Animal Ears 🦇 Yileyo ndlela izilwane ezizwa ngayo
U-ilulwane uzwa kanjani?
Eptesicus fuscus
Lizingela ebumnyameni lifunda i-echo yokukhala kwalo, izikhathi ezinhlanu ngaphezu kophahla lwakho.
Ngamafuphi
U-Ilulwane uzwa cishe kusukela ku-2.6 kHz kuya ku-100 kHz, futhi ubamba kangcono eduze kuka-20 kHz. Nge-Animal Ears ungathatha noma yimuphi umsindo wakho bese uwuzwa ngendlela ayizwa ngayo.
Ilulwane elikhulu elinsundu lifinyelela ku-100 000 Hz, izikhathi ezinhlanu zomkhawulo wakho, futhi ngakolunye uhlangothi cishe alizwa lutho ngaphansi kuka-2 600 Hz: imisindo ephansi ayilithinti nhlobo. Konke ukuzwa kwalo kwakhelwe into eyodwa: ukukhala nge-ultrasound bese lilalela i-echo ebuyayo. Ngaleyo echo libala ukuthi ilunda likude kangakanani, liya ngakuphi futhi ngasiphi isivinini — ebumnyameni obuphelele, izikhathi ezingamashumi ngomzuzwana.
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 | 2.6 kHz |
|---|---|
| Umsindo ophakeme kakhulu | 100 kHz |
| Umsindo awuzwa kacace kunayo yonke | 20 kHz |
| Okuzwa wena | 20 Hz – 20 kHz |
Izindlebe zakho vs. ezika-Ilulwane
Yebo: ubamba imisindo ephakeme kangangokuthi kuwe kuwukuthula okuphelele, kuze kube cishe 100 kHz. Uphahla lwakho lungu-20 kHz.

Ingabe u-Ilulwane uzwa izinto ongenakuzizwa wena?
U-Ilulwane ubamba konke kusukela ku-2.6 kHz (ophansi kakhulu) kuya ku-100 kHz (ophakeme kakhulu), futhi uzwa kacace kakhulu eduze kuka-20 kHz.
Yebo: ubamba imisindo ephakeme kangangokuthi kuwe kuwukuthula okuphelele, kuze kube cishe 100 kHz. Uphahla lwakho lungu-20 kHz.
Imibuzo evamile
Yimiphi imisindo ezwiwa ngu-Ilulwane?
U-Ilulwane ubamba konke kusukela ku-2.6 kHz (ophansi kakhulu) kuya ku-100 kHz (ophakeme kakhulu), futhi uzwa kacace kakhulu eduze kuka-20 kHz.
Ingabe u-Ilulwane uzwa izinto ongenakuzizwa wena?
Yebo: ubamba imisindo ephakeme kangangokuthi kuwe kuwukuthula okuphelele, kuze kube cishe 100 kHz. Uphahla lwakho lungu-20 kHz.
I-Animal Ears yenza kanjani ukuthi umsindo uzwakale njengoba u-Ilulwane ewuzwa?
Ososayensi balinganisile, izinga ngezinga, ukuthi umsindo kufanele ube mkhulu kangakanani ukuze u-Ilulwane 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
Igundane
Uhlala isitezi esisodwa ngaphezu kwakho: cishe uyisithulu ezwini lakho, umuhle kakhulu ku-ultrasound.
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.
