Sound Phokoso. Othandiza ntchito. Impact pa anthu

Kudzakhala m'dziko mafunde ina, ndipo nthawi zonse amamva zotsatira za phokoso. Sound Phokoso - si chinthu ankatsagana naye kulikonse, komanso osangalatsa, komanso chida champhamvu zambiri. Kuimba nyimbo zosiyanasiyana ntchito, phokoso amatha amachenjeza za kuopsa, zosangalatsa, kukhala njira zolankhulirana. Timasangalala kumvera mbalame kuyimba nyimbo zofewa, kulowa kucheza ndi anthu ena.

Sound Phokoso ndi zofunika osati anthu komanso nyama kuti ntchito phokoso kupulumuka.

Ndi chikhalidwe chake, phokoso ndi makina zotanuka mafunde, okhoza kufalitsa mu zolimba, zakumwa, mpweya mu. magwero Sound Sound Phokoso chifukwa kugwedera (makina oscillations), chomwe nthawi zambiri wosaoneka diso. Ndi phokoso magwero angakhale monga matupi aumunthu wokhulupirira Phokoso pa mphindi (kunjenjemera kapena kugwedera) ndi pafupipafupi kamodzi 16-20000. Sound Phokoso zikhoza matupi olimba (chingwe kutumphuka), gaseous (mpweya ndege), madzi (mafunde nyanja).

Mwa makhalidwe phokoso kusiyanitsa magawo awiri: liwu - pafupipafupi phokoso Phokoso; buku - ndi Sonic yoweyula matalikidwe. Unit voliyumu akuti ndi 1 Bel (izo unatchedwa mmodzi wa anayambitsa telefoni - Aleksandra Grehema Bell). Pafupifupi gawo limodzi Bel si ntchito, ndi yabwino ntchito decibels, Angafanane ndi khumi wa Beli. Kuti ndi lingaliro bwino ndi gawo la voliyumu kuti n'komwe kuti 10 DB - alira izo; 20-30 DB zogwirizana ndi phokoso mwachizolowezi mu pabalaza; 50 DB - izi ndi pafupifupi foni buku; mphamvu phokoso 80 DB galimoto injini ndi akuthamanga; thupi ululu pakhomo anthu amapezeka pa 130 DB; 180 DB kungachititse kuti chotupa cha likalowa m'makutu a.

Poganizira mafunde phokoso la mafurikwense osiyana, mafunde-pafupipafupi monga nyimbo za mbalame, ndi phokoso otsika monga phokoso la injini galimoto. Ndi uthunthu wonse wa katundu ndi makhalidwe zosiyana mafunde a chikhalidwe chosiyana, mafunde phokoso ankagwiritsa ntchito zosiyanasiyana. katundu madzimadzi anali zogwira ntchito mwakhama kufufuza la nyanja. kumatikumbutsabe onse odziŵika Mwachitsanzo, ntchito kudziwa mtunda mu echolocation. A chitsanzo chapadera akhoza kutchulidwa zachilengedwe sonar mileme.

A mtundu wapadera wa ultrasound lamayimbidwe Phokoso ndi njira kwambiri manja a madokotala ndi ochita kafukufuku ena. Phokoso Awa ndi mafunde ndi mafurikwense 20 000 Hz. Izi mode oscillation angapo a wapadera katundu. Kudutsa madzi, ultrasound ndi kuwira ake (cavitation) ndi zosayembekezereka ya nyundo madzi. Kugwiritsa ntchito zinthu ultrasound akhoza detach padziko zitsulo udzaphwanya zina zosafunika. Ultrasound amalola kusanganikirana madzi amene ali immiscible m'mikhalidwe wamba Mwachitsanzo, emulsions ndi m'munsi mafuta. Ultrasound akulola saponification kunyama. Mfundo imeneyi chagona pa chipangizo makina ochapira. Katundu wa ultrasound kubala onongani zotsatira wakhala ntchito akupanga soldering chitsulo.

A wapadera Phokoso mpaka 16 Hz amatchedwa infrasound. Amadziwika kuti Phokoso la pafupipafupi izi zingakhale zopweteka zotsatira pa thupi la munthu. Pa mafurikwense wa 4-8 Hz ndi kuchisonyeza kugwedera kwa ziwalo, pafupipafupi pa 12 Hz akapsa ndi seasickness.

magwero kungakhale infrasound makina ndi pamalo lalikulu amene amapanga kunjenjemerako makina a pafupipafupi otsika (chiyambi mawotchi) kapena zakumwa ndi mpweya loyenda katundu chipwirikiti (hydrodynamic kapena chiyambi kuuluka bwino potsatira njira).
