Due to the resonance characteristics of the room, the difference in the sound absorption coefficient of the sound absorbing material to the sound frequency, and the uneven frequency response characteristics of the speaker system, the problem that the sound of some frequencies is too strong and the sound of some frequencies is insufficient may occur. Therefore, the frequency response characteristics of the room must be adjusted.
There are two ways to balance the room: the adjustment of the human ear sounds is difficult, difficult to master, and must have rich practical experience and very familiar program source, and it is related to the sound pressure level when adjusting, and the age of the listener. Also relevant. Another method is to make objective measurements and adjustments with a pink noise source and an audio spectrum analyzer.
1. Equalizer adjustment method:
Subwoofer: 20Hz-40Hz, strong and powerful when appropriate. Controls the sound of thunder, bass drums, organ and bass. Excessive promotion can make music confusing.
Bass: 40Hz-150Hz, is the basic part of the sound, its energy accounts for 70% of the entire audio energy, is an important component of the performance of music style. When appropriate, the bass is relaxed and the sound is full and soft. When it is not enough, the sound is thin, 150Hz. When it is excessively lifted, the sound will be boring, the brightness will decrease, and the nasal sound will be enhanced.
Mid-bass: 150Hz-500Hz, is the structural part of the sound. The voice is located at this position. When it is insufficient, the singing sound will be drowned by the music. The sound is soft and weak. When it is properly raised, it will feel strong and powerful, and improve the intensity and loudness of the sound. Excessive boosting will make the bass hard, and 3-6dB overshoot at 300Hz. If you add reverb, it will seriously affect the clarity of the sound.
Midrange: 500Hz-2KHz, containing the low harmonics and overtones of most instruments, is the characteristic sound of snare drums and percussion instruments. The sound is clear and bright when appropriate, and the sound is awkward when not enough. A phone-like sound is produced when over-promoted.
Middle and high-pitched sound: 2KHz-5KHz, which is the characteristic sound of the string (the sound of the bow and the string of the string, the sound of the finger of the play string). When the sound is insufficient, the penetrating power of the sound is lowered. When it is too strong, the recognition of the language syllable is masked.
Treble: 7KHz-8KHz, is the frequency that affects the sound layering. Excessive ascension will make the piccolo and flute sound prominent, the language's teeth will be aggravated and the tone will be hairy.
Extremely high: 8KHz-10KHz
When appropriate, the triangle and the fork have a high metal permeability, and the rhythm of the sand clock is clearly distinguishable. Excessive lifting will make the sound unnatural and easily burn high-frequency units.
2. The sound of a balanced sound should be:
Below 150Hz (bass) should be full, soft and flexible;
150Hz-50Hz (mid-bass) should be thick and powerful, not turbid;
500Hz-5KHz (medium and high) should be bright and not hard;
Above 5KHz (treble) should be slender, smooth and not sharp.
When the whole frequency response is flat: the sound is naturally full and flexible, and the level is clear and smooth. When the frequency response is multi-peak valley: the sound is rough and turbid, the treble is harsh and hairy, and the layered sound is easy to generate feedback whistling.
3. The acoustic characteristics of the frequency:
30~60Hz Dirty If there is no considerable loudness, it is difficult for the human ear to feel.
60~100Hz heavy and heavy 80Hz can produce a strong "heavy sense" effect, high loudness will not give a comfortable feeling, can give people a strong stimulation.
100~200Hz fullness
200~500Hz strength is easy to cause the snoring of the snoring.
500~1KHz It is obvious that if it is increased by 10dB near 800Hz, it will obviously produce a sense of noisy and narrow.
1K~2KHz Translucent 2800Kz has the brightest relationship.
2K~4Kz Sharp 6800Hz forms a screaming, sharp feeling.
4K~8Kz crisp 3400Hz is easy to cause hearing fatigue.
8K~16Kz slender >7.5KHz sound is clear and slender.
