Animal Ears 🦆 Yileyo ndlela izilwane ezizwa ngayo
U-idada uzwa kanjani?
Anas platyrhynchos
Ukuzwa kwenyoni okuvamile: akukho okweqile, konke kusendaweni yokukhala kwedada.
Ngamafuphi
U-Idada uzwa cishe kusukela ku-66 Hz kuya ku-7.6 kHz, futhi ubamba kangcono eduze kuka-2 kHz. Nge-Animal Ears ungathatha noma yimuphi umsindo wakho bese uwuzwa ngendlela ayizwa ngayo.
Idada lasendle lizwa kusukela ku-66 kuya ku-7 600 Hz, kungcono eduze kuka-2 000: ukuzwa kwenyoni okuvamile, ngaphandle kokweqile nganoma yiluphi uhlangothi. Alitholi i-infrasound, ngokungafani nejuba, futhi alifinyeleli emisindweni yakho ephakeme. Amandla alo asemkhakheni ophakathi — umkhakha wokukhala, wokuchithekela kwamanzi nowokushaya kwamaphiko — okusho ngqo lapho impilo yedada yenzeka 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 | 66 Hz |
|---|---|
| Umsindo ophakeme kakhulu | 7.6 kHz |
| Umsindo awuzwa kacace kunayo yonke | 2 kHz |
| Okuzwa wena | 20 Hz – 20 kHz |
Izindlebe zakho vs. ezika-Idada
Ngakolunye uhlangothi uphuthelwa imisindo ephakeme oyizwayo wena: ngaphezu kuka-7.6 kHz, kuye akusekho lutho.
I-audiogram
| I-Hertz (Hz) | Umkhawulo wokuzwa |
|---|---|
| 100 Hz | 52 dB |
| 250 Hz | 38 dB |
| 500 Hz | 25 dB |
| 1 kHz | 15 dB |
| 2 kHz | 9 dB |
| 3 kHz | 11 dB |
| 4 kHz | 18 dB |
| 6 kHz | 38 dB |
| 8 kHz | 55 dB |
In-air behavioural audiogram (dB SPL); best ~2 kHz; digitised approximation of the classic Trainer (1946) curve compiled in Fay (1988). A 2017 mallard audiogram (doi:10.1007/s00359-017-1204-6) reports 66 Hz–7.6 kHz; mallards do not detect infrasound.
Ingabe u-Idada uzwa izinto ongenakuzizwa wena?
U-Idada ubamba konke kusukela ku-66 Hz (ophansi kakhulu) kuya ku-7.6 kHz (ophakeme kakhulu), futhi uzwa kacace kakhulu eduze kuka-2 kHz.
Ngakolunye uhlangothi uphuthelwa imisindo ephakeme oyizwayo wena: ngaphezu kuka-7.6 kHz, kuye akusekho lutho.
Imibuzo evamile
Yimiphi imisindo ezwiwa ngu-Idada?
U-Idada ubamba konke kusukela ku-66 Hz (ophansi kakhulu) kuya ku-7.6 kHz (ophakeme kakhulu), futhi uzwa kacace kakhulu eduze kuka-2 kHz.
Ingabe u-Idada uzwa izinto ongenakuzizwa wena?

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

Ezinye izilwane
Inkukhu
Iphuthelwa imisindo yakho ephakeme, kodwa yehlela ekudumeni ongakuthinti nhlobo.
I-hummingbird
Ihlabelela amanothi aphakeme kunalawo ekwazi ukuwezwa.
I-penguin
Ithola iphathina yayo ngezwi phakathi kwezinkulungwane zamaphengwini amemeza ngasikhathi sinye.
Ukhozi
Ukubona kwezinga eliphezulu, ukuzwa okuvamile: ibamba imisindo ephakeme kancane kunawe.
