Sound vibrations. Practical aikace-aikace. Tasiri a kan mutum

Rayuwa a duniya na daban-daban tãguwar ruwa, daya kullum ji da tasiri na sauti. Sound vibrations - shi ne ba kawai wani sabon abu rakiyar shi a ko'ina, amma kuma tushen yardarSa, amma kuma mai iko bayanai kayan aiki. Yin wani iri-iri na ayyuka, da sauti ne iya yi gargaɗi game da hadari, da yarda, zama hanyar sadarwa. Muna farin ciki da sauraron tsuntsaye singing, taushi da music, shiga cikin wani zance da sauran mutane.

Sound vibrations suna da muhimmanci ba kawai ga mutane amma kuma ga dabbobi da cewa amfani da sauti zuwa tsira.

By da yanayi, da sauti ne mai inji na roba tãguwar ruwa, wanda suke iya yada a daskararru, taya, gas a. Sound kafofin Sound vibrations sa vibration (inji oscillations), wanda sau da yawa marar ganuwa ido. By da sauti kafofin iya hada jiki jikinsu wajen yin vibrations da biyu (shudder ko vibration) tare da wani mita na da zarar 16-20000. Sound vibrations iya haifar da m jikuna (kirtani ɓawon burodi), gaseous (iska jet), ruwa (teku tãguwar ruwa).

Daga cikin sauti halaye na rarrabe biyu sigogi: da murya - mita sauti vibrations. girma - a Sonic kalaman mawadãta. A naúrar na girma yana dauke su 1 Bel (da shi da aka mai suna bayan daya daga cikin kirkiro na tarho - Aleksandra Grehema Bell). Kusan daya Bel ba a amfani da, shi ne mafi dace don amfani decibels, daidai to daya cikin goma na Bel. Domin samun bayyananne ra'ayin da girma da ƙarfi da za a dauka la'akari da cewa 10 DB - gãnãwa shi. 20-30 DB dace ga saba amo a cikin falo. 50 DB - wannan ne talakawan kira girma. wani amo ikon a 80 DB truck engine ne a guje. physiological zafi bakin kofa a cikin mutane ya auku a 130 DB. 180 DB iya kai wa ga katsewa na eardrum.

Idan akai la'akari da sauti tãguwar ruwa na daban-daban mitoci, a high-mita tãguwar ruwa hada da tsarkakewa daga tsuntsãye, to da low sauti hada da sauti na babbar mota engine. Tare da duk kewayon Properties da halaye cewa bambanta tãguwar ruwa na daban-daban yanayi, da sauti tãguwar ruwa suna yadu amfani a fannoni daban daban. m Properties sun sauti ne rayayye yi amfani da bincike na cikin tẽku mai zurfi. Dukan da aka sani amo mara sa, misali, an yi amfani da sanin nisa a echolocation. A karin misali za a iya ambata halitta Sonar jemagu.

A musamman irin duban dan tayi Ft Irfan vibrations ne sosai tasiri wajen a hannun likitoci da kuma sauran masu bincike. Wadannan vibrations ne taguwar ruwa tare da mitoci na 20 000 Hz. Wannan oscillation yanayin yana da yawan musamman Properties. Wucewa ta hanyar ruwa, da duban dan tayi ne da tafasar (cavitation) da abin da ya faru na ruwa guduma. Amfani da duban dan tayi abubuwa iya cire daga surface na karfe murkushe daskararru. Duban dan tayi damar hadawa da ruwaye wanda suke immiscible karkashin talakawa yanayi, misali, emulsions da mai tushe. Duban damar da saponification na fats. Wannan manufa ta'allaka a na'urar injin wankin. Property na duban dan tayi samar da crushing sakamako da aka yi amfani da ultrasonic soldering baƙin ƙarfe.

A musamman irin vibrations up to 16 Hz aka kira infrasound. An sani cewa vibrations wannan mita iya zama mai raɗaɗi sakamako a kan jikin mutum. A mitoci na 4-8 Hz aka ji vibration na ciki gabobin, da mita a 12 Hz triggers wani tashin zuciyar teku.

A kafofin iya zama infrasound kayan da manyan saman, wanda sa inji vibrations na low mita (inji asalin) ko taya da gas gudana tare da m Properties (hydrodynamic ko da nata irin asalin).
