Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current sound suppression technologies lack intuitive user interfaces for monitoring and controlling the separation of ambient noise and speech content, often providing only binary or momentary noise reduction options without clear visualization of the suppression effect.
Innovation Solution
A method and system that determine a sound suppression mode by sampling input and output signals, using a mixture value to generate a control output signal, and display the processed information, allowing users to select the desired level of sound suppression through a graphical interface on a portable device, such as a smartphone, to manage ambient noise and speech content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If sound suppression processing is applied to separate ambient noise and speech content, then noise reduction effectiveness is improved, but user understanding and control of the suppression effect deteriorates due to lack of visualization
Solution Approach 1:
The patent uses color-coded visual representations to indicate different levels of sound suppression. The display shows visual feedback with color changes that correspond to the degree of noise reduction applied, allowing users to intuitively understand the suppression effect in real-time without complex technical explanations.
Solution Approach 2:
The system creates visual copies or representations of the audio processing effects. By displaying visual waveforms and suppression level indicators that mirror the actual audio processing, users can see a graphical representation of what is happening to the sound, making the invisible processing visible and understandable.
2Manufacturing precision
If detailed sound suppression control is provided, then sound quality is improved, but user interface complexity increases
Solution Approach 1:
The user interface dynamically adjusts based on the current audio processing state. Instead of presenting all possible controls simultaneously, the interface adapts to show only relevant controls and visualizations for the current suppression level, making complex functionality accessible through a simplified, context-aware display.
Solution Approach 2:
The sound suppression control is divided into discrete, manageable levels or segments. Rather than requiring continuous precise adjustment, the system presents segmented control options that are easier to navigate, with each segment representing a meaningful level of suppression that maintains sound quality without overwhelming the user.
3Measurement precision
If real-time monitoring of input and output signals is implemented, then user control precision is improved, but computational resources increase
Solution Approach 1:
The audio processing system performs multiple functions simultaneously using the same computational pipeline. The signal processing operations used for noise suppression are also utilized for monitoring and visualization purposes, eliminating the need for separate computational resources and achieving real-time monitoring energy-efficiently.

AI summary
In some embodiments, an audio system can be monitored by determining a sound suppression mode, and sampling information representative of an input signal and an output signal resulting from processing of the input signal in the sound suppression mode. The monitoring method can further include providing a display representative of the sampled information.
