AUDIO LIMITER - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240314486 titled 'AUDIO LIMITER
- Simplified Explanation:**
The patent application discusses techniques for dynamically adjusting an audio limiter in an active noise reduction (ANR) audio output device based on the fit between the device and the user's ear or head.
- Key Features and Innovation:**
- Adaptive adjustment of the audio limiter based on the quality of the seal between the earcup and the user's ear or head.
- Limiting of lower frequency portions of the audio signal when the fit is poor to reduce distortion.
- No limiting of the low frequency portion of the audio signal when the fit is good.
- Potential Applications:**
This technology can be applied in headphones, earphones, hearing aids, and other audio devices to enhance user experience by dynamically adjusting audio output based on the fit.
- Problems Solved:**
The technology addresses the issue of audio distortion caused by poor fit between the device and the user's ear or head, ensuring optimal sound quality.
- Benefits:**
- Improved audio quality and user experience.
- Reduction of audio distortion.
- Adaptive adjustment based on user comfort.
- Commercial Applications:**
Potential commercial applications include high-end headphones, professional audio equipment, and consumer electronics where audio quality is a key selling point.
- Prior Art:**
Prior art related to this technology may include patents or research on adaptive audio processing in headphones and earphones.
- Frequently Updated Research:**
Stay updated on advancements in audio processing algorithms, sensor technologies for fit detection, and user comfort in wearable devices.
- Questions about the Technology:**
1. How does the technology determine the state of the device relative to the user? 2. What are the potential challenges in implementing this technology in different types of audio devices?
Original Abstract Submitted
aspects of the present disclosure provide techniques, including devices and system implementing the techniques, to dynamically adjust an audio limiter in an anr audio output device. the audio limiter adaptively adjusts how much and when to limit incoming audio based on a determined state of the device relative to a user wearing the device. the state of the device is determined based on the quality of the seal or fit between the earcup and the user's ear or head. when the fit is poor or leaky, the audio limiter limits the lower frequency portions of the incoming audio signal in an effort to mitigate distortion. advantageously, when the fit is good, the audio limiter does not limit or reduce the amount of limiting of the low frequency portion of the audio signal.
