🐕 Yileyo ndlela izilwane ezizwa ngayo

U-inja uzwa kanjani?

Canis familiaris

Uzwa ukukhala okuwukuthula kuwe: yingakho izimpempe “ezithule” zisebenza.

Ngamafuphi

U-Inja uzwa cishe kusukela ku-67 Hz kuya ku-45 kHz, futhi ubamba kangcono eduze kuka-4 kHz. Nge-Animal Ears ungathatha noma yimuphi umsindo wakho bese uwuzwa ngendlela ayizwa ngayo.

Emazingeni aphakathi, inja izwa cishe njengawe. Umehluko usesitezi esiphezulu: ifinyelela cishe ku-45 000 Hz, ngaphezu kokuphindwe kabili kophahla lwakho. Sonke leso sigaba yi-ultrasound futhi kuwe kuwukuthula: ukukhala kwethoyi, ukukhenceza kwephleti entanyeni, igundane eliklwebha ngaphakathi odongeni. Ngaphezu kwalokho ibukhali kakhulu eduze kuka-4 000 Hz, indawo yemilozi ephakeme... neyezwi lakho lapho ukhuluma nayo ngalelo zwi eliphakeme lokudlala eliyithanda kangaka.

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.

🌩️ 🐘20 Hz

🗣️ 🎹3 kHz

🐭 🦇20+ kHz

Inja67 Hz – 45 kHz

Uzwa kacace kakhulu ku-4 kHz

Okuzwa wena20 Hz – 20 kHz

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.

Izinombolo ezibalulekile: Inja
Umsindo ophansi kakhulu	67 Hz
Umsindo ophakeme kakhulu	45 kHz
Umsindo awuzwa kacace kunayo yonke	4 kHz
Okuzwa wena	20 Hz – 20 kHz

Izindlebe zakho vs. ezika-Inja

Yebo: ubamba imisindo ephakeme kangangokuthi kuwe kuwukuthula okuphelele, kuze kube cishe 45 kHz. Uphahla lwakho lungu-20 kHz.

Ingabe u-Inja uzwa izinto ongenakuzizwa wena?

🐕 Inja

U-Inja ubamba konke kusukela ku-67 Hz (ophansi kakhulu) kuya ku-45 kHz (ophakeme kakhulu), futhi uzwa kacace kakhulu eduze kuka-4 kHz.

👤 Okuzwa wena

Yebo: ubamba imisindo ephakeme kangangokuthi kuwe kuwukuthula okuphelele, kuze kube cishe 45 kHz. Uphahla lwakho lungu-20 kHz.

Imibuzo evamile

Yimiphi imisindo ezwiwa ngu-Inja?

U-Inja ubamba konke kusukela ku-67 Hz (ophansi kakhulu) kuya ku-45 kHz (ophakeme kakhulu), futhi uzwa kacace kakhulu eduze kuka-4 kHz.

Ingabe u-Inja uzwa izinto ongenakuzizwa wena?

Yebo: ubamba imisindo ephakeme kangangokuthi kuwe kuwukuthula okuphelele, kuze kube cishe 45 kHz. Uphahla lwakho lungu-20 kHz.

I-Animal Ears yenza kanjani ukuthi umsindo uzwakale njengoba u-Inja ewuzwa?

Ososayensi balinganisile, izinga ngezinga, ukuthi umsindo kufanele ube mkhulu kangakanani ukuze u-Inja 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-Hertz (Hz)

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.
