Zochitika Sound mu zamoyo ndi chikhalidwe zopanda moyo: Zitsanzo

Anthu ambiri akufuna kupeza mayankho a mafunso okhudza zimene zotsatira phokoso, komanso kumene iwo amachokerako. Pa maziko zimene zikumveka wosiyana ndi anthu ena? N'chifukwa chiyani ife tikumva iwo?

Lero tiona gawo sayansi, yomwe ikufotokoza chodabwitsa cha phokoso. gawo limeneli limatchedwa zowulutsira.

Oscillation - chifukwa cha phokoso onse padziko lapansili

Ngati tikumva phokoso, ndiye maganizo tingaganizire konkuno, umene limafalitsa. Choncho, ngati inu kuganizira izo, tiona zimene zimasiyanasiyana. Pamene tilankhula, timinofu kunjenjemera m'thupi lathu. Motero, timamva mawu anu. Zitsanzo za zochitika oganiza sayansi timaona ndi kumva tsiku lililonse.

nkhani za m'mbiri

Anaphunzitsidwa sayansi phokoso zochitika kuyambira nthawi zakale. anzathu wosatha mu moyo ndi mapokoso ndi phokoso. Pali phokoso Phokoso ife okoma, ena kumvutitsa ife. Ndi mawu awa, tinganene kuti phokoso ndi zotsatira phokoso ndi zotsatira zosiyana maganizo ndi thanzi la munthu. Amadziwika kuti ena phokoso munthu akhoza misala, ndipo pali phokoso kuti akhoza kuchiritsa matenda aliwonse anthu. apezazi anapanga munthu pamaso yathu ino. Patapita kanthawi, inu mukudziwa, kodi zotsatira phokoso. Pakali pano, tiyeni tikambirane za kufufuza mu munda wa zowulutsira.

chitukuko wakale

Amazing machiritso zotsatira za phokoso pa ansembe anthu anaona akachisi a Egypt. Mwachibadwa, ndi chodabwitsa ntchito pa zifukwa zachipembedzo. Tsopano Aiguputo mwambo maphwando sanali popanda makolasi ndi nyimbo. Patapita kanthawi, nyimbo ndi phokoso zimaphulika kale mu mipingo yachikhristu. A mkulu mlingo wa luso loimba aliyense katswiri Amwenye. Back mu masiku amenewo analenga ndi mwachangu ntchito kalembedwe nyimbo. Amwenye apasa mbodzi cholembedwa mtengo ena. Otsiriza cholemba osiyanasiyana "osati" amatanthauza chisoni, n'kulemba "Pa" amatanthauza chisangalalo.

Pythagoras - bambo wa zowulutsira

Kuyambira kale, anthu akhala akuyesetsa kufufuza phokoso zochitika. Mwachitsanzo, akale Greek wasayansi ndi nzeru zapamwamba Pythagoras ndi masamu, amene anakhala ndi moyo zaka 2500 zapitazo, anachititsa zosiyanasiyana zatsopano ndi phokoso. Iye anatsimikizira kuti otsika kamvekedwe ka zida n'chobadwa okhawo amene ali ndi zingwe yaitali chifukwa atulukira ake. Pamene chingwe ndi adzafupikitsidwa ndi theka, ndi phokoso kwambiri chifukwa ndi octave wina. Chifukwa anapezazo izi Pythagoras anali pachiyambi cha chigawo cha sayansi - zowulutsira. Woyambirira zida lamayimbidwe analenga Ahelene, amene anakhala mu masiku amakedzana. Iwo anagwiritsa ntchito m'mabwalo. zipangizo izi zakhala ziri mu mawonekedwe a nyanga yaing'ono, ndi zisudzo anaikapo mu chigoba chake kumapangitsanso kuchimva. Mwa njira, zinali zosangalatsa kwambiri chodabwitsa kunong'onezana zifaniziro za milungu ku Iguputo.

Kubadwa Kwatsopano ndi masiku ano

Kwa zaka zambiri, zotsatira phokoso ndipo anapitiriza kuphunzira. Mwachitsanzo, zowulutsira ntchito ngakhale Leonardo da Vinci. Mu zolemba zake, iye anakonza mfundo phokoso mafunde ufulu ku magwero osiyanasiyana. Patatha zaka 400 France mu Paris Academy of Sciences Joseph Saverio lofalitsidwa "Maulendo a zowulutsira". Ndiye Newton anaphunzira ntchito za Saverio. Atafufuza ake ndi mfundo, anakamba mawerengedwe a timaganiza lamayimbidwe. Newton anazindikira kuti timaganiza za phokoso kuwirikiza kawiri chubu kuti umabala ungabva tenepa.

