Nekuti gore rino, shamwari zhinji dzakabvunza kana kuisirwa kwemutinhimira kunoshanda, saka govana.
Sezvambotaurwa pamusoro apa, mhedzisiro yeizwi chipingamupinyi iri pamusoro pekugona kuderedza ruzha rwekuvharisa ruzha, izvo zvinoreva kuti ruzha runogona kudzikiswa kubva pahuwandu kusvika pahuwandu.Inotevera itsananguro iri nyore:
(1) fekitori yakaisa ruzha barriers effect, mune izvi zvinoratidza kuti pane zvinhu zviviri: chimwe ndechekuti mukati mefekitori, kana kuisirwa kuri kunobata fekitori inobata mutsindo wemukati unoshanda kuderedza ruzha kunogona kusvika makumi matatu decibel noise barriers kutenderedza nyaya iyi inoda ona ruzha decibel level, kune chinhambwe, asi ruzha rwekuzviparadzanisa pakati penzvimbo yemukati yehofisi nenzvimbo yekugadzira, nzvimbo yehofisi kazhinji inogona kudzikiswa kusvika makumi mana db pasi peruzha.Imwe yacho iri kunze kwefekitari, senge mativi mana kana rimwe-sided ruzha rwekuvharidzira, kuseri kweiyo ruzha barrier test, ruzha ruzha harungapfuuri makumi mashanu db.
(2) mhedzisiro yemugwagwa mukuru wekumisa ruzha.Sezvo highway sound barriers inogaroiswa chinhambwe chinodarika 50 metres kubva kuvagari vakatenderedza mugwagwa mukuru, inoedzwa isingasviki makumi mana db muyadhi yevagari, uye inosvika makumi mashanu db padivi pechivharidzo, ukuwo 160 db ruzha. inoedzwa zvakananga mumugwagwa mukuru mushure mokusiya ruzha.Chii chinoderedza ruzha mhedzisiro yekudzvanya highway noise barriers?Tarisa vhidhiyo inorarama.
(3) mushure mekuiswa kwenjanji inonzwika barriers, ruzha runogona kudzorwa pasi pe50 db uye pasi pe40 db munzvimbo yekugara.Kunyatsoenderana nemitemo yenyika.Iyo chaiyo mhenyu vhidhiyo inogona kuratidzwa nekudzvanya pane mhedzisiro inoratidzwa yeyakakwira-kumhanya njanji ruzha barriers.
Mhedziso: iyo iri pamusoro ndiyo chaiyo mhedzisiro mushure mekuisa iyo ruzha barriers.Ndinokutendai nekuverenga kwenyu.Kana iwe uchida rumwe ruzivo, ndapota bvunza yedu online vatengi sevhisi.
