Several tips for improving your listening ability
16k-20k: Overtones of musical instruments such as electronic chorus and guzheng piano.
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.
12k-16k: High-frequency overtones of percussion instruments such as cymbals, bells, tambourines, sand hammers, bronze brushes, and triangle irons.
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. This frequency is often beautified by an exciter.
8k-12k: Flute, oboe, trumpet, piccolo and other high-pitched instruments.
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.
4k-8k: Part of the female voice, and most of the wind instruments.
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.
2k-4k: Part of the female voice, and most of the wind instruments.
This frequency has a strong penetrating power. The resonant frequency of the human ear cavity is 1 to 4 KHz, 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.
1.2k
1.2kHz can be a little more appropriate, but it should not exceed 3dB, which can improve the brightness of the sound, but too much will make the sound hard.
1kHz
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: The amplitude of the vocal and part of the percussion instrument 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.
300-500: The voice of the vocal in the 300-500 Hz band is mainly the vocal (singing, recitation). This band can express the thickness and intensity of the vocal, but the vocals are bright and clear, otherwise it is thin and turbid.
150-300: This frequency of male voice affects the intensity of the sound, especially the strength of the male voice. This frequency is the low-frequency pitch frequency of the male voice, and it is also the root audio frequency of the music. 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.
60-100: Drums, timpani, and a few instruments with very low frequencies such as piano, cello, and large.
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.
20-60: Explosion, Disco
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.
