| 中文摘要: |
| 时频分析已在信号分析、建模、合成、重构、滤波、压缩编码以及信号检测与参数估计、模式识别等得到了广泛应用。本文在简要介绍时一频分布的有关内容之后，综述了该方法在声学（如生理声学、医学超声学、水声学、语音声学等）中的主要应用及研究进展。 |
| 英文摘要: |
| The time-frequency analysis has been widely used for signal analysis,modelling, systhesis, reconstruction, time-varying filtering, compression, coding,signal detection, parameter estimation and pattern recognition, etc. After the simple introduction about the time-frequency analysis, this paper reviews the principal applications and researching advances of time-frequency analysis in acoustics. (eg. Bioacoustics, Medical Ultrasonics, Underwater Acoustics, Acoustic Phonetics, etc.) |
