Animal Ears 🪰 Yileyo ndlela izilwane ezizwa ngayo
U-impukane uzwa kanjani?
Aedes aegypti
Ayizwa isekude: izimpondo zayo zizwa umoya onyakaziswa yiphiko eliseceleni.
Ngamafuphi
U-Impukane uzwa cishe kusukela ku-80 Hz kuya ku-800 Hz, futhi ubamba kangcono eduze kuka-380 Hz. Nge-Animal Ears ungathatha noma yimuphi umsindo wakho bese uwuzwa ngendlela ayizwa ngayo.
Izimpukane nomiyane azizwa njengawe: zizwa umoya unyakaza kusukela eduze kakhulu, ngezimpondo ezinezimpaphe ezidlidliza njengezinwele ezincane. Indawo yazo engcono kakhulu icishe ibe ngu-380 Hz, okusho ngqo ukubhonga kwamaphiko ashaya eduze kwazo. Ngaphezu kwamasentimitha ambalwa, umhlaba wazo womsindo uyaphela. (Leli jikelele lisebenzisa umiyane, ocwaningwe kakhulu, njengesikhundleni sesayensi.)
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 | 80 Hz |
|---|---|
| Umsindo ophakeme kakhulu | 800 Hz |
| Umsindo awuzwa kacace kunayo yonke | 380 Hz |
| Okuzwa wena | 20 Hz – 20 kHz |
Izindlebe zakho vs. ezika-Impukane
Ngakolunye uhlangothi uphuthelwa imisindo ephakeme oyizwayo wena: ngaphezu kuka-0.8 kHz, kuye akusekho lutho.
I-audiogram
| I-Hertz (Hz) | Umkhawulo wokuzwa |
|---|---|
| 80 Hz | 35 dB |
| 150 Hz | 20 dB |
| 230 Hz | 10 dB |
| 300 Hz | 5 dB |
| 380 Hz | 2 dB |
| 450 Hz | 6 dB |
| 550 Hz | 15 dB |
| 700 Hz | 28 dB |
| 800 Hz | 38 dB |
A mosquito is used as a documented acoustic proxy (housefly hearing is poorly characterised); near-field flagellar hearing via Johnston's organ, tuned ~380 Hz. Detection-band-derived; dB relative/approximate.
Ingabe u-Impukane uzwa izinto ongenakuzizwa wena?
U-Impukane ubamba konke kusukela ku-80 Hz (ophansi kakhulu) kuya ku-800 Hz (ophakeme kakhulu), futhi uzwa kacace kakhulu eduze kuka-380 Hz.
Ngakolunye uhlangothi uphuthelwa imisindo ephakeme oyizwayo wena: ngaphezu kuka-0.8 kHz, kuye akusekho lutho.
Imibuzo evamile
Yimiphi imisindo ezwiwa ngu-Impukane?

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

Ezinye izilwane
Inyosi
Ayizwa isekude: izwa ukudlidliza komoya ngezimpondo, kusukela kumasentimitha amabili.
Uzekamanzi
Alunazo nhlobo izindlebe: lufunda umoya ngezinwele nezimpondo lundiza.
Ufudu lwasolwandle
Izwa ngaphansi kwamanzi futhi imisindo ephansi kuphela: ephakeme idlula eceleni kwayo.
Ushaka
Imisindo ephansi kuphela emthintayo: inhlanzi elimele ephithizela emamitheni angamakhulu.
