Ndeupi musiyano uripo pakati pemahedhifoni epamusoro uye mahedhifoni ekupedzisira?

Mahedhifoni akafanana.Iwo epamusoro-soroperformzviri nani, sekutaura.Saka, chii chaizvo chinoita mahedhifoniperformanceinosanganisira?

(1) Frequency Range:Vanhu vanoona ruzha sekuchinja kwemhepo.Pane nzira mbiri dzakakosha dzekupimwa/kumiririrwa nadzo.Themariyeiyi pressure (inodanwaSPL), uye Frequency iyo shanduko iyi inoitika.Manzwiro emunhu anogona kuona pamusoro pe100 dB (Decibel) yekuchinja mukatiSPL, uye manzwi ane frequencies pakati20 uye 20,000 Hz (Hertz/Cycles pasekondi).

Saka, chinangwa chekutanga chehedhifoni ndechekupa ruzivo rwemutsindo rwunofukidza yakawanda yekuona kwevanhu sezvinobvira.Asi vashoma vanogona, nekuti, nekuda kwekuganhurirwa mune tekinoroji yekugadzira, miganhu pamutengo wekugadzira, miganhu yemitemo yefizikisi kuzadzisa icho chinangwa hachisi chinhu chiri nyore.

Vagadziri vanoedza kugadzira mahedhifoni, anogona kuburitsa chero frequency pakati pe20 ne20,000 Hz, pane chero ruzha runodikanwa (inoti 20 kusvika 120 dB), ichida huwandu hwakafanana hwesimba (inoratidza yunifomu yemagetsi hunhu), pasina mhedzisiro (kukanganisa nezvimwe. )

Sezvo vagadziri vasingakwanise kunyatso kuzadzisa chinangwa, ivo (vanofanirwa) kutaura kuti chii chiri kutsauka kubva pamusoro apa muchigadzirwa chavo.Vanopa iyi stat muchimiro che+-dBs.Kutsauka uku zvakare chikamu chezvakajairwa zvakatemwa.

Sayenzi yeacoustics inotaura kuti mahedhifoni akakodzera (kana chero mudziyo wekuburitsa ruzha wechinhu ichocho) unofanirwa kubereka zviri pedyo nezvinodiwa sezvinobvira.Munyika yeaudio maitiro akadai emudziyo anonziMutongi-flat frequency mhinduro. Asi mukuita, hapana hunhu hwakadaro hunogona kuwana kana kufarirwa nevatengi.Ruzhinji rwevashandisi vekupedzisira vanosarudza zvishoma zveBoom-and-sizzlemuzwi ravo.Saka, vanogadzira dzimwe nguvatunechigadzirwa chavo kuti vabudise mhando yeruzha rwakasiyana nerwakanaka.Vagadziri vakasiyana vane dudziro yakasiyana yekuti chigadzirwa chavo chinofanira kunzwika sei, kana vagadziri vanogadzira zvigadzirwa zvavo vachichengeta zvimwe zvikamu zvevatengi mupfungwa.Saka kunyangwe semahedhifoni akasiyana anoitirwa kunzwika zvakanaka, anowanzo tsauka kubva pamaitiro avo akanaka.Vamwe vanogadzira vanogara vachiomerera kune yakatarwa mhando yekugadzira (inodanwakutaura) yeruzha rwakadhindwazve muchigadzirwa chavo.Kurira kwakadaro kunonzikurira kwembayemugadziri.

Parizvino, zvinofanirwa kunge zviri pachena kuti nei mahedhifoni akasiyana achiita / achifanira kunzwika zvakasiyana.Mubvunzo unotevera ndewekuti - chii chinoita mahedhifoni epamusoro anoita zvakasiyana.Zvakanaka, ivo kana

(a)buritsa iri padyo neruzha rwakakodzera (iyo yakaoma kwazvo kuita)
(b)budisa inzwi rinova USP yavo
(c)zvibate nenzira yakakodzera kune imwe application (specialized products).

(2) Kukanganisa:Distortion iko kusakwanisa kwehedhifoni kuburitsa chaizvo noti (iyo frequency, amplitude) yairi kukumbirwa kugadzira.Kukanganisa kunoratidzwa muchimiro chezana uye kazhinji chikamu chetsanangudzo.Kukanganisa kazhinji kusingadiwi.Zvigadzirwa zvisina kukanganisa zvishoma zvakaoma kugadzira, saka zvinodhura zvakanyanya.

(3) SPL:Zvigadzirwa zvinogona kuita zvakanaka pakakwirira SPLs kana pasi SPLs zvakaoma kugadzira.Saka vanodhura zvakanyanya.Ichi chinowanzoregeredzwa chemichina yegudzanzwi, iyo inofanira kunge iri asi, zvinosuruvarisa, haisi chikamu chezvakajairwa zvakatemwa.

(4) Zvishandiso zvinoenderana:Munyika yakanaka, mahedhifoni akakodzera anotamba zvakanaka nechero mimwe michina.Sezvineiwo, handizvo.Kugadzira mahedhifoni anogona kutamba zvakaenzana nemimwe michina yemhando dzakasiyana kwakaoma zvakanyanya.Mamwe mafoni epamusoro anoedza kuvanyore kutyaira, ichiri kugadzira ruzha rwemhando yepamusoro.

Vanoti, humbowo hwepudding huri pakudya.Izvi zvinobata chokwadi zvakanaka kana zvasvika pakubereka kurira.Kunyangwe iyo yepamusoro-soro yemusoro yakakosha mutengo wayo kana kwete inogona kungotongwa nekuiteerera.

Mahedhifoni epamusoro anopa aruzivo rwe visceral, imwe inogona kuvakushungurudza mweya, uye kunyangezvemweya.Yakanaka mahedhifoni vane kugonakutakurisa kuendanzvimbo yekurekodha yepakutanga, uye kuita kuti unzweuripo.Pane pfungwa yepalpabilitymune ruzha ruchaita kuti nzvimbo yese ive mhenyu.Izvo zvese izvo zvinoenderana neiyo rig yese iri kuteerera (headphone chete haigone kuita mashiripiti ese).Kazhinji pfungwa yechokwadi yaunowana kubva kune rig ibasa rekuti yakawanda sei mari uye kushanda nesimba kwakapinda mairi.
