Mukunzwika kwemuchadenga uye kusvibiswa kweruzha, ambient ruzha mwero (dzimwe nguva unonzi ruzha rwemashure level, reference sound level, kana room ruzha nhanho) ndiyo yekumashure kurira kwekumanikidza panzvimbo yakapihwa, inowanzo tsanangurwa sereferensi nhanho yekudzidza nyowani intrusive ruzha sosi.
Ambient nhanho dzeruzha dzinowanzoyerwa kuitira kumepu mamiriro eruzha pamusoro pehurumende yenzvimbo kuti unzwisise kusiyana kwawo nenzvimbo.
Muchiitiko ichi chigadzirwa chekuferefeta inzwi renzwi contour mepu. Neimwewo mazinga eruzha ambient anogona kuyerwa kuti ape chinongedzo chekuongorora ruzha rwunopindirana kune yakapihwa nharaunda.
Semuyenzaniso, dzimwe nguva ruzha rwendege runodzidzwa nekuyera ruzha rwepakati pasina kuvapo kwekubhururuka kwepamusoro, uyezve kudzidza kuwedzera kweruzha nekuyera kana kuenzanisa kwekombuta kwezviitiko zvekubhururuka pamusoro.
Kana ruzha rwemumugwagwa runoyerwa seruzha rwe ambient, isati yaunza yekufungidzira ruzha barriers inoitirwa kuderedza iyo ambient ruzha mwero. Ambient noise level inoyerwa nemamita nhanho yeruzha.
Inowanzo kuyerwa mu dB pamusoro peyero yereferensi yekumanikidza ye0.00002 Pa, kureva, 20 μPa (micropascals) muzvikamu zveSI. Pascal i newton pa square metre.
Iyo centimita-giramu-yechipiri sisitimu yemayuniti, iyo referensi nhanho yekuyera ambient ruzha mwero ndeye 0.0002 dyn/cm2.
Kazhinji kazhinji ambient mazinga eruzha anoyerwa pachishandiswa frequency weighting sefa, inonyanyozivikanwa iri A-weighting scale, zvekuti zviyero zvinobuda zvinotaridzwa dB(A), kana madecibel pachiyero cheA-weighting.
Ini ndini Joost Nusselder, muvambi weNeaera uye mushambadzi wemukati, baba, uye ndinoda kuyedza michina mitsva ine gitare pamoyo pechido changu, uye pamwe nechikwata changu, ndanga ndichigadzira zvakadzama zvinyorwa zveblog kubva 2020. kubatsira vaverengi vakavimbika nekurekodha nemagitare.
