Abstract
The noise masking system captures an ambient signal via a microphone and processes it to generate a dynamic masking signal delivered via a speaker. The system comprises a power spectrum analyser 6 for determining power per frequency, a peak extractor 9 for identifying dominant frequency components, a temporal control module 8 for characterising temporal components and a machine learning classifier 10 which may optionally receive the acoustic signal direct from the microphone, which detects sound types and acoustic environment characteristics, these inputs are sent to the synthesiser, which generates a masking signal whose spectral, temporal, and spatial properties are continuously adapting. The masking signal is generated using frequency-domain or time-domain synthesis techniques and shaped in accordance with psychoacoustic masking criteria. The system may further incorporate a noise cancellation system, and a personalisation model.
