  • Acoustic noise detection method and system using vibration sensor to detect acoustic noise
    Patent number: 12135233
    Abstract: A vibration sensor senses vibrations generated by an object to generate a noise signal. A processor obtains a structure vibration level spectrum from the noise signal, uses equalization parameters and A-weighting parameters to adjust the structure vibration level spectrum to generate a sound pressure level spectrum, and uses the sound pressure level spectrum to calculate a noise value of the object.
    Type: Grant
