Animal Ears 🦐 Yileyo ndlela izilwane ezizwa ngayo
U-i-mantis shrimp uzwa kanjani?
Hemisquilla californiensis
Ibhonga phansi olwandle ngokuduma okuphansi; indlela ekuzwa ngayo isengumfihlakalo.
Ngamafuphi
U-I-mantis shrimp uzwa cishe kusukela ku-20 Hz kuya ku-1 kHz, futhi ubamba kangcono eduze kuka-40 Hz. Nge-Animal Ears ungathatha noma yimuphi umsindo wakho bese uwuzwa ngendlela ayizwa ngayo.
I-mantis shrimp ikhipha ukubhonga okuphansi nokunanelayo ngaphansi kwamanzi, ikakhulukazi ekuseni nakusihlwa. Uma ikukhiqiza, kungenzeka kakhulu ukuthi iyakubamba futhi, mhlawumbe ngokuzwa ukunyakaza kwamanzi kunengcindezi, emkhakheni ophansi kakhulu kusukela ku-20 kuya ku-1 000 Hz. Kodwa asisho ngokusobala: akekho oseke walinganisa ukuzwa kwayo ngokunembile, ngakho leli jikelele lithathwe emisindweni ekhiqizwa yiyona ngokwayo.
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 | 20 Hz |
|---|---|
| Umsindo ophakeme kakhulu | 1 kHz |
| Umsindo awuzwa kacace kunayo yonke | 40 Hz |
| Okuzwa wena | 20 Hz – 20 kHz |
Izindlebe zakho vs. ezika-I-mantis shrimp
Ngakolunye uhlangothi uphuthelwa imisindo ephakeme oyizwayo wena: ngaphezu kuka-1 kHz, kuye akusekho lutho.
I-audiogram
| I-Hertz (Hz) | Umkhawulo wokuzwa |
|---|---|
| 20 Hz | 8 dB |
| 40 Hz | 4 dB |
| 60 Hz | 5 dB |
| 100 Hz | 10 dB |
| 200 Hz | 18 dB |
| 400 Hz | 28 dB |
| 700 Hz | 38 dB |
| 1 kHz | 45 dB |
Underwater: produces low-frequency rumbles (~20–60 Hz) and likely detects the particle-motion component of sound. Detection organ unresolved; curve derived from the sound-production spectrum, relative units — not a measured audiogram.
Ingabe u-I-mantis shrimp uzwa izinto ongenakuzizwa wena?
U-I-mantis shrimp ubamba konke kusukela ku-20 Hz (ophansi kakhulu) kuya ku-1 kHz (ophakeme kakhulu), futhi uzwa kacace kakhulu eduze kuka-40 Hz.
Ngakolunye uhlangothi uphuthelwa imisindo ephakeme oyizwayo wena: ngaphezu kuka-1 kHz, kuye akusekho lutho.
Imibuzo evamile
Yimiphi imisindo ezwiwa ngu-I-mantis shrimp?

I-Animal Ears yenza kanjani ukuthi umsindo uzwakale njengoba u-I-mantis shrimp ewuzwa?
Ososayensi balinganisile, izinga ngezinga, ukuthi umsindo kufanele ube mkhulu kangakanani ukuze u-I-mantis shrimp 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
I-clownfish
Amaphuphu ayo afuna ukuqhephuka kwehlanga lwezinhlobo zolwandle ukuze athole ikhaya.
I-dragonfish
Umlaleli wasekujuleni: sazi kancane kakhulu kangangokuthi lokhu kungumcabango oqotho.
Inyoka
Ngaphandle kwesikhumba sendlebe nezindlebe: izwa izinyathelo zakho ngomhlathi phansi.
Uzekamanzi
Alunazo nhlobo izindlebe: lufunda umoya ngezinwele nezimpondo lundiza.
