摘　　要：科学高效的技战术统计方法是羽毛球技战术研究的有力保障,尤其是临场比赛中,教练员和运动员及时获取比赛过程的技战术统计结果可能成为接下来赢得比赛的关键。以李在福的教学视频作为研究对象,通过录像分析法、专家访谈法、文献资料法,对视频中的技术声音进行频谱分析,利用Video converter软件将wmv格式的视频转换为支持频谱分析的wav格式的音频,对照视频资料,利用Audacity软件对音频资料进行频谱分析,进而建立羽毛球技术声波数据库,利用Sigmal plot对数据库中的声波主频率进行综合对比分析,研究发现,杀球的频谱段在1100赫兹以上,抽球的频谱段在900~1100赫兹之间,扑球的频谱段在500~600赫兹之间,搓球则主要分布在300~400赫兹之间,可见,杀球、抽球、扑球、搓球的音频主频率存在明显差异,因此,在技战术统计分析过程中,我们可以将击球声音的主频率分析作为击球种类快速识别的工具,达到了数据输入自动化,结果输出快速化。Scientific and effective technique and tactic statistical method is a powerful guarantee for badminton technique research,especially in competition. Coach and player's timely obtaining of technique and tactic statistics of competition process may be key to coming competition victory. With Li Zaifu's teaching video as research object,transferring wmv format video to wav format audio supporting spectral analysis through video analysis software,contrasting with video literature,adopting Audacity software spectrum analysis to set up badminton acoustic database,using Sigmal plot comprehensive comparison and analysis of main frequency of sound wave in database,this thesis finds out that spectrum of smash is over 100 hertz,drive is between 900-1100 hertz,catching is between 500-600 hertz,chop is between 300-400 hertz,obvious audio main frequency difference exists among smash,drive,catching and chop. Therefore,in process of technique and tactic statistics analysis,hit ball sound main frequency analysis can be tool of hit type quick identification,reaching data input automation and result output rapidness.
