摘要

本文是关于TMK 2200型有轨电车的语音可理解度测试。掩蔽信号(噪音)是在电车行驶时记录的。在实验室记录Logatomes信号。测试信号是由噪声和对数信号混合产生的。受试者在实验室接受测试。测量结果分析表明，在现实条件下，在行驶过程中，通信质量极低。我们进行了额外的测试，降低了噪音水平。可理解性结果要好得多

Noise Influence on Quality of Communication in a Tram

This paper is about testing the intelligibility of speech during tram ride (tram model TMK 2200). Masking signal (noise) was recorded while driving in the tram. Logatomes signal was recorded in the laboratory. Test signal was produced by mixing of noise and logatomes signals. Subjects were tested in the laboratory. Measurement results analysis shows us that in realistic conditions, during the ride, the quality, of communication is extremely low. We conducted additional tests with reduced noise level. The intelligibility results were much better