Khama la phokoso

Omwe amatanthauza kuwomba zodabwitsa? Ife chitani tanthauzo la mawu akuti "zomveka". Izi Phokoso makina amene kufalitsa pa TV zotanuka, monga mpweya, madzi ndi zolimba. Chotero Phokoso makina ndazindikira ziwalo Makutu, ndiye makutu athu. Chitsanzo yosavuta, zomwe idzafotokoza akamanena za phokoso adzakhala chingwe cha chida chilichonse nyimbo. Iwo transmits Phokoso ozungulira particles mpweya. Kusinthasintha zofalikira akafika khutu, iwo amayambitsa Phokoso la likalowa m'makutu a. Motero, timamva mosiyana.

zochitika Sound m'chilengedwe

Sound mafunde sangathe kuona. Komabe, inu mukhoza kulingalira momwe iwo adzayang'ana. Kuchita izi, inu muyenera kupita ku thupi aliyense wa madzi. Ngati inu kumuponya mwala mu nyanja kapena dziwe, ndiye mudzaona recess choyamba. madzi pokweza, motero amaoneka padziko funde la posungira, amene alternately alternating ufa ndi crests. Iwo adzakhala kufalitsidwa ku mbali zonse.

Ndime mu zowulutsira

Nkhani zikamera ndi kufala, komanso phokoso mayamwidwe wakhala zowulutsira. Pa zaka zapitazi 10, zowulutsira thupi anatsegula phokoso kuti ali kunja kwa earshot. maphunziro awo ultrasonics. Luso zowulutsira chikuchita ndi ndondomeko ya kulandira, kufalitsa ndi luso kujambula ntchito zipangizo zamagetsi. Chigawo chotsatira amaphunzira kafalitsidwe wa phokoso mu chipinda - kamangidwe zowulutsira. Pakuti n'kofunika osati kukula ndi mawonekedwe a chipinda kumene phokoso ndi ankafufuza, komanso zipangizo kuphimba zipupa ndi denga la chipinda. Nyimbo zowulutsira amaphunzira chikhalidwe ndi chiyambi cha phokoso nyimbo. Pamodzi ndi zigawo zina, pali zowulutsira m'madzi (sonar). Bukuli lakonzedwa kuti kuphunzira zotsatira oganiza malo m'madzi. Sonar n'kofunika kuti chitukuko, komanso chilengedwe cha zokuzira mawu amene angagwiritsidwe ntchito mu sitima zankhondo. Pali mtundu wina - zowulutsira mumlengalenga. Iye amafufuza chodabwitsa cha phokoso mu mlengalenga. Thupi zowulutsira ndi mtetezi mmakutu. Zikomo kwa iye tidziwira mphamvu ya matupi athu, bungwe ndi zochita zawo. mtundu wa maphunziro akuphunzira zowulutsira mawu limba phokoso. Ndi wotsiriza - ndi zowulutsira kwachilengedwenso. Iwo akulankhula nkhani ya kulankhulana akupanga ndi Sonic nyama. Amagwiritsidwanso kuwona malo zimagwirira ntchito ndi nyama, kuwonjezera, zowulutsira kwachilengedwenso cholinga kufufuza vuto la phokoso ndi kugwedera, m'pofunika kuti amenyane phokoso zoipa ndi kusintha chilengedwe.

Nthenda zachilengedwe phokoso zochitika

Padziko lathuli, pali malo odziwika bwino chifukwa chodabwitsa cha mphekesera. Iye amatchulidwa kuti zonse ndi otsika phokoso. Gwero phokoso silinakwaniritsidwe wapezeka. Talas ku New Mexico zoterozo nthenda phokoso likuchokera. Ndi zosadabwitsa kuti phokoso izi anamva 2 okha% ya anthu wamba, iwo amati phokoso ndi ovutitsa kwambiri.

Nthenda zachilengedwe phokoso zochitika

Chimodzi mwa zosangalatsa phokoso munthu anati purring amphaka. Asayansi akufufuza zodabwitsazi. Chiyambi cha mkokomo umenewu simungakhoze adzakhazikika. No zochepa zodabwitsa mu chikhalidwe amaonedwa kukhala zovuta ndi yaitali phokoso lomwe limafalitsa wamwamuna zinsomba linunda. Asayansi ambiri amakhulupirira kuti m'pofunika kukopa zazikazi, koma kafukufuku wa posachedwapa wasonyeza kuti kulira si kukopa akazi ndi amuna.

Mu chikhalidwe, pali ambiri phokoso. Ife tikumva mabingu. Zima pansi pa mapazi athu crunching chisanu. Ngati inu phokoso nkhalango, ife tikumva Echo. Izo, nawonso, ndi chitsanzo cha zochitika phokoso m'chilengedwe.

Choncho, takambirana zitsanzo za zochitika oganiza sayansi ndi chikhalidwe. Tsopano palibe mosamala ntchito simuli mantha.
