为了利用软件实现噪声倍频程分析,提出了一种基于FFT的数字计权方法。
In order to realize a noise octave analysis by software, a digit weight method based on FFT is proposed.
同时运用1/3倍频程分析对比法和总加权加速度有效值法评价了拖拉机的乘坐舒适性。
The 1/3 octave bands and total weighted average are exploited to estimate the ride comfort of the tractor.
利用这一方法,可以以软件方式完成噪声倍频程分析的数字计权处理,并且能够实现系统误差修正。
Using this technique, digital weight and digital system error modification for noise octave analyzer can be realized by software.
解决噪声1/3倍频程、声功率、音调窄带谱,振动频谱等复杂功能的在线分析与处理。
A lot of complex functions, such as 1/3 octave analysis, sound power, tonality narrow band analysis, vibration spectrum, have been solved.
也就是说,我不推荐DWT的音乐和声音的分析,因为分析带被固定在一个倍频程,这简直是太宽做任何有意义的。
That being said, I don't recommend the DWT for music and sound analysis because the analysis bands are fixed at one-octave, which is simply too wide to do anything meaningful with.
