<80Hz
80Hz basically is the percussion instrument that gives priority to with low frequency in replay music below, for example bass drum, timpani, still have a few presence such as piano, cello, sousaphone the musical instrument of extremely low frequency, if this one part has good, the influence that did not admire to music also is not very big. It is not easy that this one part should weigh put away, taller also to the requirement of equipment. A lot of advanced material, good for expression 80 (or 80 the left and right sides) the frequency of Hz above paragraph music, aux would rather will 80 (or 80 the left and right sides) flat excision drops the frequency under Hz, lest replay is bad, affect main frequency instead paragraph the effect. Extremely floor level of hearing of ear of humanness of low frequency 20Hz, can test floor level of your replay of equipment low frequency, the replay floor level that the 25Hz in low frequency, 31.5Hz, Hz, 40Hz, 50Hz and 63Hz are a lot of sound box, if your sound box is in these frequency,somewhere sound drops quickly, the floor level of replay of sound box low frequency that shows this frequency is you.80 - 160Hz
Be in 80 - 160Hz frequency paragraph the rich sense that sound basically behaves music, acoustics is if effect of this part replay is good, can feel thick, know how things stand and feel confident of handling them enrages music. If this part is behaved well, when be lacked under 80Hz, won't feel devoid bass even. If performance is bad, the concert has depressing feeling, it is weak even. It is the replay upper limit of sound box of a lot of bass artillery piece, provide this to be able to judge upper limit of your frequency of sound box of bass artillery piece.300 - 500Hz
In 300 - 500Hz frequency paragraph sound basically is expressional voice (sing, reading) , this frequency paragraph go up the ply that can behave voice and strength, good a voice is bright, clear, otherwise feeble, muddy.800Hz
This paragraph of common device has sowed 800Hz easily, but should notice not overmuch. This paragraph of frequency that if pass much word,can feel acoustics is noisy narrow, high shortage administrative levels, low frequency is plump degree insufficient.1000Hz
The standard reference frequency that 1 KHz is sound equipment test, the parameter that gives out in sound equipment normally is check below 1 KHz.1200Hz
1.2kHz is OK and many bits properer, but unfavorable exceed 3dB, can raise audio to be spent brightly, but, overmuch meeting is sound hair is good.2000-4000Hz
2 ～ 4kHz is very big to audio brightness influence, this paragraph of sound shoulds not be commonly damply. This paragraph is bigger to administrative levels influence of music, proper promotion can raise audio to be spent brightly with definition, but what there cannot have been many when 4kHz is outstanding, otherwise the tine sound of female voice will be overweight.Previous12 Next
