Animal Ears 🦝 Yileyo ndlela izilwane ezizwa ngayo
U-i-raccoon uzwa kanjani?
Procyon lotor
Ibanga layo elibanzi lomoya lifinyelela ku-40,000 Hz, kuyilapho iphuzu layo elilinganiselwe elibucayi lihlala eduze kuka-1,000 Hz.
Ngamafuphi
U-I-raccoon uzwa cishe kusukela ku-100 Hz kuya ku-40 kHz, futhi ubamba kangcono eduze kuka-1 kHz. Nge-Animal Ears ungathatha noma yimuphi umsindo wakho bese uwuzwa ngendlela ayizwa ngayo.
I-raccoon izwa amathoni asemoyeni kusukela ku-100 kuya ku-40,000 Hz kumbandela wocwaningo we-60 dB, cishe kabili kunophahla oluvamile lomuntu lwe-high-frequency. Umkhawulo wayo okalwe ophansi useduze no-1,000 Hz - eduze kwamanothi aphezulu upiyano - kuyilapho ijika elishicilelwe linesinye isifunda esibucayi eduze no-8,000 Hz. Lokhu kuvela esifundweni sokuziphatha esimsulwa; I-Animal Ears ishintsha ukuma okuhlobene kwejika ku-EQ, hhayi ikhophi yangempela yalokho okutholwa i-raccoon.
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 | 100 Hz |
|---|---|
| Umsindo ophakeme kakhulu | 40 kHz |
| Umsindo awuzwa kacace kunayo yonke | 1 kHz |
| Okuzwa wena | 20 Hz – 20 kHz |
Izindlebe zakho vs. ezika-I-raccoon
Yebo: ubamba imisindo ephakeme kangangokuthi kuwe kuwukuthula okuphelele, kuze kube cishe 40 kHz. Uphahla lwakho lungu-20 kHz.
I-audiogram
| I-Hertz (Hz) | Umkhawulo wokuzwa |
|---|---|
| 100 Hz | 28 dB |
| 200 Hz | 16 dB |
| 500 Hz | 1 dB |
| 1 kHz | -12 dB |
| 2 kHz | -10 dB |
| 4 kHz | -5 dB |
| 8 kHz | -10 dB |
| 16 kHz | 0 dB |
| 20 kHz | 10 dB |
| 32 kHz | 0 dB |
| 40 kHz | 30 dB |
| 50 kHz | 80 dB |
In-air behavioural pure-tone audiogram, dB SPL re 20 µPa. Rounded digitisation of Wollack (1965) as reproduced by Ghoul & Reichmuth (2014): ~100 Hz–40 kHz at the 60 dB criterion, with the lowest measured threshold near 1 kHz. The relative EQ models only threshold-curve shape; it is not a literal reconstruction of raccoon hearing.
Ingabe u-I-raccoon uzwa izinto ongenakuzizwa wena?
U-I-raccoon ubamba konke kusukela ku-100 Hz (ophansi kakhulu) kuya ku-40 kHz (ophakeme kakhulu), futhi uzwa kacace kakhulu eduze kuka-1 kHz.
Yebo: ubamba imisindo ephakeme kangangokuthi kuwe kuwukuthula okuphelele, kuze kube cishe 40 kHz. Uphahla lwakho lungu-20 kHz.
Imibuzo evamile
Yimiphi imisindo ezwiwa ngu-I-raccoon?

I-Animal Ears yenza kanjani ukuthi umsindo uzwakale njengoba u-I-raccoon ewuzwa?
Ososayensi balinganisile, izinga ngezinga, ukuthi umsindo kufanele ube mkhulu kangakanani ukuze u-I-raccoon 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-ultrasound
Imisindo ephakeme kangangokuthi indlebe yakho ayisayibhali: ngaphezu kuka-20 000 Hz. Kuwe kuwukuthula okuphelele, kodwa inja, ikati noma ilulwane bayayizwa kahle. Impempe yezinja “ethule” ikhona lapho.

Ezinye izilwane
Unogwaja
Izindlebe zayo ziyimigqumo emikhulu: ziqoqa ingozi ingakabonwa nhlobo.
Imbuzi
Izwa i-ultrasound, kodwa ibukhali kakhulu ezingeni ngqo lokukhala kwayo.
Ihhashi
Izindlebe eziphenduka 180° ngayinye: izwa ngemuva kwayo ingashukumi.
Indlovu
Ikhuluma ngokuduma okuphansi kangangokuthi kuhamba amakhilomitha futhi wena ucishe ungakuzwa.
