Kool Music Box.
The subwoofer mainly adjusts the size of 125hz. General equalizers come with various types of configurations, such as electronic music, rock, etc. I like the configuration I adjusted myself (see picture) very much and use it all the time. The sound is more realistic. You can try it too! The number below is the frequency of the sound, for example, 125 is 125 Hz, and 4K is 4000 Hz. The following is a brief introduction to the characteristics of sounds of various frequencies. For more specific information, you can go to the Baidu Encyclopedia "Equalizer" entry. You can make some adjustments according to your own preferences. For example, if you like heavy bass, turn up the 125. Frequency range (Hz): 16k-20k Hearing impact: Many people may not be able to hear this frequency. Therefore, not being able to hear this frequency does not mean that the equipment cannot play back, and of course it does not mean that your hearing is not good enough. Only a few people can hear 20kHz. This frequency can affect the brightness of high frequencies and the overall sense of space. Too little of this frequency will make people feel a bit dull, while too much of this frequency will cause a sense of erraticness and easily cause hearing fatigue. Representative musical instruments: electronic chorus, overtones of guzheng piano and other musical instruments. Frequency range (Hz): 12k-16k Hearing impact: This frequency can affect the overall color sense. The so-called "pine scent" of the violin is determined by this frequency. If this frequency is too dim, the instrument will lose its personality. If it is too high, it will produce a burr feeling. During post-processing, an exciter is often used to beautify this frequency. Representative musical instruments: high-frequency overtones of percussion instruments such as cymbals, bells, tambourines, maracas, copper brushes, and triangles. Frequency range (Hz): 8k-12k Hearing impact: 8~12kHz is the high-pitched area of ??music, and the feeling is most sensitive to the high-frequency performance of speakers. Appropriate prominence (below 5dB) will greatly help the level and color of the sound, and will also make people feel that the treble is rich. However, too much will increase the background noise. For example, the noise of the system (sound card, sound source) will be obviously displayed, and it will also make people feel that the sound is sharp and hairy. If this section is lacking, the sound will lack appeal and energy. Representative musical instruments: flute, oboe, trumpet, piccolo and other high-pitched wind instruments. Frequency range (Hz): 4k-8k Listening impact: This frequency most affects the clarity and brightness of speech. If there is a lack of this frequency component, the timbre will become dull; if there is too much of this frequency component, the timbre will become dull. It's sharp, and the person may have a sibilance. This frequency is usually beautified by a compressor. Representative musical instruments: some female voices, and most wind instruments. Frequency band (Hz): 2k-4k Hearing impact: This frequency has 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 there are too few empty frequency components, the hearing ability will become worse and the speech will appear blurred. If this frequency component is too strong, it will produce the feeling of coughing. 2~4kHz has a great influence on the brightness of the sound, and this sound is generally not suitable for attenuation. This section has a greater impact on the level of music. Appropriate improvement can improve the brightness and clarity of the sound, but it cannot be too prominent at 4kHz, otherwise the sibilance of the female voice will be too heavy. Representative musical instruments: some female voices, and most wind instruments. Frequency band (Hz): 1.2k Hearing impact: 1.2kHz can be appropriately more, but it should not exceed 3dB. It can improve the brightness of the sound, but too much will make the sound hard. Frequency band (Hz): 1k Hearing impact: 1 kHz is the standard reference frequency for audio equipment testing. The parameters usually given in audio equipment are tested at 1 kHz. This is the frequency to which the human ear is most sensitive. Frequency band (Hz): 800 Hearing impact: This frequency amplitude affects the intensity of the timbre. If this frequency is full, the timbre will appear strong and powerful; if this frequency is insufficient, the timbre will appear loose, that is, the component characteristics below 800Hz will be prominent, and the low-frequency components will be obvious; and if this frequency is too much, a larynx will appear. Sound.
If there are too many throat sounds, the individuality of the voice will be lost. Appropriate throat sounds can increase the sexiness. Therefore, sound engineers call this frequency a "dangerous frequency" and should be used with caution. Representative musical instruments: vocals, some percussion instruments. Frequency band (Hz): 300-500 Hearing impact: The sound in the 300-500Hz frequency band mainly expresses the human voice (singing, reciting). This frequency band can express the thickness and strength of the human voice. If it is good, the voice will be bright and clear. Clear, otherwise thin and cloudy. Representative musical instrument: human voice. Frequency range (Hz): 150-300 Hearing impact: This frequency affects the strength of the sound, especially the strength of the male voice. This frequency is the low-frequency fundamental frequency of the male voice, and it is also the root frequency of the chords in the music. The sound in the 80-160Hz frequency band mainly expresses the richness of music. If the sound reproduction effect in this part is good, the music will feel thick and confident. If this part performs well, the lack of bass below 80Hz won't even be felt. If the performance is not good, the music will feel dull or even weak. It is the playback upper limit of many subwoofer speakers. This can be used to determine the upper frequency limit of your subwoofer speaker. Representative instrument: male voice. Frequency range (Hz): 60-100 Hearing impact: This frequency affects the thickness of the sound and is the fundamental area of ??the bass. If this frequency is very full, the tone will appear thick and thick. If this frequency is insufficient, the timbre will become weak; if this frequency is too strong, the timbre will vibrate at a low frequency and feel like a roar. Representative musical instruments: bass drum, timpani, piano, cello, tuba and a few other instruments with extremely low frequencies. Frequency range (Hz): 0-60 Hearing impact: This frequency affects the sense of space of the timbre. This is because the fundamental tone of the music 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 speakers, this frequency is cut off to ensure the consistency and consistency of the sound.
