Nhasi, Vagari dzakawanda itsva, yakarongedzwa mufurati, kumanikidzwa kuita mamwe basa, kusanganisira mudziye mudzimba dzavo nokuti mureza zvakashandiswa kubvumira yapera vanovanza zviri kuitika kumba kwako, uye vasingafariri kurara pamusoro kuda vavakidzani vavo.
At kumhanya inzwi iri nezvishoma inokanganisa zvichida arambe achirema uye elasticity mashoko, kuti vamise. Saka, muna midziyo nzvimbo rukoko yakabatana ukaramba parusvingo, akaita soundproof ne "bindepinde" kubva kumusoro uye pasi. Kunoitawo kuti kuderedza ruzha pamwero mu decibels, dzimwe nguva zvakawanda kupfuura 10 nguva. Ipapo vakaisa basalt nepanhovo, uye pamusoro - gypsum mapuranga, izvo vanoratidza kurira chokunze kubva mufurati. Kana inzwi chinozunguzirwa "nhunzi" zvakadaro urongwa, izvozvo dzinopera kupinda insulator akaturikidzana dziri porous uye munyoro. Kana kurira ane guru simba, zvinhu tibatsirwe payo, unogona kunyange vakuchidzire.
Kwakavharwa nenyama chete fuma, zvakadai semvura, huni, simbi, zvakanaka fambisa ruzha, saka tinonzwa anoshamisa "kuimba" zvemimhanzi. Vamwe vanhu kare kuziva nzira Somuenzaniso, vatasvi, vachiisa nzeve yake pasi, riri zvakakwana kwakavharwa nenyama.
Kumhanya nepfungwa? Km zvichienderana zvinoitwa kwezvakatipoteredza nayo asiwo. Kunyanya, izvi kunogona kukanganisa kwaro kumanikidzwa, makemikari anoumba, tembiricha, elasticity, arambe achirema nezvimwe parameters. Somuenzaniso, simbi jira rinopfuura ruzha ari kumhanya 5100 metres por wechipiri, magirazi - vanenge 5000 m / s, uye girenayiti mumuti - vanenge 4000 m / s. Uchatamisa nokukurumidza mune makiromita paawa anofanira kuva kwakawanziridzwa yemagazini 3600 (masekonzi paawa) uye chakaparadzanisa ne 1000 (metres pa kiromita).
Kumhanya inzwi iri? Km nenzira aqueous svikiro yakasiyana kuti zvinhu pamwe salinities zvakasiyana. Nokuti mvura yakachena ari tembiricha 10 Celsius, zviri pamusoro 1450 M / s uye ari kudziya 20 Celsius uye zvakafanana kufurirwa - anenge 1490 m / s.
Sesaline chete mamiriro ezvinhu zvakajeka yepamusoro kukurumidza kupararira inzwi vibrations.
Mashoko inzwi mumhepo zvakare tembiricha zvaanoda. Kana kukosha parameter ichi akaenzana 20 Celsius, kuti ruzha kupfuura ane velocity anenge 340 m / s, riri pamusoro 1200 km / awa. A razero madhigirii ichimhanya DZEMUNHU DZINODZORA kusvika 332 m / s. Tichidzokera insulators kwatinoita Apartments, tinogona kuona kuti pane zvinhu zvakadai, akadai koko, iro rinoshandiswa kuderedza huwandu kwokunze ruzha, nenzwi velocity iri makiromita ndiyo 1800 chete km / h (500 metres pa wechipiri). Izvi kagumi kuvatumwa kuti hwendarira unhu zvizere.
Kurira wave munhu longitudinal oscillation kwezvakatipoteredza nayo asiwo. Kana achipfuura Somuenzaniso, nhindi mumhanzi mimhanzi yaunonyanya kuburikidza chigumbuso, padanho bhuku racho ipfupi, nekuti kuchinja kuti oscillation amplitude. Kakawanda inoramba chete, saka kuti tinonzwa hadzi inzwi sezvo munhukadzi uye munhurume - sezvo murume. The dzinonakidza zvikuru ndiyo nzvimbo kurira nokukurumidza muna? Km riri pedyo razero. Izvi - vacuum umo iri mhando mafungu vari asiri inoparadzirwa. Kuti aratidze kuti ichi inoshanda, yefizikisi akaisa achirira aramu wachi iri Hood, umo mhepo iri pumped. The zvakawanda zviri husiri nyore kuwana dzedenga, iyo yakanyarara akanzwa chikumbiro.
