🐑 Yileyo ndlela izilwane ezizwa ngayo

U-imvu uzwa kanjani?

Ovis aries

Ububanzi obukhulu kuze kube yi-ultrasound nendlebe emnene ebona ukuthi ngubani okhalayo.

Ngamafuphi

U-Imvu uzwa cishe kusukela ku-100 Hz kuya ku-30 kHz, futhi ubamba kangcono eduze kuka-7 kHz. Nge-Animal Ears ungathatha noma yimuphi umsindo wakho bese uwuzwa ngendlela ayizwa ngayo.

Imvu izwa kusukela ku-100 kuya ku-30 000 Hz, ngakho uphahla lwayo lungena kahle ku-ultrasound ongafinyeleli kuyo. Ibukhali kakhulu phakathi kuka-7 000 no-10 000 Hz, ngaphezu kwakho. Emhlambini lokho kuwusizo olukhulu: ukukhala ngakunye kuthwele imininingwane eminingi emazingeni aphezulu, futhi yilapho ngqo okukhona khona “isayina” elihlukanisa esinye isilwane kwesinye. Thina sizwa “mbeee”; zona zizwa ukuthi ngubani.

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

Imvu100 Hz – 30 kHz

Uzwa kacace kakhulu ku-7 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: Imvu
Umsindo ophansi kakhulu	100 Hz
Umsindo ophakeme kakhulu	30 kHz
Umsindo awuzwa kacace kunayo yonke	7 kHz
Okuzwa wena	20 Hz – 20 kHz

Izindlebe zakho vs. ezika-Imvu

Yebo: ubamba imisindo ephakeme kangangokuthi kuwe kuwukuthula okuphelele, kuze kube cishe 30 kHz. Uphahla lwakho lungu-20 kHz.

Ingabe u-Imvu uzwa izinto ongenakuzizwa wena?

🐑 Imvu

U-Imvu ubamba konke kusukela ku-100 Hz (ophansi kakhulu) kuya ku-30 kHz (ophakeme kakhulu), futhi uzwa kacace kakhulu eduze kuka-7 kHz.

👤 Okuzwa wena

Yebo: ubamba imisindo ephakeme kangangokuthi kuwe kuwukuthula okuphelele, kuze kube cishe 30 kHz. Uphahla lwakho lungu-20 kHz.

Imibuzo evamile

Yimiphi imisindo ezwiwa ngu-Imvu?

U-Imvu ubamba konke kusukela ku-100 Hz (ophansi kakhulu) kuya ku-30 kHz (ophakeme kakhulu), futhi uzwa kacace kakhulu eduze kuka-7 kHz.

Ingabe u-Imvu uzwa izinto ongenakuzizwa wena?

Yebo: ubamba imisindo ephakeme kangangokuthi kuwe kuwukuthula okuphelele, kuze kube cishe 30 kHz. Uphahla lwakho lungu-20 kHz.

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

Ososayensi balinganisile, izinga ngezinga, ukuthi umsindo kufanele ube mkhulu kangakanani ukuze u-Imvu 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.
