Pane zvikonzero zvakawanda nei tingada kuziva mwero weruzha rwakatipoteredza. Somuenzaniso, kana tine muvakidzani anofarira kuridza mimhanzi zvakanyanya, kana kuti kuziva mwero weruzha rwemhoteredzo rwatinogona kutsungirira munzvimbo yedu yebasa. Muzviitiko zvese izvi, iyo mapurogiramu ekuyera ma decibels. Mune ino post tichaongorora zvimwe zvezvakanakisa.
El decibel (dB) ndicho chiyero chinoshandiswa kuratidza chiyero chesimba kana kusimba kwezwi. Chikumbaridzo chekunzwa chenzeve yemunhu chinopiwa kukosha kwe0 dB. Huwandu uhu hunenge hwakaenzana, zvakanyanya kana zvishoma, nehwokunyarara zvachose, kunyangwe munhu mumwe nemumwe aine kunzwa kwakasiyana.
Kuti tive nefungidziro yehuwandu hwema decibels, ndiko kuti, mwero weruzha rwatinoratidzirwa muhupenyu hwedu hwezuva nezuva, tinogona kupa mimwe mienzaniso: ruzha rweizwi remunhu muhurukuro yakajairika (pasina kudanidzira) inenge 40 dB, iyo yevacuum cleaner inoshanda panguva yekuchenesa imba i70 dB uye iyo yemagetsi 90 dB.
Sangano reWorld Health Organisation (WHO) rinogadzira muganho we55 dB seyakanyanya kushiviririka kuti pave nekugara kwakakwana. MuSpain, ndiwo makanzuru emutaundi anotarisisa huwandu hweruzha hunobvumidzwa munzvimbo dzekugara, mukati memiganhu yakatarwa ne Noise Law. Kazhinji, zviyero zvinotevera zvinoshanda:
- Pakati pezuva (kubva 8am kusvika 22 p.m.) haugone kudarika 35 dB.
- Husiku (kubva 22 pm kusvika 8 am) muganhu uyu unoderedzwa kusvika pa30 dB.
Aya maawa uye mazinga anogona kunge akasiyana pazororo nekupera kwevhiki, kunyange zvakadaro zviri nyore kuvaziva uye kuvaremekedza kudzivirira zvirango zvehupfumi zvehutungamiri. Apa ndipo panopinda ma decibel metres, kana zvirinani, maapplication ekuyera ma decibels: kuziva kuti tiri mukati memutemo.
Sound Meter (SPL)
Kunze kwehunyanzvi hwemhando yepamusoro chiyero mamita, iyo app Sound Meter (SPL) Ndicho chimwe chezvishandiso zvakanakisa zvatinga shandisa kuyerwa kwemanzwi uye ruzha rwezvakatipoteredza. Acronym SPL inomirira Kudzvinyirira Kunzwi, zvinova ndizvo chaizvo zvinoyerwa neapp iyi nehupamhi hwekugadzirisa zvakanaka.
Imwe yekuwedzera ndeye yayo yakanaka interface, iyo yekuona chimiro chatinogona kugadzirisa neyakasiyana dhizaini inofemerwa neyekare kana vintage-style gauges. Mhinduro yakanakisa, pamwe nekuita.
Decibel X
Yakanakisa inzwi mita, yakanyatsojeka uye yakavimbika. Decibel X Inopa pre-calibrated zviyero zvinogona kusanganiswa nemamwe maapplication uye zvakare inotitendera kugadzira nhoroondo uye kugovera mhedzisiro yezviyero zvedu kuburikidza nesocial network.
Iine mwero wechiyero kubva pa30 dB kusvika 130 dB, mibairo inoratidzwa uchishandisa inoshanda magirafu munguva chaiyo. Iyo ine zvakare "Chengetedza mudziyo wakamuka" basa kuita zvinyorwa zvenguva refu, semuenzaniso, kuziva ruzha rwehofisi mukati mezuva rose rekushanda. Zvakanyanya kushanda.
Sound Analyzer
Inyanzvi yekuteerera mita inotipa yakadzama uye yakavimbika ruzivo pane ambient ruzha mazinga. Sound Analyzer Iyo inokwanisa kuita ongororo yeharmonic yematanho akasiyana uye kutipa mufananidzo wakajeka wavo.
Haisi mita yeruzha kushandisa, asi a sophisticated tool izvo zvinoda ruzivo rushoma rweacoustics kune chikamu chemushandisi. Mhedzisiro dzayo dzinopa ruzivo rwehunyanzvi rwunogona kunge rwakanyanya kune vanhu vazhinji, asi kune hunyanzvi kushandiswa kunogona kunakidza. Chero zvazvingaitika, isu tinongokurudzira iyi app kune nyanzvi.
Sound Meter Pro
Kuvhara rondedzero, imwe yemaapps makuru ekuyera ma decibel atiinawo. Sound Meter Pro ndeyemahara application asi inokwanisa kupa nyanzvi nhanho yekuyera kuyerwa. Izvi zvinodaro nekuti yakagadziridzwa uchishandisa Nor140, iyo yakakwirira chaiyo yekurira nhanho mita.
Pamusoro pekuyera mazinga eruzha kwezvakatipoteredza, iyo app inoita kuti tichengetedze zviyero zvedu nenzvimbo dzinoenderana. Iyo ine nyore uye inoyevedza interface. Kuratidzawo zvake vibrometer yakasanganiswa iyo inoshandisa yekumhanyisa sensor kuyera kuzunguzika kwakasimba. Kana kunyange seismic kufamba.
Nekupedzisa, zvakakosha kuziva kuti maapplication anobatsira kusvika papi kuyera ma decibel tichishandisa nharembozha dzedu. Sezvataona, ndizvo zvishandiso zvinoshanda uye zviri nyore kushandisa zvavanogona kutipa kuverenga kwakavimbika nezve acoustic mazinga emba kana yebasa. Nekudaro, mhedzisiro yayo haishande mukati meOccupational Hearing Conservation Programme kunze kwekunge kuyerwa kwaitwa pachishandiswa maikorofoni yerudzi rwechipiri uye neyakatenderwa mudziyo calibration pamberi uye mushure meyero yega yega.
