Umsindo ezingeni

Noise ukuxuba esingalawuleki imisindo ehlukene. Ubunjalo bomuntu kukhona umthamo yayo decibel angu. Abonisa degree of ingcindezi umsindo.

Izinga umsindo for ntu ku uhla evamile ivela decibel angu amabili kuya amathathu. Lokhu ivolumu yemisindo akakwazi zibangele noma iyiphi umonakalo kanye kubhekwa ukhululekile. Ngokwesibonelo, umsindo udaba sengiprofethile enjalo eshiya phezu kwezihlahla. Nokho, umuntu ngamunye unika izintandokazi ngazinye izinga elithile umsindo kuma. Kukhona abantu, umsebenzi onzima olungena kakhulu uma kukhona ethule kakhulu. Ukuqeda ukuqaleka zingase zihlanganise umculo wangemuva. Ukuthula kumele ngobugebengu abanye kuphela iwashi kuboniswe ngophawu.

Izinga umsindo, okuyinto kukalwa at ibanga kwamamitha amabili ukusuka impahla, ngokuvumelana izincomo ezempilo, akufanele kube ngaphezu kwama-decibel angu amahlanu nanhlanu. Lena umsindo ingxoxo evamile phakathi kwabantu noma abilayo ngeketela isitofu (uma kusuka kuye isigamu imitha).

Emadolobheni amakhulu ngokugcinwa lezi zilinganiso akunakwenzeka. Nikela kule omkhulu omatasa nokwakhiwa entsha. Izinga umsindo e-decibel angu kusukela imoto eyayidlula eduze nawe kuyoba mayelana ayisikhombisa. Motorcycle, ibhasi iloli kusenze ubuhlungu nakakhulu. amazinga yabo umsindo ukufinyelela umngcele decibel angu ayisishiyagalolunye. Ngakho, abadlula endleleni, indoda ucosha nemisindo siphezulu kunamanye kuyinsakavukela sanitary.

Iziteshi Level futhi zezindiza umsindo ezimpilweni zethu esiphezulu. Izitimela izindiza akwazi imisindo ivolumu isifinyelele umkhawulo eyikhulu decibel angu.

amagugu ephakeme umsindo omkhulu ovela ngemuva ayingozi empilweni yomuntu. Uma njalo wethu izinhlaka kokuzwa ithonya umsindo okwedlula ama-decibel angu ayisishiyagalombili, uma ubhekene nesimo esinjena ubhekwa ingozi emzimbeni. Basebenti labasebenta ezimweni ezinjena ukukhiqizwa kumele ngezikhathi ukunikeza isiqondiso ukuze lapho ngihlolwa.

Izinga umsindo wehlele kuze kube semngceleni ayikhulu namashumi amathathu-decibel angu-kungabangela ubuhlungu ngokomzimba. Omunye namashumi amahlanu uphawu kubangela nokulahlekelwa ukwazi. Eziyikhulu namashumi ayisishiyagalombili-decibel angu ukubhubhisa metal futhi ziyabulala. Ngenhlanhla, ngokoqobo kwansuku amazinga ezifana ingcindezi kukalutshwana kakhulu.

Ukuze uqonde ukuthi imvelo kuyingozi empilweni yakho, kumele ukuxazulula inkinga ukuthi ukukala kunomsindo. Ngenxa yale njongo kukhona idivayisi ekhethekile, etholakalayo ezinguqulweni ezahlukene. Ibizwa ngokuthi umsindo imitha ezingeni. Ukuze ukukala ivolumu ubufakazi endaweni yokuhlala, kukhona ezifuywayo, zezimboni - amadivayisi ezimbonini. Futhi ukhiqiza anhlobonhlobo ezingeni amamitha umsindo, ekwazi ukuba siqonde ezingeni infra- futhi ultrasounds.

Tona, ukuqamba amanga ngaphakathi imisindo ephansi, futhi okusezingeni eliphezulu ziqondakala njengoba ethule ngaphezulu. Imitha umsindo ezingeni unikezwa isihlungi ekhethekile electronic okuyinto modulates izinkomba ehlukahlukene standardizes nesilinganiso.

Njalo imisindo elikhulu ukunciphisa ngabo ngezindlebe zethu. imisindo elikhulu, zingaba imbangela ethola ukuhlukumezeka acoustic. Lokhu zokugula kungaba oyingozi noma ezingamahlalakhona. Uhlobo lokuqala ukulimala ingatholakala ebukhali imisindo, okuyinto wawuzwakala eduze endlebeni (uphondo isitimela Ukudlula, ukuduma kwayo i ukufakwa). Umphumela lolu hlobo lwempendulo kungaba:

- ubuhlungu auricle;

- ukopha zangaphakathi;

- ukuvuvukala kanye displacement we amaseli elise zengaphakathi lendlebe.

Phakathi nenkathi ethile, kubonakala umuntu owafika ubuthulu. Ngezinye izikhathi umsindo ophakeme uzilimaza kungabangela ukudabuka we ulwelwesi tympanic.

Nge ukuhlala njalo eside endaweni enomsindo kukhona uhlobo ezingamahlalakhona ukuhlukumezeka acoustic. okuwumphumela iyona onokuqundeka ukuzwa.
