The study also evaluates the effects of FbAANC headset on speech intelligibility on a disyllabic Mandarin word discrimination test platform. We expect someone under the noisy environment in SNR equal 0,–5,–10,-15,-20 and –25 dB, the noise cancellation technique could either improve the speech discrimination effectively. Finally, the SNR below -10dB, the mean WDT score with FbAANC headset was superior to without FbAANC headset 13 to 32% through 30 subjects of normal hearing threshold for evaluation. These results suggest that the FbAANC headset would be useful for hearing protection in workplaces with high levels industrial noise.

同时，本论文亦透过华语双字词语音辨识力测验，以评估此噪音消除技术对於语音理解力的影响，期望在SNR为0，-5，-10，-15，-20和-25dB的环境下，暸解噪音消除技术能否有效提升语音辨识力；经过30位正常听力的受测者之评估，我们可以得到当讯噪比在-10 dB以下时，经过噪音消除后的语音辨识力成绩可明显地提升13 to 32%，因此，本噪音消除耳机确实可以作为耳机防护以提供给工人对抗高分贝的工厂噪音。

The second method is to structure a toeplitz matrix to approach the toeplitzed signal subspace under the rule of mimimum power of noise, when the algorithm is converged, the structured toeplitz matrix is a full rank matrix, the angle information of target are all reserved and the influence of noise is minimum at this time.
