I remember a buzzing in my ears.

我记得耳朵里满是。

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

计算机让她心烦。

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。

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

我住在一个飞机附近, 昼夜都能听到飞机飞过。

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

高通滤波器可以去除最低频率，对低频被放大，容易形成房间，非常有帮助。
