Animal Ears 🐦 Yileyo ndlela izilwane ezizwa ngayo
U-i-hummingbird uzwa kanjani?
Lampornis clemenciae
Ihlabelela amanothi aphakeme kunalawo ekwazi ukuwezwa.
Ngamafuphi
U-I-hummingbird uzwa cishe kusukela ku-300 Hz kuya ku-7 kHz, futhi ubamba kangcono eduze kuka-2 kHz. Nge-Animal Ears ungathatha noma yimuphi umsindo wakho bese uwuzwa ngendlela ayizwa ngayo.
I-hummingbird enomphimbo oluhlaza inokuzwa okuncane kakhulu: kusukela ku-300 kuya ku-7 000 Hz, kungcono eduze kuka-2 000. Okuthakazelisayo yilokho ekwenzayo ngalowo mkhawulo: ikhiqiza amanothi angaphezu kuka-7 000 Hz, okusho aphakeme kunalawo ebonakala ikwazi ukuwezwa. Mhlawumbe asiza kokunye, mhlawumbe iyawabamba ngendlela esingakayiqondi. Elinye lalawo macala akukhumbuza ukuthi uhlobo ngalunye luzwa inguqulo yalo yomhlaba.
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 | 300 Hz |
|---|---|
| Umsindo ophakeme kakhulu | 7 kHz |
| Umsindo awuzwa kacace kunayo yonke | 2 kHz |
| Okuzwa wena | 20 Hz – 20 kHz |
Izindlebe zakho vs. ezika-I-hummingbird
Ngakolunye uhlangothi uphuthelwa imisindo ephakeme oyizwayo wena: ngaphezu kuka-7 kHz, kuye akusekho lutho.
I-audiogram
| I-Hertz (Hz) | Umkhawulo wokuzwa |
|---|---|
| 500 Hz | 48 dB |
| 1 kHz | 26 dB |
| 1.5 kHz | 18 dB |
| 2 kHz | 15 dB |
| 3 kHz | 20 dB |
| 4 kHz | 33 dB |
| 5 kHz | 46 dB |
| 6 kHz | 57 dB |
| 7 kHz | 70 dB |
From the one published hummingbird ABR audiogram: best ~1–3 kHz, effectively no hearing above ~7 kHz. ABR thresholds are elevated vs behavioural — use the curve shape. (Duque et al. 2020 is cited for comparison only; it concerns a different species, the Ecuadorian hillstar.)
Ingabe u-I-hummingbird uzwa izinto ongenakuzizwa wena?
U-I-hummingbird ubamba konke kusukela ku-300 Hz (ophansi kakhulu) kuya ku-7 kHz (ophakeme kakhulu), futhi uzwa kacace kakhulu eduze kuka-2 kHz.
Ngakolunye uhlangothi uphuthelwa imisindo ephakeme oyizwayo wena: ngaphezu kuka-7 kHz, kuye akusekho lutho.

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