Iziphumo aziduduzi: aba bathandayo bomculo baxilongwa ngokunyuka ngokukhawuleza kwintetho, eyayiyimpawu kuphela yabantu abadala. Nangona utshintsho olunexesha elidala lokuvalelwa luqala emva kwemashumi amathathu kuphela, ukuhlaselwa okusisigxina okuqhubekayo kuhlaziya kwakhona le nqondiso. Iingcali zithi le nto "ebomini kwi-headphones" kunye nothando lweengxoxo zomsindo. Iintlanzi zixhaphake kakhulu kubantu basezidolophini kunabemi basekhaya - emva koko, isixeko sizaliswe ngomsindo. " Ingaba imbono yeendlebe ezahlukeneyo ziyabhubhisa?
Zonke iintlobo zengxolo kunye nokuqonda kweendlebe zezandi ezahlukileyo kwaye zithathwa ngendlebe ngeendlela ezahlukeneyo. Ukubetha iinyoni, amaza aphuma, ii-piano chords zichaphazela ngokupheleleyo i-psyche kwaye ayiyi kutshabalalisa indlebe. Enye into izandi zentlalo, nokuba yinto yokusebenza, ingxolo yombane okanye umculo owenziweyo osulela kwiithethi okanye kwi-headphone. Ukwahlula phakathi kweqela lokuqala kunye neyesibini kubudeni kunye nobuchule besandi. Ezi zimbini zibonakalisa nayiphi na isignali yesandi.
Izandi eziphakamileyo ezibizwa ngokuba yi-"infrasound", izandi ezisezantsi zibizwa ngokuthi "i-ultrasound." Iimfono eziphantsi ngokugqithiseleyo ziphazamisa ingxaki ye-psyche, kubangela iziphazamiso zesifo, ukuphazamiseka kweentlanzi, kwaye kwanokubangela ukuhluleka kwentliziyo. Olunye uhlobo olugqithiseleyo lukhulu kakhulu. Ziyabonwa njengababhubhisi abaziintloko beentlebe - ziphazamisa i-nervitive nerve kwaye zibangele ukufa kwazo. Ukuba iindlebe zihlaselwa ngamaqondo aphezulu imihla ngemihla, umntu ulahlekelwa ngokukhawuleza ukuva. I-insidi eyona nto kukuba iimbilini ze-nerve ziyafa ngokupheleleyo, kwaye isiphumo sisithulu.
Wonke umntu ophilileyo uyaziqonda ngeendlebe zakhe izandi ezahlukeneyo kunye nemisindo. Yintoni eqhelekileyo yomsindo wezwi? Kukholelwa ukuba inqanaba eliphantsi kakhulu lezandi elibanjwe kwindlebe enempilo ngu-10-15 dB. I-Whisper - 20 dB, intetho yokudibanisa - 30-40 dB. Ukumemeza kuqikelelwa kwi-60 dB kwaye sele sele ikhululekile kwiindlebe, kodwa i-90 dB izandile ngokukhawuleza inkunkuma yokunceda. Yintoni esinokuyithetha ngamakhonsathi kunye neeklabhu, apho i-bill bill iya kumakhulu e-decibel. Akumangalisi ukuba ukulahlekelwa kwindlebe kuthathwa njengesifo sobuchwephesha beemvumi zengoma kunye nee-DJs. Abadlali abathandekayo, njengomthetho, phulaphula ngokuvakalayo ubuncinane be-70 dB. Kwaye i-pleyromany enamandla iyazi: ngokuvakala komculo okwexesha elide, ngokukhawuleza kukho umnqweno wokongeza ilizwi, ngokuphindaphindiweyo ... Ngokuhamba kwexesha, i "dose" enkulu yesandi iyadingeka. Okungathandekiyo, indlebe iyavumelana nayo kwaye iyayiqonda njengesiqhelo. Ngelishwa, akukho nto iqhelekileyo.
