采用多导同步声学分析的方法对５０名歌唱者、６０名播音员进行了声学测试，播音员的胸部共振效果较好，能量集中在２０００～４０００Ｈｚ，而歌唱者头部能量较高，一般集中在３０００Ｈｚ处。歌唱者的共振峰值一般比播音员要低，两者有着不同的共鸣方式。 Acoustic tests were performed on 50 singers and 60 broadcasters using multi-guided simultaneous acoustic analysis. The announcer’s chest resonance was better, with energy concentrated at 2000-4000 Hz, while the singer’s head had higher energy and was generally concentrated At 3000Hz. The singer peak is generally lower than the announcer, and both have different ways of resonating.
