英语翻译
1 most speaker systems require rather heavy boost and the lowest frequencies due to the large amount of air that must be moved.
However,speaker woofer cones resonate between 45-60Hz where output is higher so do not boost at 150Hz,less boost at 400Hz.
2 due to sound-wave reflections between the front and rear windshields of a typical vehicle,there may be heavy loss between 700Hz to 1.3KHz so moderate boost here is very effective and will create more "presence"for vocalists.
3 the mid-range from 3to 6KHz should not require much change from flat most speakers work well here .Adjust per your taste.
4 due to limitation in human hearings.sound above 8KHz is not heard very well.Moderate boost at1KHz adds a crisp character when percussion instrument are present.

多数扬声器系统在使大量空气产生振动时,需要很大激励和最低的频率.
但是,低音扬声器锥体在45-60Hz产生共鸣,此时的输出很高,所以激励的量要在150Hz至400Hz之间.
2 due to sound-wave reflections between the front and rear windshields of a typical vehicle,there may be heavy loss between 700Hz to 1.3KHz so moderate boost here is very effective and will create more "presence"for vocalists.
在声波在一个典型汽车的前后挡风玻璃间反射时,可能会有700Hz至1.3KHz的巨大损耗,所以在这里,适度的激励会起很大作用,为歌手(的声音)做更多地保留.
3 the mid-range from 3to 6KHz should not require much change from flat most speakers work well here .Adjust per your taste.
3至6KHz的中间段不需要做更多的改变,多数扬声器在个频率间都能很好地工作.根据你的需要调整(即可).
4 due to limitation in human hearings.sound above 8KHz is not heard very well.Moderate boost at1KHz adds a crisp character when percussion instrument are present.
根据人类听力的极限,8KHz以上的声音基本听不到.当打击乐器都在场时,可以1KHz增加一个脆性特征的适度激励.