Enye ingozi yomdlali kukuba indlela yokuva kunye neendlebe zezandi ezahlukahlukeneyo ngokusebenzisa i-headphone akunjalo ngokungekho mvelaphi kumntu. Ngokufanelekileyo, iindlebe zibona izandi ezahlukileyo kwi-canal yokucwaninga, umqondiso uhlahlela i-eardrum, uguqulwa ube yi-vibrations, kwaye udluliselwe kwi-cochlea ehleli kwiindlebe zangaphakathi. Kuyo, iguqula ibe yimpembelelo yentsholongwane ize iqondwe ngqondweni. Kwaye ukuba isandi somsindo sihlala sisasazeka emoyeni, ngoko, ngokusebenzisa i-headphones, liza ngqo kwi-ossicle yokuphicotha kwaye ihambela indlebe yangaphakathi ngangokunokwenzeka. Isenzo esinjalo esinobudlova sibangela ukuvuvukala, kunye nokufa kwesigidi sokuhlola. Okuyingozi kakhulu kukudlulela komdlali kubantwana nakwishumi elivisayo-abathengi abakhulu bemimandla enkulu. Ayisongelo nje ngokunciphisa ukuva, kodwa inokuphelisa nomculo. Ngenxa yokulahlekelwa kwintlanganiso yokuqala, abantwana abayi kukwazi ukwahlula imiba yezinto zokuvakala nokuphuhlisa indlebe yomculo.
Dlala ukhuseleko
Abaninzi "bahleli kumdlali" bayazi-ukushiya umdlalo ozithandayo akulula. Ukuqhekeza kwangempela-kuqala-ndiyathanda kakhulu ukucima iindlebe zam kwaye ndiqhubeke kwihlabathi lomculo ozithandayo. Ingaba njani - indlela yokusebenza, ukugijima, ukuqeqeshwa kwindawo yokuzivocavoca - kwaye konke oku ngaphandle komculo? Ngaphandle kwenkathazo, ingqungquthela phakathi kweendlebe kunye nommangaliso onokuthwala unokwenzeka. Kufuneka kuphela ukuqwalasela ezinye iingongoma: lungisa utshintsho lwesandi. Phantse yonke imodeli yomdlali inokulinganisela, ngoncedo apho ungasetha khona imvama ekhuselekileyo indlebe. Ngaphezu koko, abanye abavelisi baxhobisa iimveliso zabo kunye nomsebenzi wokhuseleko olukhuselekileyo, owenza ngokuzenzekelayo udidi lwezakhono. Ukuba akwenzi, nceda uqaphele ukuba umthamo okhuselekileyo ungama-60% ophezulu.
Khetha i "headphone" ephathekayo . Kwikhwalithi akuyimfuneko ukuyigcina - ayixhomekeke ekuhlambulukeni kwesandi, kodwa nakwimpilo yakho. Ngoko ke, xa ukhetha "iindlebe" kubhekisela kwiimpawu ezidumileyo. Kodwa umgangatho ophezulu kuphela awukho isiqinisekiso sokhuseleko olupheleleyo. Kubaluleke kakhulu uhlobo lwee headphone. Amathebhu amancinci athatyathwa ngqo kwiindlebe ngokuqinisekileyo akhululekile, kodwa ayingozi kwindlebe. I-apotheosis yokunciphisa ubunzima kunye neengozi yi-headphone, ezifakela iindlebe zazo njengeeplagi. Emva koko ilungu lokuphulaphula liphela ngokupheleleyo kwilizwe langaphandle, kwaye isandi esinamandla sijoliswe ngqo kwiindlebe zangaphakathi. Ngako oko, kungcono ukhethe i-headphones ngendlela yobuncwane, obungayeki iindlebe kwaye unikezele ukungena kwesandi. Ixesha lokubetha. Iyakwazi ukuhluka ngokuxhomekeke kwiminyaka yobudala, impilo, imisebenzi ethile kunye nokuphakama. Kwixesha elikhuselekileyo, ngeefowuni ezifanelekileyo kunye nekhnoloji yekhwalithi ephakamileyo, unokukwazi ukufumana umxhelo owodwa-iiyure ezimbini zomculo ozithandayo. Ngokukhawuleza isandi, ixesha elincinane lokuphulaphula. Cingisisa imeko yezempilo. Nezinye izifo - neuritis, vegetosusosudistoy dystonia, utywala, umfutho wegazi ophezulu, umdlalo onjengomdlali, unokudambisa imeko yezempilo.
Ndifanele nini ukunciphisa isandi kwaye ndibuyele ku-LOR?
Ngeentloko ezikhishiwe, uthetha ngamathoni aphakamileyo okanye ucele abanye ukuba bakhulume kakhulu. Uhlala utyunjwa, bathi, kutheni bekhala. Udla uvakalelwa kukuba "ukukhala" ezindlebeni (tinnitus). Ukuba ibonakala, umzimba uyawubetha i-alamu - ncinane kwaye izithulu ziya kuqala. Izinto eziphazamisayo zingabangela ukuba utyhefu.
