DETECTION AND SUPPRESSION OF HOWL SPEECH SIGNAL - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240096340 titled 'DETECTION AND SUPPRESSION OF HOWL SPEECH SIGNAL
Simplified Explanation
The system described in the patent application suppresses howl in a device, such as an artificial reality headset, by detecting the presence of howl in the audio content using an adaptive notch filter and reducing the gain of specific frequencies to eliminate the howl.
- The system uses an adaptive notch filter to detect the presence of howl in the audio content.
- The system reduces the gain of specific frequencies in the audio content to suppress the howl.
- The system may also monitor the flatness of the signal or use tonality detection based on linear prediction to detect the presence of howl.
Potential Applications
The technology can be applied in various devices that use microphones and speakers, such as communication devices, audio recording equipment, and smart home devices.
Problems Solved
1. Eliminates howling noise in audio devices, improving the overall audio quality. 2. Prevents discomfort or annoyance caused by howling noise during audio playback.
Benefits
1. Improved audio quality without howling noise interference. 2. Enhanced user experience with clear and uninterrupted audio playback.
Potential Commercial Applications
Optimizing audio devices for better performance and user satisfaction. SEO Optimized Title: Commercial Applications of Howl Suppression Technology
Possible Prior Art
One possible prior art could be noise cancellation technology used in audio devices to reduce background noise and improve audio quality.
Unanswered Questions
How does the system adapt to different levels of howl in the audio content?
The patent application does not provide specific details on how the system adjusts the gain reduction based on the severity of the howl. Further information on this adaptive process would be beneficial.
Are there any limitations to the effectiveness of the howl suppression system?
The patent application does not mention any potential limitations or challenges that the system may face in certain scenarios. Understanding the boundaries of the technology's effectiveness would be important for potential users or developers.
Original Abstract Submitted
a system suppresses howl in a device including microphones and speakers, for example, an artificial reality headset. a speaker of the device presents audio content. the audio content presented by the speaker is received by a microphone of the device thereby creating a howl in certain situations. the system detects the presence of the howl in a region of the audio content using an adaptive notch filter. the system suppresses the howl by reducing gain of one or more frequencies of the audio content. the system may detect presence of the howl by monitoring flatness of the signal. the system may detect presence of the howl based on tonality detection based on linear prediction
