Animal Ears 🐁 Yileyo ndlela izilwane ezizwa ngayo
U-igundane uzwa kanjani?
Mus musculus
Uhlala isitezi esisodwa ngaphezu kwakho: cishe uyisithulu ezwini lakho, umuhle kakhulu ku-ultrasound.
Ngamafuphi
U-Igundane uzwa cishe kusukela ku-2.3 kHz kuya ku-85.5 kHz, futhi ubamba kangcono eduze kuka-16 kHz. Nge-Animal Ears ungathatha noma yimuphi umsindo wakho bese uwuzwa ngendlela ayizwa ngayo.
Igundane liphila emhlabeni ophakeme ocishe ungahlangani nowakho. Ngaphansi kuka-2 300 Hz cishe alizwa lutho, ngakho ingxenye enkulu yezwi lakho ifika kulo ifiphele noma ingafiki nhlobo. Ngakolunye uhlangothi likhuphuka kuze kube ngu-85 500 Hz, izikhathi ezine zophahla lwakho, futhi lizwela kakhulu eduze kuka-16 000 Hz. Lokho okubukeka njengokuthula ekhishini ebusuku kuwe — ukuklwebha, ukukhala, izingxoxo eziphelele phakathi kwamagundane — kulo kungumsindo womgwaqo.
I-Hertz (Hz)
Yimiphi imisindo ayizwayo
I-hertz ibala ukuthi umsindo udlidliza kangaki ngomzuzwana. Ukudlidliza okuncane = ophansi (ukuduma kwezulu, cishe u-30 Hz). Ukudlidliza okuningi = ophakeme (ukukhala kwe-microwave, cishe u-3 000 Hz). Futhi u-“1 kHz” kuyindlela emfushane yokusho u-1 000 Hz. Wena uzwa, ngokujwayelekile, kusukela ku-20 Hz kuya ku-20 000 Hz.
Umsindo ophansi uyaduma (cabanga ngokuduma kwezulu); umsindo ophakeme uyakhala kancane (cabanga ngomiyane). Lezi zinombolo ezintathu zikhombisa ukuthi lesi silwane sehla kangakanani, sikhuphuka kangakanani, futhi yiliphi izinga elizwa kacace kunazo zonke.
| Umsindo ophansi kakhulu | 2.3 kHz |
|---|---|
| Umsindo ophakeme kakhulu | 85.5 kHz |
| Umsindo awuzwa kacace kunayo yonke | 16 kHz |
| Okuzwa wena | 20 Hz – 20 kHz |
Izindlebe zakho vs. ezika-Igundane
Yebo: ubamba imisindo ephakeme kangangokuthi kuwe kuwukuthula okuphelele, kuze kube cishe 85.5 kHz. Uphahla lwakho lungu-20 kHz.

Ingabe u-Igundane uzwa izinto ongenakuzizwa wena?
U-Igundane ubamba konke kusukela ku-2.3 kHz (ophansi kakhulu) kuya ku-85.5 kHz (ophakeme kakhulu), futhi uzwa kacace kakhulu eduze kuka-16 kHz.
Yebo: ubamba imisindo ephakeme kangangokuthi kuwe kuwukuthula okuphelele, kuze kube cishe 85.5 kHz. Uphahla lwakho lungu-20 kHz.
Imibuzo evamile
Yimiphi imisindo ezwiwa ngu-Igundane?
U-Igundane ubamba konke kusukela ku-2.3 kHz (ophansi kakhulu) kuya ku-85.5 kHz (ophakeme kakhulu), futhi uzwa kacace kakhulu eduze kuka-16 kHz.

I-Animal Ears yenza kanjani ukuthi umsindo uzwakale njengoba u-Igundane ewuzwa?
Ososayensi balinganisile, izinga ngezinga, ukuthi umsindo kufanele ube mkhulu kangakanani ukuze u-Igundane aqale ukuwuzwa. Sithatha lolo jikelele siluvise ekurekhodweni kwakho njenge-equalizer enkulu: sikhuphula amazinga isilwane esiwazwa kahle, sehlise noma sisuse lawo angekho nhlobo kuso. Umphumela usondela kulokho esikubamba... kodwa usazongena ngezindlebe zakho.

I-ultrasound
Imisindo ephakeme kangangokuthi indlebe yakho ayisayibhali: ngaphezu kuka-20 000 Hz. Kuwe kuwukuthula okuphelele, kodwa inja, ikati noma ilulwane bayayizwa kahle. Impempe yezinja “ethule” ikhona lapho.

Ezinye izilwane
Ilulwane
Lizingela ebumnyameni lifunda i-echo yokukhala kwalo, izikhathi ezinhlanu ngaphezu kophahla lwakho.
Ikati
Ikhuphuka cishe izikhathi ezine ngaphezu kwakho: izwa isiteshi sangasese samagundane.
Ingwe
Izindlebe zekati ngobukhulu obukhulu, nokubhonga okuzwakala esifubeni ngaphambi kokuzwakala endlebeni.
Ifereti
Izingela emithumbini emnyama bhuqe, iholwa ukukhala okuphakeme kwesisulu.
