==AMBIENT SOUND LEVEL CONTROL - A simplified explanation of the abstract==


This abstract first appeared for US patent application 20240303031 titled 'AMBIENT SOUND LEVEL CONTROL

The abstract describes a patent application for a wearable audio device that includes a speaker, sensor, input, processor, and filter to provide an attenuated audio output signal based on sensed characteristics of the initial audio output signal and external noise.

* The wearable audio device has at least one speaker for audio output.
* It includes sensors to detect characteristics of the initial audio output signal and external noise.
* An input allows the user to select a desired level of noise attenuation.
* A processor analyzes sensor signals and user input to determine coefficients for noise attenuation.
* A filter then processes the audio signal based on the coefficients to produce an attenuated output.

Potential Applications:
- Noise cancellation in headphones or earbuds
- Enhancing audio quality in noisy environments
- Improving communication in crowded spaces

Problems Solved:
- Reducing external noise interference
- Providing a customizable noise attenuation solution
- Enhancing user experience in audio devices

Benefits:
- Improved audio clarity
- Personalized noise cancellation levels
- Enhanced user comfort in noisy settings

Commercial Applications:
Title: "Advanced Noise-Canceling Technology for Wearable Audio Devices"
This technology can be used in premium headphones, communication headsets, and audio accessories for professionals working in noisy environments. It can also be integrated into consumer headphones for everyday use.

Questions about the technology:
1. How does the wearable audio device differentiate between the initial audio output signal and external noise for noise cancellation?
2. What are the potential challenges in implementing this technology in different types of wearable audio devices?


==Original Abstract Submitted==

a wearable audio device can include at least one speaker to provide an initial audio output signal; at least one sensor arranged to: sense at least one characteristic of the initial audio output signal, sense noise external to the wearable audio device, and provide at least one sensor signal related to at least one characteristic of the sensed initial audio output signal and at least one characteristic of the sensed noise; at least one input arranged to accept an input related to a desired level of attenuation of the noise; a processor arranged to: receive the at least one sensor signal and the selected desired level of attenuation, select at least one coefficient from a coefficient table based on the at least one sensor signal or the selected desired level of attenuation, and provide an attenuation signal related to the selected at least one coefficient; and at least one filter arranged to receive the attenuation signal from the processor and produce a filtered audio signal based on the attenuation signal, wherein the at least one speaker is configured to provide an attenuated audio output based on the filtered audio signal.
