Abstract:
A method for determining the presence of unwanted signal components in an acoustic signal, comprises: receiving a first microphone signal derived from an acoustic signal, applying the first microphone signal to a first signal processing path having a first transfer function to provide a first output, receiving a second microphone signal derived from the acoustic signal, applying the second microphone signal to a second signal processing path having a second transfer function to provide a second output, wherein the second transfer function has a different degree of linearity from the first transfer function, and determining the presence of unwanted signal components in the acoustic signal based on a comparison of the first output and the second output.

Claim (Index 8):
A method for determining the presence of unwanted signal components in an acoustic signal, comprising:\n receiving a first microphone signal derived from an acoustic signal, applying the first microphone signal to a first signal processing path having a first transfer function to provide a first output, receiving a second microphone signal derived from the acoustic signal, applying the second microphone signal to a second signal processing path having a second transfer function to provide a second output, configuring the first and second signal processing paths such that the second transfer function has a greater linear range of operation than the first transfer function, and determining the presence of unwanted signal components in the acoustic signal based on a comparison of the first output and the second output, wherein the first and second signal processing paths comprise at least one signal processing component having nonlinear characteristics, wherein configuring the first and second signal processing paths comprises adjusting the operation of at least one signal processing component having nonlinear characteristics.
