Animal Ears 🐧 Yileyo ndlela izilwane ezizwa ngayo
U-i-penguin uzwa kanjani?
Spheniscus humboldti
Ithola iphathina yayo ngezwi phakathi kwezinkulungwane zamaphengwini amemeza ngasikhathi sinye.
Ngamafuphi
U-I-penguin uzwa cishe kusukela ku-250 Hz kuya ku-10 kHz, futhi ubamba kangcono eduze kuka-2 kHz. Nge-Animal Ears ungathatha noma yimuphi umsindo wakho bese uwuzwa ngendlela ayizwa ngayo.
Iphengwini lase-Humboldt lizwa emoyeni kusukela ku-250 kuya ku-10 000 Hz, kungcono eduze kuka-2 000 Hz. Inselelo yempilo yalo yile: ukubuya olwandle liye ekoloni enezinkulungwane zezidalwa ezicishe zifane, zonke zimemeza ngasikhathi sinye, bese lifuna iphathina nechwane lalo. Lisombulula lokhu ngezwi: ukumemeza ngakunye kunesayina lakho, futhi ukuzwa kwalo kulungiselelwe ngqo umkhakha lapho lelo sayina liphila khona.
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 | 250 Hz |
|---|---|
| Umsindo ophakeme kakhulu | 10 kHz |
| Umsindo awuzwa kacace kunayo yonke | 2 kHz |
| Okuzwa wena | 20 Hz – 20 kHz |
Izindlebe zakho vs. ezika-I-penguin
Ngakolunye uhlangothi uphuthelwa imisindo ephakeme oyizwayo wena: ngaphezu kuka-10 kHz, kuye akusekho lutho.
I-audiogram
| I-Hertz (Hz) | Umkhawulo wokuzwa |
|---|---|
| 250 Hz | 37 dB |
| 500 Hz | 64 dB |
| 1 kHz | 48 dB |
| 2 kHz | 15 dB |
| 3 kHz | 20 dB |
| 4 kHz | 18 dB |
| 6 kHz | 28 dB |
| 8 kHz | 35 dB |
| 10 kHz | 50 dB |
In-air behavioural audiogram (dB re 20 µPa), best ~15 dB at 2 kHz; the published dip at 500 Hz is flagged by the authors as possibly methodological. (Wever et al. 1969 concerns the congeneric black-footed penguin.)
Ingabe u-I-penguin uzwa izinto ongenakuzizwa wena?
U-I-penguin ubamba konke kusukela ku-250 Hz (ophansi kakhulu) kuya ku-10 kHz (ophakeme kakhulu), futhi uzwa kacace kakhulu eduze kuka-2 kHz.
Ngakolunye uhlangothi uphuthelwa imisindo ephakeme oyizwayo wena: ngaphezu kuka-10 kHz, kuye akusekho lutho.
Imibuzo evamile
Yimiphi imisindo ezwiwa ngu-I-penguin?
U-I-penguin ubamba konke kusukela ku-250 Hz (ophansi kakhulu) kuya ku-10 kHz (ophakeme kakhulu), futhi uzwa kacace kakhulu eduze kuka-2 kHz.

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

Iphuthelwa imisindo yakho ephakeme, kodwa yehlela ekudumeni ongakuthinti nhlobo.
I-hummingbird
Ihlabelela amanothi aphakeme kunalawo ekwazi ukuwezwa.
Ukhozi
Ukubona kwezinga eliphezulu, ukuzwa okuvamile: ibamba imisindo ephakeme kancane kunawe.
