The computer made a buzzing noise that she found off-putting.

计算发出的让她心烦。

My mouth dry, I flew closer, expecting the zing of bullets and the whump of heavyweapons fire.

我口很干，飞得更低了，期盼着子弹呼啸和重武器开火的。

I live near an airport and the zoom of passing planes can be heard night and day.

我住在一个飞近, 昼夜都能听飞飞过的。

The high pass filter cuts the lowest frequencies. This cab be useful in rooms where low frecuencies are amplified and tend to be "boomy".

通滤波器可以去除最低频率，对低频被放大，容易形成的房间，非常有帮助。
