Summary:
|
This new technical report studies the subjective test methodology for noise suppression performance in Internet real-time communication (RTC) services. These services are utilized in a wide range of applications, such as remote meetings, education, and medical care. The report identifies challenges associated with evaluating the noise suppression performance of Internet RTC services, emphasizing the growing demand for high-quality audio in various noisy environments. It highlights the limitations of existing testing methods and investigates a comprehensive subjective test methodology to address these deficiencies. The report covers several key aspects: scene coverage, test indicators, and hardware devices. It is expected to enable users to make informed comparisons of noise suppression performance across Internet RTC services, encourage advancements in product quality, and stimulate the growth of the RTC industry. The proposed subjective test methodology breaks down the noise suppression performance of Internet RTC into five independent test indicators: audio quality degradation, noise suppression amount, residual noise amount, residual noise stability, and noise convergence speed. The report outlines the following steps for future work in this research area:
Step 1: Investigate the methodology for assessing subjective quality within the noise suppression performance for Internet RTC. Develop the independent test indicators that cover all the aspects of subjective quality, such as audio quality degradation, noise suppression ability, noise convergence speed, and others. Conduct in-depth research, necessary experimental demonstrations, and practical validations;
Step 2: Initiate and encourage further potential research topics, including the objective evaluation methods mentioned in Step 1, and the subjective test methodologies for other modules in Internet RTC (e.g., echo cancellation with and without far-end noise, gain control, network transmission, and others).
