Animal Ears 🦡 Yileyo ndlela izilwane ezizwa ngayo
U-ifereti uzwa kanjani?
Mustela putorius furo
Izingela emithumbini emnyama bhuqe, iholwa ukukhala okuphakeme kwesisulu.
Ngamafuphi
U-Ifereti uzwa cishe kusukela ku-36 Hz kuya ku-44 kHz, futhi ubamba kangcono eduze kuka-12 kHz. Nge-Animal Ears ungathatha noma yimuphi umsindo wakho bese uwuzwa ngendlela ayizwa ngayo.
I-ferret izingela ngaphakathi emigodini, ebumnyameni, lapho ukubona kungasizi ngalutho. Ukuzwa kwayo kufaka kusukela ku-36 kuya ku-44 000 Hz futhi kubukhali kakhulu eduze kuka-12 000 Hz, phezulu kakhulu kunokwakho (iphuzu lakho elingcono kakhulu ngu-3 000). Leyo ndawo yiyona ngqo yokukhala kwamagundane. Ngamanye amazwi: emthunjini omnyama bhuqe, i-ferret iyazi ukuthi isisulu sikuphi ngenxa yomsindo omncane esiwenzayo lapho sinyakaza.
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 | 36 Hz |
|---|---|
| Umsindo ophakeme kakhulu | 44 kHz |
| Umsindo awuzwa kacace kunayo yonke | 12 kHz |
| Okuzwa wena | 20 Hz – 20 kHz |
Izindlebe zakho vs. ezika-Ifereti
Yebo: ubamba imisindo ephakeme kangangokuthi kuwe kuwukuthula okuphelele, kuze kube cishe 44 kHz. Uphahla lwakho lungu-20 kHz.

Digitised from Kelly et al. (1986); 60 dB SPL criterion (36 Hz–44 kHz), best ~0 dB near 12 kHz.
Ingabe u-Ifereti uzwa izinto ongenakuzizwa wena?
U-Ifereti ubamba konke kusukela ku-36 Hz (ophansi kakhulu) kuya ku-44 kHz (ophakeme kakhulu), futhi uzwa kacace kakhulu eduze kuka-12 kHz.
Yebo: ubamba imisindo ephakeme kangangokuthi kuwe kuwukuthula okuphelele, kuze kube cishe 44 kHz. Uphahla lwakho lungu-20 kHz.
Imibuzo evamile
Yimiphi imisindo ezwiwa ngu-Ifereti?
U-Ifereti ubamba konke kusukela ku-36 Hz (ophansi kakhulu) kuya ku-44 kHz (ophakeme kakhulu), futhi uzwa kacace kakhulu eduze kuka-12 kHz.

I-Animal Ears yenza kanjani ukuthi umsindo uzwakale njengoba u-Ifereti ewuzwa?
Ososayensi balinganisile, izinga ngezinga, ukuthi umsindo kufanele ube mkhulu kangakanani ukuze u-Ifereti 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.

Uphahla lwayo luphindwe kabili kunolwakho: unina namazinyane akhuluma ngaphezu komkhawulo wakho.
Ingwejeje
Ixwayisa nge-ultrasound: isignali isilwane esizingelayo esingakaze siyizwe.
Inyamazane yeqhwa
Ukuzwa okubanzi nokulinganayo kwendawo enkulu, engenalutho nethule.
Inyamazane
Izindlebe eziphendukayo ezihlola ihlathi zifuna igatsha eliqhephukayo.
