Sound Capture

The microphone captures sound waves from the surrounding environment, including both the speaker’s voice and any background noise.

Signal Processing

The microphone’s signal processor analyzes the incoming audio signals, distinguishing between the desired voice signal and unwanted background noise.

Noise Identification

The signal processor identifies frequencies and patterns associated with background noise, such as hums, buzzes, or ambient sounds.

Inverse Sound Wave Generation

The signal processor generates an inverse sound wave that matches the frequency and phase of the identified background noise.

Combination of Waves

The inverse sound wave is combined with the original audio signal, effectively canceling out the unwanted background noise.

Output

The processed audio signal, now with reduced background noise, is transmitted to the desired output device, such as a speaker, headset, or recording device.

Adaptive Adjustment

Some noise-canceling microphones employ adaptive algorithms that continuously monitor the audio environment and adjust the noise cancellation settings in real-time to optimize performance.
