detection due to variations between short and longer wavelengths from these sources. To address this problem, there have been developed methods based on specific properties of microscope data including linear filtering techniques, Fourier transformation algorithms, and spectral analysis. These solutions aimed towards improving the efficiency and effectiveness of detecting events associated with mineral deposits.
