Animal Ears 🐬 Yileyo ndlela izilwane ezizwa ngayo
U-ihlengethwa uzwa kanjani?
Tursiops truncatus
Ukhuphuka izikhathi eziyisikhombisa ngaphezu kwakho futhi “ubona” ngaphansi kwamanzi nge-echo yamaklikhi akhe.
Ngamafuphi
U-Ihlengethwa uzwa cishe kusukela ku-75 Hz kuya ku-150 kHz, futhi ubamba kangcono eduze kuka-60 kHz. Nge-Animal Ears ungathatha noma yimuphi umsindo wakho bese uwuzwa ngendlela ayizwa ngayo.
Ihlengethwa lifinyelela ku-150 000 Hz, cishe izikhathi eziyisikhombisa zophahla lwakho, futhi lizwa kangcono eduze kuka-60 000 Hz: indawo engekho nhlobo kuwe. Yilapho amaklikhi alo aphila khona. Likhipha amaklikhi asheshayo kakhulu bese lilalela i-echo ebuyayo, kanti kuyona lakha isithombe salokho okuphambi kwalo: isimo, ibanga, ngisho nokuthi inhlanzi inokuthile yini ngaphakathi. Emanzini adungekile, lapho ukubona kungasizi, “libona” ngezindlebe.
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 | 75 Hz |
|---|---|
| Umsindo ophakeme kakhulu | 150 kHz |
| Umsindo awuzwa kacace kunayo yonke | 60 kHz |
| Okuzwa wena | 20 Hz – 20 kHz |
Izindlebe zakho vs. ezika-Ihlengethwa
Yebo: ubamba imisindo ephakeme kangangokuthi kuwe kuwukuthula okuphelele, kuze kube cishe 150 kHz. Uphahla lwakho lungu-20 kHz.

| 100 Hz | 128 dB |
| 1 kHz | 98 dB |
| 5 kHz | 70 dB |
| 10 kHz | 57 dB |
| 20 kHz | 52 dB |
| 30 kHz | 48 dB |
| 50 kHz | 44 dB |
| 60 kHz | 43 dB |
| 75 kHz | 45 dB |
| 100 kHz | 56 dB |
| 120 kHz | 75 dB |
| 150 kHz | 120 dB |
UNDERWATER audiogram in dB re 1 µPa — not comparable to in-air dB SPL. EQ uses the curve shape (relative to the dolphin's own best band). Best plateau ~40–80 kHz.
Ingabe u-Ihlengethwa uzwa izinto ongenakuzizwa wena?
U-Ihlengethwa ubamba konke kusukela ku-75 Hz (ophansi kakhulu) kuya ku-150 kHz (ophakeme kakhulu), futhi uzwa kacace kakhulu eduze kuka-60 kHz.
Yebo: ubamba imisindo ephakeme kangangokuthi kuwe kuwukuthula okuphelele, kuze kube cishe 150 kHz. Uphahla lwakho lungu-20 kHz.
Imibuzo evamile
Yimiphi imisindo ezwiwa ngu-Ihlengethwa?
U-Ihlengethwa ubamba konke kusukela ku-75 Hz (ophansi kakhulu) kuya ku-150 kHz (ophakeme kakhulu), futhi uzwa kacace kakhulu eduze kuka-60 kHz.
Ingabe u-Ihlengethwa uzwa izinto ongenakuzizwa wena?

I-Animal Ears yenza kanjani ukuthi umsindo uzwakale njengoba u-Ihlengethwa ewuzwa?
Ososayensi balinganisile, izinga ngezinga, ukuthi umsindo kufanele ube mkhulu kangakanani ukuze u-Ihlengethwa 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-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.
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
Ibhu
Indlebe enomsebenzi owodwa kuphela: ukuthola ilulwane kungakabi sephuzu.
Ilulwane
Lizingela ebumnyameni lifunda i-echo yokukhala kwalo, izikhathi ezinhlanu ngaphezu kophahla lwakho.
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.
