Sound Signal Processing Method and Headset Device - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240251197 titled 'Sound Signal Processing Method and Headset Device
The patent application describes a sound signal processing method and a headset device that includes a target filter and a first audio processing unit. The target filter processes an external sound signal collected by an external microphone to obtain an environmental sound attenuation signal and a voice attenuation signal. The first audio processing unit removes a second external environmental sound signal and a second voice signal from an in-ear sound signal collected by an ear microphone based on the environmental sound attenuation signal and the voice attenuation signal to obtain a blocking signal, which is then transmitted to a feedback filter. The feedback filter generates an inverted noise signal corresponding to the blocking signal and plays it through a speaker.
- Target filter processes external sound signal for environmental sound attenuation and voice attenuation signals.
- First audio processing unit removes external environmental sound and voice signals from in-ear sound signal.
- Blocking signal is generated and transmitted to feedback filter.
- Feedback filter generates inverted noise signal and plays it through a speaker.
Potential Applications: - Noise cancellation in headsets and earphones. - Enhancing voice clarity in communication devices. - Improving audio quality in noisy environments.
Problems Solved: - Minimizing background noise interference. - Enhancing voice recognition and communication clarity.
Benefits: - Improved sound quality in audio devices. - Enhanced user experience in noisy environments. - Better communication efficiency.
Commercial Applications: Title: Advanced Noise Cancellation Technology for Headsets This technology can be used in: - Headphones and earphones for consumers. - Communication devices for professionals. - Audio equipment for recording studios.
Questions about the technology: 1. How does the target filter differentiate between environmental sound and voice signals? - The target filter uses algorithms to analyze the frequency and amplitude of the signals to distinguish between environmental sound and voice signals. 2. What is the role of the feedback filter in the sound processing method? - The feedback filter generates an inverted noise signal to cancel out unwanted sounds and improve audio quality.
Original Abstract Submitted
a sound signal processing method and a headset device. a target filter and a first audio processing unit are added. the target filter processes an external sound signal collected by an external microphone, to obtain an environmental sound attenuation signal and a voice attenuation signal. the first audio processing unit removes, based on the environmental sound attenuation signal and the voice attenuation signal, a second external environmental sound signal and a second voice signal from an in-ear sound signal collected by an error microphone, to obtain a blocking signal, and transmits the blocking signal to a feedback filter. the feedback filter may generate an inverted noise signal corresponding to the blocking signal and play the inverted noise signal through a speaker.
