Animal Ears 🦭 Yileyo ndlela izilwane ezizwa ngayo
U-imvu yamanzi uzwa kanjani?
Phoca vitulina
Ukuzwa okubili kokukodwa: okunye kulungiselelwe umoya, okunye amanzi.
Ngamafuphi
U-Imvu yamanzi uzwa cishe kusukela ku-50 Hz kuya ku-30 kHz, futhi ubamba kangcono eduze kuka-3.2 kHz. Nge-Animal Ears ungathatha noma yimuphi umsindo wakho bese uwuzwa ngendlela ayizwa ngayo.
Imvubu yasolwandle evamile iphila phakathi kwemhlaba emibili futhi izwa kahle kuyo yomibili, into eyivelakancane kakhulu. Emoyeni ifaka kusukela ku-50 kuya ku-30 000 Hz — ngakho nayo ingena ku-ultrasound — futhi ibukhali kakhulu eduze kuka-3 200 Hz, cishe lapho nawe ubukhali khona. Ngaphansi kwamanzi izindlebe zayo zisebenza esikalini esehluke nya. Lokho okubona lapha ukuzwa kwayo emoyeni, okuyikho okungaqhathaniswa nokwakho.
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 | 50 Hz |
|---|---|
| Umsindo ophakeme kakhulu | 30 kHz |
| Umsindo awuzwa kacace kunayo yonke | 3.2 kHz |
| Okuzwa wena | 20 Hz – 20 kHz |
Izindlebe zakho vs. ezika-Imvu yamanzi
Yebo: ubamba imisindo ephakeme kangangokuthi kuwe kuwukuthula okuphelele, kuze kube cishe 30 kHz. Uphahla lwakho lungu-20 kHz.
I-audiogram
| I-Hertz (Hz) | Umkhawulo wokuzwa |
|---|---|
| 100 Hz | 34 dB |
| 250 Hz | 22 dB |
| 500 Hz | 12 dB |
| 1 kHz | 2 dB |
| 2 kHz | -6 dB |
| 3.2 kHz | -13 dB |
| 6.4 kHz | -8 dB |
| 12.8 kHz | 4 dB |
| 16 kHz | 16 dB |
| 22 kHz | 32 dB |
| 30 kHz | 55 dB |
IN-AIR behavioural audiogram (dB re 20 µPa) — distinct from the seal's underwater audiogram (re 1 µPa). Best ~-13 dB near 3.2 kHz; 60 dB SPL criterion.
Ingabe u-Imvu yamanzi uzwa izinto ongenakuzizwa wena?
U-Imvu yamanzi ubamba konke kusukela ku-50 Hz (ophansi kakhulu) kuya ku-30 kHz (ophakeme kakhulu), futhi uzwa kacace kakhulu eduze kuka-3.2 kHz.
Yebo: ubamba imisindo ephakeme kangangokuthi kuwe kuwukuthula okuphelele, kuze kube cishe 30 kHz. Uphahla lwakho lungu-20 kHz.
Imibuzo evamile
Yimiphi imisindo ezwiwa ngu-Imvu yamanzi?
U-Imvu yamanzi ubamba konke kusukela ku-50 Hz (ophansi kakhulu) kuya ku-30 kHz (ophakeme kakhulu), futhi uzwa kacace kakhulu eduze kuka-3.2 kHz.
Ingabe u-Imvu yamanzi uzwa izinto ongenakuzizwa wena?
Yebo: ubamba imisindo ephakeme kangangokuthi kuwe kuwukuthula okuphelele, kuze kube cishe 30 kHz. Uphahla lwakho lungu-20 kHz.
I-Animal Ears yenza kanjani ukuthi umsindo uzwakale njengoba u-Imvu yamanzi ewuzwa?
Ososayensi balinganisile, izinga ngezinga, ukuthi umsindo kufanele ube mkhulu kangakanani ukuze u-Imvu yamanzi 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
Ihhashi
Izindlebe eziphenduka 180° ngayinye: izwa ngemuva kwayo ingashukumi.
Inja
Uzwa ukukhala okuwukuthula kuwe: yingakho izimpempe “ezithule” zisebenza.
Imbuzi
Izwa i-ultrasound, kodwa ibukhali kakhulu ezingeni ngqo lokukhala kwayo.
Imvu
Ububanzi obukhulu kuze kube yi-ultrasound nendlebe emnene ebona ukuthi ngubani okhalayo.
