Removal of transition bands from narrow speech passbands through very steep filtering has made it possible to isolate and determine (for the first time) intelligibility of critical bandwidth as well as subcritical bandwidth speech. These rectangular bands have unique intelligibilities when heard singly, paired, or in various multiband arrays spanning the speech spectrum. Thus, a particular sparse spectral array of unfamiliar everyday sentences in this study has demonstrated 98% intelligibility up to 100 dB. Some theoretical and practical applications are suggested.
通过非常陡峭的滤波从窄语音通带中去除过渡带，使得首次能够分离并确定临界带宽以及亚临界带宽语音的可懂度。当单独聆听、成对聆听或以跨越语音频谱的各种多频段阵列形式聆听时，这些矩形频段具有独特的可懂度。因此，本研究中一组特定的、由不熟悉的日常句子组成的稀疏频谱阵列，在高达100分贝的情况下展现出了98%的可懂度。文中还提出了一些理论和实际应用。
