Animal Ears 🕷️ Yileyo ndlela izilwane ezizwa ngayo
U-isicabucabu esiqhwakelayo uzwa kanjani?
Phidippus audax
Ngaphandle kwezindlebe, kodwa izwa umnyovu ngale kwekamelo... ngemilenze yayo.
Ngamafuphi
U-Isicabucabu esiqhwakelayo uzwa cishe kusukela ku-80 Hz kuya ku-2 kHz, futhi ubamba kangcono eduze kuka-100 Hz. Nge-Animal Ears ungathatha noma yimuphi umsindo wakho bese uwuzwa ngendlela ayizwa ngayo.
Iminyaka kwakukholelwa ukuthi izicabucabu eziqhoshayo zizwa ukudlidliza ngokuthinta kuphela. Kwabe sekutholakala ukuthi zima nse lapho zizwa umsindo ofika ngomoya, ukusuka emamitheni ambalwa. Zizwa ngezinwele ezincane kakhulu emilenzeni, ezinyakaza nomoya. Indawo yazo engcono kakhulu ngu-100 Hz... okuyinto ngokwenhlanhla eyona ngqo ukubhonga kwamaphiko eminyovu ezihlaselayo.
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 | 2 kHz |
| Umsindo awuzwa kacace kunayo yonke | 100 Hz |
| Okuzwa wena | 20 Hz – 20 kHz |
Izindlebe zakho vs. ezika-Isicabucabu esiqhwakelayo
Ngakolunye uhlangothi uphuthelwa imisindo ephakeme oyizwayo wena: ngaphezu kuka-2 kHz, kuye akusekho lutho.
I-audiogram
| I-Hertz (Hz) | Umkhawulo wokuzwa |
|---|---|
| 80 Hz | 65 dB |
| 100 Hz | 63 dB |
| 130 Hz | 65 dB |
| 200 Hz | 70 dB |
| 300 Hz | 76 dB |
| 380 Hz | 80 dB |
| 500 Hz | 86 dB |
| 1 kHz | 92 dB |
| 2 kHz | 98 dB |
Detects far-field airborne sound via air-movement-sensitive leg hairs, strongest at low frequencies ~80–380 Hz (startle to ~80 Hz), likely matching predatory-wasp wingbeats. Detection-band-derived; high-frequency thresholds are extrapolated.
Ingabe u-Isicabucabu esiqhwakelayo uzwa izinto ongenakuzizwa wena?
U-Isicabucabu esiqhwakelayo ubamba konke kusukela ku-80 Hz (ophansi kakhulu) kuya ku-2 kHz (ophakeme kakhulu), futhi uzwa kacace kakhulu eduze kuka-100 Hz.
Ngakolunye uhlangothi uphuthelwa imisindo ephakeme oyizwayo wena: ngaphezu kuka-2 kHz, kuye akusekho lutho.
Imibuzo evamile
Yimiphi imisindo ezwiwa ngu-Isicabucabu esiqhwakelayo?
U-Isicabucabu esiqhwakelayo ubamba konke kusukela ku-80 Hz (ophansi kakhulu) kuya ku-2 kHz (ophakeme kakhulu), futhi uzwa kacace kakhulu eduze kuka-100 Hz.

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

Indlebe ehlukaniswe kabili, ilungiselelwe amanothi amabili engoma yayo.
Inyoka
Ngaphandle kwesikhumba sendlebe nezindlebe: izwa izinyathelo zakho ngomhlathi phansi.
