Describe according to the different spectral range of sound below.
60～100Hz: this band frequency influences the simple and honest sense of sound, is the fundamental tone district of bass.If this band frequency is very plentiful, tone color can seem, and abundant, mixed thick sense is strong.If this band frequency deficiency, tone color can become unable; And if this band frequency is strong excessively, low-frequency resonance sound can appear in tone color, and Hong toot sensation is arranged.
100～150Hz: this band frequency is the richness that influences tone color, if this band frequency composition strengthens, will produce a kind of room toot spatial impression, mixed thick sense altogether; If this band frequency composition lacks, it is thin, pale that tone color can become; If this band frequency composition is strong excessively, it is muddy that tone color will seem, the definition variation of voice.
150Hz～300Hz: this band frequency influences the dynamics of sound, especially the dynamics of male voice sound.This band frequency is the low-frequency degree fundamental frequency of male voice sound, also is the root voice frequency of chord in the musical sound simultaneously.If this band frequency composition lacks, tone color can seem feel like jelly, unstable, it is soft that voice then can become; If this band frequency composition is strong excessively, it is stiff and unnatural that sound can become, and do not have characteristic.
200～500Hz: medium and low frequency section decision sound dynamics, as surpass+5dB～10dB sound thickens, definition descends, drop-6～10dB sound lacks dynamics and shows thin, tone color is hard and narrow.
300～500Hz: this band frequency is the main range of sound frequency of voice.The amplitude of this band frequency is plentiful, and voice have dynamics.The cavity, not solid if this band frequency underswing, sound can seem; If this band frequency amplitude is strong excessively, it is dull that tone color can become, and low-frequency component lack comparatively speaking, and high frequency has become also less, and voice can become that to be similar in the phone tone color of sound the same, seem very dull.
500H～1KHz: frequency is the fundamental frequency zone of voice, is an important frequency range.If this band frequency is plentiful, the voice profile is bright and clear, and associative perception is good; If this band frequency insufficient amplitude, voice can produce a kind of contraction sense; If this band frequency is strong excessively, voice will produce a kind of outstanding forward sensation, make voice produce a kind of auditory perception that enters the people in advance.
800Hz: this Frequency and Amplitude influences the dynamics of tone color.If this frequency is plentiful, it is strong and powerful that tone color can seem; If this frequency deficiency, tone color will seem loose, just the following composition characteristic of 800Hz has been had outstanding performance, and low-frequency component just obviously; And if this frequency is too much, then can produce the gutturophony sense.Everybody has a cavum laryngis, and everybody has certain gutturophony, if the gutturophony composition in the tone color is too much, then can lose the tone color aesthetic feeling.
1～2KHz: the penetrating sense of this band frequency scope is obvious, and smooth and easy sense is strong.If this band frequency lacks, the then loose and tone color disconnection of tone color; If this band frequency is strong excessively, sound then has the sense of jump.
2～3KHz: this band frequency is to influence the most responsive frequency range of sound lightness, if this band frequency composition is abundant, then the lightness meeting of tone color strengthens, if this band frequency underswing, then the tone color dim dim moon bright that will become; And if this band frequency composition is strong excessively, that tone color will seem is stiff, harden, nature.1～3KHz medium-high frequency section plays an important role to lightness, definition and telepresenc, this frequency range surpasses+3～5dB can make the sound hardening, surpass+5～10dB and metallic sound can occur, drop-3～5dB can make the sound hardening, surpass+5～10dB and metallic sound can occur, drop-3～5dB can make tone color lose bright sense, and drop-5～10dB sound is stuffy, unintelligible.
3～4KHz: the penetration power of this frequency is very strong.The resonance frequency in people Er Er chamber is 1～4KHz, so people's ear also is highstrung to this frequency.If this band frequency composition is very few, hearing ability meeting variation, it is smudgy that voice seem.If this frequency content is strong excessively, then can produce the sensation of coughing sound.
Sex at the portable terminal holder, the low frequency of one male sex's sound spectrum is all abundanter, cause opposite side (being called end) at portable terminal, sound sounds can be stuffy, in this case, just can carry out the adjustment of low frequency, raise the spectrum gain between the low frequency part 100-500HZ, improve speech quality by FIR or iir filter.And the high frequency of female voice frequency spectrum is abundanter, cause the opposite side (called end) of portable terminal to sound that sound sends out point and ear-piercing, just can be by FIR or iir filter the spectrum gain between high frequency treatment 3000-4000HZ carry out certain forcing down and improve speech quality.
At the portable terminal holder age, one is divided into old age people's ages, the middle age, and the youth, children, according to the difference of hearing ability, the distribution of sound spectrum is also different, uses different FIR and iir filter parameters to regulate with regard to needing.Poor as the elderly's hearing, then need to improve the receiving intensity of receive path, if receiver (Receiver) device itself is supported auxiliary (the Hear Assist Carrier of t hearing, abbreviate HAC as) function, then can open the HAC of receiver, but guarantee volume within the acceptable scope, can not surpass people's the physiology threshold of pain, and can not exceed the power bracket of receiver or loud speaker.
