问：当前Sharp面临的主要挑战是什么？ 答：The term frequency component is where BM25 gets clever. Rather than counting raw occurrences, it applies saturation — the score grows quickly at first but flattens out as frequency increases. A term appearing 5 times contributes much more than a term appearing once, but a term appearing 50 times contributes barely more than one appearing 20 times. This is controlled by the parameter k₁ (typically set between 1.2 and 2.0). Set it low and the saturation kicks in fast; set it high and raw frequency matters more. This single design choice is what makes BM25 resistant to keyword stuffing — repeating a word a hundred times in a document won’t game the score.

问：Sharp对行业格局会产生怎样的影响？ 答：For noise cancellation assessment, my colleague Parker Hall and I test earbuds in various environments, exposing them to noises from lawn equipment, vacuum cleaners, construction sites, traffic, and other local sounds, evaluating both noise-canceling and ambient modes. As audio professionals, we also test them in acoustically treated home studios against airplane drone simulations, vocal chatter, and specialized noise through studio monitors. Whenever feasible, I take test units on extended travels and flights to observe performance in authentic settings. Our objective is thorough field testing to ensure value for money.
展望未来，Sharp的发展趋势值得持续关注。专家建议，各方应加强协作创新，共同推动行业向更加健康、可持续的方向发展。
