Animal Ears 🕊️ Yileyo ndlela izilwane ezizwa ngayo
U-ijuba uzwa kanjani?
Columba livia
Amandla alo amakhulu angaphansi kokuzwa kwakho: libamba ukuduma kweziphepho ezikude.
Ngamafuphi
U-Ijuba uzwa cishe kusukela ku-40 Hz kuya ku-8.5 kHz, futhi ubamba kangcono eduze kuka-1 kHz. Nge-Animal Ears ungathatha noma yimuphi umsindo wakho bese uwuzwa ngendlela ayizwa ngayo.
Ebubanzini obuvamile, ijuba lizwa kabi kunawe: kusukela ku-40 kuya ku-8 500 Hz, ngakho liphuthelwa yonke imisindo ephakeme yakho. Ikhono lalo lisemgodini ongaphansi. Lithola i-infrasound ephansi ngendlela emangalisayo, phansi kakhulu komkhawulo wakho, okusho ukuduma kwangasemuva komhlaba: iziphepho ezingamakhilomitha amakhulu kude, amagagasi aqhephuka ogwini, umoya odabula uhla lwezintaba. Kucatshangwa ukuthi leyo “mephu yomsindo” iyalisiza ukuthola indlela yokugoduka.
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 | 40 Hz |
|---|---|
| Umsindo ophakeme kakhulu | 8.5 kHz |
| Umsindo awuzwa kacace kunayo yonke | 1 kHz |
| Okuzwa wena | 20 Hz – 20 kHz |
Izindlebe zakho vs. ezika-Ijuba
Ngakolunye uhlangothi uphuthelwa imisindo ephakeme oyizwayo wena: ngaphezu kuka-8.5 kHz, kuye akusekho lutho.
I-audiogram
| I-Hertz (Hz) | Umkhawulo wokuzwa |
|---|---|
| 10 Hz | 50 dB |
| 50 Hz | 35 dB |
| 100 Hz | 28 dB |
| 250 Hz | 18 dB |
| 500 Hz | 9 dB |
| 1 kHz | 3 dB |
| 2 kHz | 6 dB |
| 4 kHz | 22 dB |
| 6 kHz | 36 dB |
| 8 kHz | 50 dB |
Best ~1–2 kHz; pigeons are exceptionally sensitive to infrasound (documented to ~0.05 Hz), so the modelled low-frequency floor is a conservative behavioural approximation.
Ingabe u-Ijuba uzwa izinto ongenakuzizwa wena?
U-Ijuba ubamba konke kusukela ku-40 Hz (ophansi kakhulu) kuya ku-8.5 kHz (ophakeme kakhulu), futhi uzwa kacace kakhulu eduze kuka-1 kHz.
Ngakolunye uhlangothi uphuthelwa imisindo ephakeme oyizwayo wena: ngaphezu kuka-8.5 kHz, kuye akusekho lutho.
Imibuzo evamile
Yimiphi imisindo ezwiwa ngu-Ijuba?

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

Ukuzwa kwenyoni okuvamile: akukho okweqile, konke kusendaweni yokukhala kwedada.
I-penguin
Ithola iphathina yayo ngezwi phakathi kwezinkulungwane zamaphengwini amemeza ngasikhathi sinye.
Inkukhu
Iphuthelwa imisindo yakho ephakeme, kodwa yehlela ekudumeni ongakuthinti nhlobo.
I-hummingbird
Ihlabelela amanothi aphakeme kunalawo ekwazi ukuwezwa.
