A table is provided below, and you can make a preliminary judgment based on this table.
Frequency range (Hz)
Listening to influence representative musical instruments
16k-20k
This frequency may not be heard by many people. Therefore, listening to this frequency does not mean that the equipment cannot be played back. Of course, it does not mean that your hearing is not good enough. Only a few people can hear 20 kHz. This frequency can affect the high-frequency brightness, as well as the overall sense of space. This frequency is too small to make people feel a little stuffy, too much will produce a sense of erratic, easy to produce hearing fatigue.
Overtones of musical instruments such as electronic chorus and guzheng piano.
12k-16k
This frequency can affect the overall color sense. The so-called "sweet scent" of the violin is determined by the frequency of this segment. This frequency is too bleak, which will cause the instrument to lose its personality. Too much will produce a tingling sensation. The high frequency overtones of percussion instruments such as cymbals, bells, tambourines, sand hammers, bronze brushes, and triangle irons are often beautified by exciters.
8k-12k
8 to 12 kHz is the high-pitched area of ​​music, and is most sensitive to the high-frequency performance of the sound. Appropriate highlighting (below 5dB) will greatly help the level and color of the sound, and will also make people feel high-pitched. However, too much will increase the background noise. For example, the noise of the system (sound card, sound source) will be clearly expressed, and the sound will be sharp and hairy. If this is lacking, the voice will lack appeal and vitality.
Flute, oboe, trumpet, piccolo, etc.
4k-8k
This frequency most affects the clarity and brightness of the speech. If the frequency component is missing, the tone becomes flat; if there are too many components in this frequency, the tone becomes sharp and the tooth may appear in the human body. This frequency is usually beautified by a compressor.
Part of the female voice, and most of the wind instruments.
2k-4k
This frequency has a strong penetrating power. The resonant frequency of the human ear cavity is 1∽4KHz, so the human ear is also very sensitive to this frequency. If the emptiness frequency component is too small, the hearing ability will be worse and the speech will be blurred. If this frequency component is too strong, it will produce a coughing sensation. 2 to 4 kHz has a great influence on the brightness of the sound, and this sound is generally not suitable for attenuation. This section has a great influence on the level of music. Appropriate improvement can improve the brightness and clarity of the sound, but there is not too much protrusion at 4 kHz, otherwise the female voice will be too heavy.
Part of the female voice, and most of the wind instruments.
1.2k
1.2kHz can be a little more appropriate, but should not exceed 3dB, can improve the brightness of the sound, but too much will make the sound hard
1k
1 kHz is the standard reference frequency for audio equipment testing, and the parameters usually given in audio equipment are tested at 1 kHz. This is the most sensitive frequency of the human ear.
800
This frequency amplitude affects the intensity of the tone. If this frequency is full, the tone will appear strong and powerful; if this frequency is insufficient, the tone will appear slack, that is, the characteristic characteristics below 800 Hz are outstanding, and the low frequency component is obvious; and if this frequency is too much, the throat will be produced. Sound sense. If the throat sound is too much, the personality of the voice will be lost, and the proper throat sound can increase the sexiness. Therefore, the sound engineer calls this frequency "dangerous frequency" and should be used with caution.
Vocal, partial percussion
300-500
The sound in the 300-500 Hz band is mainly for vocal (singing, recitation). This band can express the thickness and intensity of vocals, but the vocals are bright and clear, otherwise they are thin and turbid.
Vocal
150-300
This frequency affects the strength of the sound, especially the strength of the male voice. This frequency is the low-frequency pitch frequency of the male voice, and is also the root audio frequency of the chord in the tone. The sound in the 80-160 Hz band mainly expresses the thick feeling of music. If the sound is good in this part, the music will be thick and emboldened. If this part is good, if it is lacking below 80Hz, it will not even feel the lack of bass. If the performance is not good, the concert has a dull feeling, even if it is weak. It is the playback limit of many subwoofer speakers, which can be used to determine the upper limit of your subwoofer speaker frequency. Chinese home theater network male voice
60-100
This frequency affects the mixed feeling of the sound and is the pitch area of ​​the bass. If this frequency is full, the tone will look thick and thick. If the frequency is insufficient, the tone will become weak; if the frequency is too strong, the tone will have a low-frequency resonance and a roaring sound. Drums, timpani, and a few instruments with very low frequencies such as piano, cello, and large
20-60
This frequency affects the spatial sense of the tone, because the pitch of the tone is mostly above this frequency. This frequency is the resonant frequency of the room or hall. This frequency is difficult to express. In some HiFi stereos, this frequency is cut off to ensure the consistency and audibility of the sound.
1. The 20Hz--60Hz part of this promotion can give a strong feeling to the music, giving a very loud feeling, such as thunder. It is a powerful and powerful feeling in music. If the elevation is too high, it will be turbid, resulting in poor definition, especially for low-frequency response and low-frequency audio equipment.
2. The 60Hz--250Hz part is the low-frequency structure of the music, which contains the basic sound of the rhythm part, including the main sound of the pitch and rhythm sound. Its ratio to the high-pitched tone constitutes the balance of the tone structure. Raising this section will make the sound full, and excessive boost will make a rumble. Attenuating these two segments will make the sound thin.
3. The 250Hz--2KHz section contains the low-frequency harmonics of most instruments. If you increase too much, the sound will be like the sound in the phone. Excessive elevation of 600Hz and 1kHz will make the sound like a horn. If the 3kHz is raised too much, the speech recognition tone will be masked, that is, the articulation is unclear, and the lip sound "mbv" is difficult to distinguish. If you increase the 1kHz and 3kHz excessively, the sound will have a metallic feel. Since the human ear is sensitive to this frequency band, this segment is usually not adjusted, and excessively increasing this segment will cause hearing fatigue.
4. The 2KHz--4kHz part of this frequency is an intermediate frequency. If it is raised too high, it will cover the speech recognition tone, especially if the 3kHz elevation is too high, it will cause hearing fatigue.
5. 4kHz--5KHz section This is a field-sensing frequency band that affects the clarity of sounds such as languages ​​and instruments. Raising this frequency band makes people feel that the distance between the sound source and the listener is a little closer; if the attenuation is 5 kHz, the distance of the sound will be farther; if it is raised by 6 dB at around 5 kHz, the sound of the whole mixed sound will be made. The power is increased by 3dB.
6. The 6 kHz--16 kHz section controls the brightness, macro brightness and sharpness of the tone. Generally speaking, raising these segments makes the sound loud, but it is not clear. It is impossible to cause the tooth to be too heavy. When the sound is attenuated, the sound becomes clear, but the sound is not loud.
