Animal Ears 🦉 Yileyo ndlela izilwane ezizwa ngayo
U-isikhova uzwa kanjani?
Tyto alba
Izingela igundane ebumnyameni obuphelele ngezindlebe kuphela, ingaphuthi.
Ngamafuphi
U-Isikhova uzwa cishe kusukela ku-200 Hz kuya ku-12 kHz, futhi ubamba kangcono eduze kuka-6.3 kHz. Nge-Animal Ears ungathatha noma yimuphi umsindo wakho bese uwuzwa ngendlela ayizwa ngayo.
Isikhova sasenqolobaneni asinabo ububanzi obumangalisayo (kusukela ku-200 kuya ku-12 000 Hz), kodwa ukunemba kwaso kuyethusa. Izindlebe zaso zombili zimi emazingeni ahlukene, enye ingenhla kancane kunenye, ngakho umsindo owodwa ufinyelela kuleyo naleyo ngomehluko omncane kakhulu. Ubuchopho baso buhlanganisa lolo lwazi bubale iphuzu ngqo: phezulu, phansi, kwesobunxele, kwesokudla. Singazingela igundane ebumnyameni obuphelele siholwa kuphela umsindo omncane elenzayo lapho linyakaza.
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 | 200 Hz |
|---|---|
| Umsindo ophakeme kakhulu | 12 kHz |
| Umsindo awuzwa kacace kunayo yonke | 6.3 kHz |
| Okuzwa wena | 20 Hz – 20 kHz |
Izindlebe zakho vs. ezika-Isikhova
Ngakolunye uhlangothi uphuthelwa imisindo ephakeme oyizwayo wena: ngaphezu kuka-12 kHz, kuye akusekho lutho.
I-audiogram
| I-Hertz (Hz) | Umkhawulo wokuzwa |
|---|---|
| 100 Hz | 55 dB |
| 250 Hz | 32 dB |
| 500 Hz | 18 dB |
| 1 kHz | 6 dB |
| 2 kHz | -2 dB |
| 3 kHz | -9 dB |
| 4 kHz | -12 dB |
| 6.3 kHz | -14 dB |
| 8 kHz | -10 dB |
| 10 kHz | 12 dB |
| 12 kHz | 40 dB |
Behavioural audiogram; the barn owl ear is among the most sensitive of any vertebrate (~-14 dB near 6 kHz). Asymmetric ears give localisation, not extra bandwidth.
Ingabe u-Isikhova uzwa izinto ongenakuzizwa wena?
U-Isikhova ubamba konke kusukela ku-200 Hz (ophansi kakhulu) kuya ku-12 kHz (ophakeme kakhulu), futhi uzwa kacace kakhulu eduze kuka-6.3 kHz.
Ngakolunye uhlangothi uphuthelwa imisindo ephakeme oyizwayo wena: ngaphezu kuka-12 kHz, kuye akusekho lutho.
Imibuzo evamile
Yimiphi imisindo ezwiwa ngu-Isikhova?

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