Low pafupipafupi ndi khalidwe kuwongola

Bass - mfundo kuphatikizapo osiyanasiyana kulira m'makutu a anthu. Pa avareji ndi mu osiyanasiyana kuchokera 20 Hz 20 kHz. Audiogram, zomwe kudziwa luso kuzindikira pakhomo m'munsi aliyense pafupipafupi, ndi makhalidwe awo munthu, kotero ife tikhoza kulankhula za pafupifupi kumva zowerengera. Kawirikawiri, ndi mafurikwense pansipa 40 Hz ndi pamwamba 16 kilohertz m'malo izititsogolera pa mtundu phokoso kuposa anamvera yokha.

Uthunthu kubereka ndi kufalitsa zipangizo ndi osiyana kwambiri, wosiyana ndi zofunika pa izo. Mwachitsanzo, foni zonse imabereka pafupipafupi phokoso la 200 Hz 3 kHz, ichi ndi chokwanira kwa bwino disassemble mawu onse a chubu kumapeto kapena, mu nkhani ya kugwiritsa ntchito zida za m'manja mwa cholankhulira. N'chimodzimodzinso otchedwa "mabelu" - okamba translational. Komabe, mu ulemu wa gulu pafupipafupi zapita muyezo dziko, chimene zipangizo kalasi Hi-Fi ayenera pafupipafupi gulu la 20 20000 Hz ndi onse.

otsika pafupipafupi mkuzamawu ntchito ambiri ngati gawo la madera pakompyuta zipangizo zosiyanasiyana mafakitale ndi zoweta, monga wailesi osiyana. Iwo makompyuta, ma TV, mawailesi, CD-player, ratsiyah, mafoni, okwerera foni ndi ena ambiri bwino kwa ife zinthu.

Makhalidwe waukulu mkuzamawu ali motere:

- linanena bungwe mphamvu. Masiku ano amaona mosiyana. Mwachitsanzo, kuti kulenga pa mfundo maloponimayuschego anthu voliyumu Kumwambamwamba, amene adzatha kusangalala, pa phukusi ndi wolandila kapena mkuzamawu, mukhoza kuwona wokhala kwathunthu manambala zinayi manambala amalembedwa «PMPO». Makalata amenewa ayenera mfundo zikutanthauza pachimake katundu, amene angapereke yochepa zida audio. Mphamvu yeniyeni - ndi kuchuluka omwe amaonetsetsa undistorted sine yoweyula mawonekedwe pa pafupipafupi 1,000 Hz ndi athandizira kwa mkuzamawu lapansi.

- kupotoza - mtengo kusonyeza mmene mafurikwense otsika mu mawonekedwe awo kuti siteji linanena bungwe isiyana ndi mbendera athandizira. Izi mwina chizindikiro chofunika kwambiri, kulankhula za mmene anapanga ndi makonda otsika-pafupipafupi mkuzamawu.

- Mphamvu osiyanasiyana. Mkhalidwe umenewu nkofunika kwambiri kwa zida mkulu-amplifying, limapereka chithunzithunzi cha phindu mmene m'mbali Zithunzi. M'mawu ena, osiyanasiyana mokwanira lonse wamphamvu adzakhala undistorted onse pafupipafupi otsika, kaya msinkhu wawo. Ndipo chete kwambiri, ndi phokoso mokweza kwambiri idzaseweredwe molondola. Khalidwe limeneli khalidwe la mikuza mawu chubu.

- pafupipafupi ayankhe. Pa anatchulidwa m'nkhani, inu mukhoza kuwonjezera mbali monga yunifolomu. Choncho, ndi molunjika mzere kufanana kwa abscissa sikelo pafupipafupi mu uthunthu opaleshoni.

magawo ameneŵa ndi khalidwe limene mafurikwense otsika ali chinaonekeranso chakale amveke zida. Mu ena katundu wamakono banja zitsanzo nyimbo pafupipafupi makhalidwe dala molakwika kulenga zotsatira mafashoni monga zigawo yoimba kuwongola kapena ultrahigh pafupipafupi, amene ali ingafooketse kumva ndi ubongo.
