The human ear is more sensitive to the timbre, and it can directly judge whether the sound is realistic or not. If the tone is not handled well, it will not only make the sound monotonous and boring, but also cause serious distortion of the instrument or singing, so the importance of tone treatment cannot be ignored. For male voices, most people`s voices are relatively deep and lack treble. In order to improve the clarity of singing, the frequency of 3kHz can generally be compensated for; for female voices, the treble appears too much and the voice is "spit." In order to make the sound louder and not too harsh, the 400Hz frequency component can generally be compensated.
Reverberation usually determines the length of the reverberation and has a direct impact on the color and clarity of the sound. Under normal circumstances, when the bass is singing, the reverberation time can be adjusted shorter to improve the clarity of the sound; if it is a soprano singing, the reverberation time can be appropriately extended to increase the color of the sound. For a concert venue, if the walls around the room are made of wooden materials, the reverberation time should be reduced at this time to prevent the sound from being blurred; conversely, if the walls around the room are made of wooden materials, the reverberation time should be reduced. The time should be adjusted lower to avoid ambiguity; on the contrary, if the room is hung with sound-absorbing materials such as flannel curtains, the reverberation time should be adjusted longer in such a room to prevent the sound from being dry. In addition, the size of the audience and the audience also has a great influence, because the costumes of the audience also have a great sound absorption effect. Therefore, the speaker and tuner can choose a suitable reverberation time between 1 and 2 seconds.
How to adjust the ratio of direct and reverberant components
Completely direct sound without reverberation output can not improve and beautify the sound. Therefore, this situation is usually only used in meetings or recitations. Appropriately increasing the proportion of reverberation sound components is conducive to simulating the natural reverberation sound, making the sound full and beautiful, and can increase the three-dimensional sense of the audience and the crowd. Completely reverberant sound without direct sound component output will cause the sound to "color" and cause serious distortion, that is to say, it is as ambiguous as the sound heard in the bathroom or bathhouse. People in the industry call it "bathroom." effect". Therefore, if there is no special requirement, the knob can be adjusted to the middle position, that is, the ratio of the direct sound component to the reverberant sound component is 1:1, so that not only will the sound not be distorted, but it will also have a certain reverberation effect. .
