We examined the effect of frequency ratios on the discrimination of patterns of alternating pure tones (ABABA). Listeners heard a repeating pattern presented in transposition (same frequency ratios between successive tones, different absolute frequencies) and were required to indicate when the pattern changed (different frequency ratios and absolute frequencies). Changes from patterns with simple frequency ratios to those with more complex ratios were more readily detected than were changes from complex ratios to simpler ratios.
我们研究了频率比在交替纯音模式（ABABA）辨别中的作用。受试者聆听了以移调形式呈现的重复模式（连续音调之间的频率比相同，但绝对频率不同），并被要求指出模式何时发生变化（频率比和绝对频率均不同）。与从复杂频率比模式变为简单频率比模式相比，从简单频率比模式变为更复杂频率比模式的变化更容易被察觉。
