The gudun sauti. Sound effects a yanayi da fasahar

Don gano a duniya kewaye da mu kasance cikin ikon ji da mutum a matsayin kyauta ne daga yanayi. Saboda wannan da muke da damar da za su ji dadin trill tsuntsaye da guda na music, samun-gargadi sakonni game da hatsarori da kuma sadarwa tare da juna.

Idan akai la'akari da yanayin sauti, kimiyyar lissafi ba da amsa da cewa muna da ake rubutu da inji tãguwar ruwa. Domin rarraba, dole ne ka da wani na roba matsakaici. Amsar wannan tambaya na abin da yake gudun sauti a wani wuri a karkashin manufa yanayi (cikakken rashin abu) ya nuna kanta. A cikin injin ya ba zai iya propagate. Sound gudu daidai da daidaita da sifili. Amma wannan ba ya nufin cewa babu wani sarari a cikin comic Ft Irfan mamaki. Wasu suna quite explainable yanayi da kai tsaye alaka da ci gaban bude sarari na mutum sarari. Ruri daga injuna a motocin, da sauti vibrations a cikin sarari jigila. A wasu mamaki da duk da haka a sami wani bayani, misali, kamar sautin da bi cosmic haske, ko low-mita "burbushi" na kumbon sama jannati.

A daban-daban yanayi da gudu daga sauti yana da wani daraja empirically. Its baza aka shafi gaban cikas. Ganin cewa muna anfani da inji tãguwar ruwa, za mu iya ganin yadda sauti da ke kewaye da wadannan matsalolin. Wannan sabon abu da taguwar ruwa kira diffraction. Low taguwar ruwa mafi amenable gare shi fiye da high. Khor, sunã mãsu jũyãwa da kusurwa, da farko "hasarar" high muryoyin, sa'an nan ya zama inaudible low mawaƙa murya.

A sakamakon sauti tãguwar ruwa a kan mutum kiwon lafiya tunani tun kafin bude infrasound. A janareta inaudible sauti mitoci iya shafar da yanayi na manyan yawa na mutane. Saboda haka, da kimiyyar lissafi of America Robert Wood ne aka yaba da wajen m gwaji. Ya kwashe wasan kwaikwayo infrasound janareta, juya shi a kan da kuma shaida yadda duk 'yan kallo rungumi sabon abu restlessness da kuma tashin hankali.

Ko irin wannan sabon abu kamar yadda fitowan da "tashi Dutchmen" - jiragen ruwa tare da matattu tawagar, kokarin bayyana rinjayar infrasonic mitoci generated teku abyss a lokacin hadiri.

Ganin yanayi na yaduwa daga sauti tãguwar ruwa, shi za a iya ƙarasa da cewa gudun sauti a daban-daban yanayin yana da daban-daban girma. An lura da cewa sauti farfagandar a gas a daban-daban gudu. A wannan aiki bangaren ba da tasiri da yawa daga gas, shi ya dogara da kwayoyin nauyi.

A taya, da sauti ko da tafiya da sauri. A nan ne kawai da mugun mutum kunne bambanta da shi a cikin irin wannan yanayi. Sound tãguwar ruwa yada a cikin ruwa, kusan gaba daya nuna daga cikin eardrum. Amma Leonardo Vinci ya sami wani asali hanya don sauraron karkashin ruwa sautuna. Don wannan karshen, ya nuna da yin amfani da saukar zuwa cikin ruwa filafili. Idan muka kwatanta da gudun sauti a iska (331 m / s) da kuma ruwa (1435 m / s), shi ne zai yiwu zuwa waƙa da jinsin amfani denser matsakaici domin rarraba.

Daskararru doke duk records. The gudun sauti a kansu iya isa 5000 m / s. An ban sha'awa kwarewa za a iya yi da na kowa dogo kwasfa da kunne. Idan wani a cikin nesa buga shi tare da guduma, za mu iya fili ji biyu hits. Farko - wannan ne sauti bayanai samu ta hanyar yada karfe, da kuma na biyu - da kalaman zo ta iska.

Ga wani babban yawan na jiki mamaki sauti gudu ne a irin misali, masomin kwatanta. Modern mayakan daukarsa a matsayin mafi girma da nasara da ya supersonic damar. Aunawa da nassi daga wani rabo daga sauti kalaman, yana yiwuwa domin sanin da nisa da high daidaituwa.

Amfani da rinjayen sauti a daban-daban duniyoyin na mutum aiki aka karin domin ta bambancin.
