"Introduction to sound adjustment" equalizer ... Tips for correcting disturbance

One of the important items for improving the sound of car audio is this corner that explains "sound adjustment".Currently, we are introducing the method of "equalizer adjustment".This time, I will tell you how to operate the 13 band type "equalizer".

By the way, last time, I introduced how to grasp "disturbance of characteristics".This time, this time, I will explain how to correct "disturbance of characteristics".

There is one absolute tips for correction.It is "adjusted from a low bandwidth."The reason is as follows.

The sound is composed of a component called “basic sound” that determines the pitch, and a component called “overtone” that determines the tone.In addition, "basic tone" and "overtone" are related to integer.For example, the sound of "A (la)" used in tuning such as guitars is about 440 Hz in terms of frequency.In other words, the "basic tone" is 440 Hz, the 2x 880 Hz, the 3x 1.32kHz, the four -fold 1.76kHz ... the sound of these frequencies is on the "basic sound" as a "overtone".

In addition, “overtones” are greatly influenced by “basic sounds”.If the "basic sound" is disturbed for some reason, that will also affect the "overtone".If the foundation is shaken, the one on it will also be unstable.The same thing happens in the sound.

Therefore, the following phenomena also occur.For example, when the 800Hz band of "equalizer" has a peak, if the "basic sound" is disturbed, the peak will not be eliminated even if the 800Hz band is lowered ...It can happen.

Therefore, when performing correction operation, it is a rule to adjust from a low band.Operating a low band can also be resolved at the same time.And so, the higher band will no longer need to touch.Once you touch it, it can rather disturb the characteristics.

"The equalizer adjustment is from a low band."Don't forget.

This time I will do this.Next time, we will continue explaining the operation method of "equalizer".looking forward to.
