Yuav ua li cas khiav hauj lwm hais lus

Tus neeg hais lus yuav tsum tau xaiv raws li qhov chaw nyob thiab suab yuav tsum tau ua, ua ke nrog cov yam ntxwv ntawm tus neeg hais lus. Piv txwv li, rau sab nraum zoov kev tshaj tawm uas yog feem ntau yog lub suab-raws li, lub tshuab hluav taws kub tau xaiv tau. Yog tias yuav tsum tau zoo dua qub yog qhov yuav tsum tau ua, muaj lub thawv hluav taws xob lossis lub suab yuav tsum raug xaiv. Rau kev tshaj lij sab hauv tsev, kev me me hauv lub thawv ua los ntawm ib daim ntawv hluav taws xob cov lus hais tau tuaj yeem xaiv tau. Txog kev ua suab paj nruag lossis lub rooj sib tham zoo ua kom zoo, lub thawv hais lus muaj kev sib xyaw ntawm kev sib xyaw ntawm cov neeg sib xyaw ntawm cov neeg siab thiab qis-ntau zaus.
Thaum siv tus hais lus, them sai sai rau cov ntsiab lus hauv qab no:
(1) Lub zog tau los ntawm tus neeg hais lus yuav tsum tsis pub dhau nws lub zog hluav taws xob, txwv tsis pub lub suab cheeil yuav raug hlawv lossis lub suab cheeil yuav tau tawg. Cov kev ua haujlwm ntawm voltage ntawm electromagnetic thiab piezoelectric cerician cov neeg hais lus yuav tsum tsis pub dhau 30v.
(2) Nco ntsoov tias lub cmpedance ntawm tus neeg hais lus yuav tsum sib phim nrog cov zis hluav taws xob. Rau cov hau kev tshwj xeeb, thov saib rau ntu ntawm Ampifiers.
(3) Xaiv tus qauv uas raug. Yog siv nyob rau hauv ib lub xwmfab, ib tug bass hais lus yuav tsum tau xaiv; Yog tias siv cov ntaub ntawv hauv tsev, cov ntawv xov tooj lub ntsej muag yuav tsum tau xaiv thiab ib lub thawv zoo hais lus yuav tsum tau xaiv. Lub siab thiab tsawg-zog hais lus tseem tuaj yeem ua rau hauv ib pawg neeg hais lus kom nthuav cov lus teb ntau zaus.
(4) Thaum npaj cov neeg hais lus, lub suab yuav tsum muaj felly faib thiab nyob ntawm ib theem txaus. Yog tias ib qho (point) hais lus tsis tuaj yeem ua tau raws li cov kev xav tau, ntau cov ntsiab lus tuaj yeem tsim kom txhua lub suab nrov nrov thiab txhim kho cov suab daws teeb meem; muaj kev paub zoo ntawm kev taw qhia. Cov neeg hais lus yuav tsum tau nruab ntau tshaj 3 meters saum av kom cov neeg mloog lus tuaj yeem "pom" cov neeg hais lus, hais lus (hais lus) raws li tau, thiab qhov kev ncua deb ntawm ob Cov neeg hais lus yuav tsum tsis loj dhau.
(5) Rau cov neeg siv hluav taws xob, lub taub hau suab yuav tsum muab tso rau ntawm lub tshuab raj ua ntej siv, txwv tsis pub nws yooj yim rau kev puas tsuaj lub suab lub taub hau.
(6) Thaum siv ntau tshaj ob tug hais lus ua ke, xyuam xim rau theem teeb meem. Yog tias lawv tau rov qab ua ntu zus, lub suab yuav tsis muaj zog. Txoj kev yooj yim tshaj plaws los txiav txim siab rau theem ntawm tus neeg hais lus yog siv lub siab ntsuas ntsuas ntawm 50 ~ 250μμa, tuav cov ntawv xov nrog ob txhais tes, thiab thawb nws nyuaj. Nyob rau lub sijhawm no, koj tuaj yeem txiav txim siab lawv theem los ntawm lub viav vias ntawm lub cav meter '. Yog tias theem yog tib yam, lub cav viav vias nyob rau hauv ib qho kev taw qhia. Nyob rau lub sijhawm no, lub suab chev txhuas txuas nrog txoj kev xeem ua tau zoo tuaj yeem raug suav tias yog "kaum" qib.
