🐘 Yileyo ndlela izilwane ezizwa ngayo

U-indlovu uzwa kanjani?

Elephas maximus

Ikhuluma ngokuduma okuphansi kangangokuthi kuhamba amakhilomitha futhi wena ucishe ungakuzwa.

Ngamafuphi

U-Indlovu uzwa cishe kusukela ku-17 Hz kuya ku-10.5 kHz, futhi ubamba kangcono eduze kuka-1 kHz. Nge-Animal Ears ungathatha noma yimuphi umsindo wakho bese uwuzwa ngendlela ayizwa ngayo.

Indlovu ibheka phansi, hhayi phezulu: yehla kuze kube ngu-17 Hz, ngaphansi kwakho, kanti ngakolunye uhlangothi ayidluli ku-10 500 Hz, uhhafu wophahla lwakho. Lokho kuduma okuphansi kakhulu kuyi-infrasound futhi kunenzuzo enkulu: kuhamba kude kakhulu kungehli amandla, ngakho imihlambi emibili ingakwazi “ukukhuluma” isuka emakhilomitheni. Futhi azilaleli ngezindlebe kuphela: zibamba ukudlidliza nangezinyawo nangomboko, ngqo emhlabathini.

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.

Indlovu17 Hz – 10.5 kHz

Uzwa kacace kakhulu ku-1 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.

Izindlebe zakho vs. ezika-Indlovu

Yebo: ubamba ukuduma okuphansi kangangokuthi wena ungakuzwa esifubeni kuphela, kuze kube cishe 17 Hz. Phansi kwakho kungu-20 Hz. Ngakolunye uhlangothi uphuthelwa imisindo ephakeme oyizwayo wena: ngaphezu kuka-10.5 kHz, kuye akusekho lutho.

Ingabe u-Indlovu uzwa izinto ongenakuzizwa wena?

🐘 Indlovu

U-Indlovu ubamba konke kusukela ku-17 Hz (ophansi kakhulu) kuya ku-10.5 kHz (ophakeme kakhulu), futhi uzwa kacace kakhulu eduze kuka-1 kHz.

👤 Okuzwa wena

Imibuzo evamile

Yimiphi imisindo ezwiwa ngu-Indlovu?

U-Indlovu ubamba konke kusukela ku-17 Hz (ophansi kakhulu) kuya ku-10.5 kHz (ophakeme kakhulu), futhi uzwa kacace kakhulu eduze kuka-1 kHz.

Ingabe u-Indlovu uzwa izinto ongenakuzizwa wena?

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

Ososayensi balinganisile, izinga ngezinga, ukuthi umsindo kufanele ube mkhulu kangakanani ukuze u-Indlovu 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-infrasound

Imisindo ephansi kangangokuthi indlebe yakho ayisayibhali: ngaphansi kuka-20 Hz. Esikhundleni sokuyizwa, ungezwa ukudlidliza esifubeni, njengalapho kudlula iloli elisindayo. Izindlovu namajuba kona ziyayibamba, ngisho namakhilomitha kude.
