LFA:低频衰减
“低频衰减”(Low Frequency Attenuation,常缩写为LFA)是指对低频信号进行衰减处理的一种技术,在电子工程和声学等领域中应用广泛。使用LFA这一缩写不仅便于书写和交流,也有助于专业人士在学术文献和技术文档中高效表达相关概念。
Low Frequency Attenuation具体释义
Low Frequency Attenuation的英文发音
例句
- Active noise control ( ANC ) technology has more advantages over passive noise control especially at low frequency noise attenuation, however there are few the practical applications.
- 有源消声技术对降低低频噪声有极大的优势,但实际应用的例子很少。
- Ground roll wave has characteristics of strong energy, low frequency and slow attenuation.
- 面波具有能量强、频率低、吸收衰减缓慢等特点。
- In low frequency band, the attenuation rate of guided electromagnetic waves are very low and increases slowly as frequency.
- 在低频段上,导行电磁波的衰减率很小,随频率的升高而缓慢增加,不论单线波模还是双线波模其近壁效应都很小。
- For an active sonar operating in shallow waters, reverberation is the main background interference, especially at low frequency. The transmission attenuation is small, but the reverberation is high.
- 对于主动探测,尤其在浅海,混响是一种主要背景干扰,低频的传输衰减小,混响也强。
- At low frequency, sonic wave has greater rate of attenuation.
- 在低频段,声波有较大的衰减变化率;
