一般中低档音响和自制的发烧组合,都存在一种在小音量欣赏音乐时,音质明显下降的感觉,这是因为人的听觉在小音量时对中音的听感变化不大,而对高低音的感觉却十分的迟钝,且灵敏度下降很快的原因所致。因此,一些音响采用了衰减中音的办法来达到高中低音平衡的目的,但由于衰减了中音,使得中音单薄,听感效果不是很好。下面向读者介绍一种响度控制器,可消除这一缺点。其设计思想是:在不衰减中音的前提下,按音量的大小和人的听感来调节高低音的提升量,从而达到弥补小音量时高低音的不足,使整个音域在小音量时也能达到较好听感的效果。
Generally low-end audio and home-made fever combination, there is a feeling of music at a small volume to enjoy a clear decline in sound quality, it is because people’s hearing in a small volume of the sound of the tenor did not change much, while the high Bass feeling is very slow, and the sensitivity dropped quickly due to the reasons. As a result, some acoustics use the mid-range attenuation method to achieve the high school bass balance. However, the mid-range is too weak due to the attenuation of the mid-range. Let’s introduce the reader to a loudness controller that eliminates this drawback. The design idea is: under the premise of not attenuating the alto, according to the size of the volume and the human sense of hearing to adjust the amount of bass boost, so as to make up for the lack of bass at low volume, so that the entire range at a small volume Can achieve better sense of hearing the effect.
