Zviri pachena kuti vabereki vanowanzowedzeredza pavanenge vachiudza vana vavo nezvezvinetso zvoutano zvinogona kuitika pamusana pokushandisa midziyo yemagetsi. Asi njodzi yekurasikirwa nekunzwa kwako nekuda kwemimhanzi ine ruzha iri kure nekufungidzira. Ingotarisa vanhu vanopfuura makumi mana vanoshanda mumafekitori kana munhandare dzendege. Pamazinga enzwi ari pamusoro pe40 dB, kunzwa kunokanganiswa. Kunyange kuwedzera kumwe chete kunokanganisa nhengo dzekunzwa. Uye chii chinoitika kumatare enzeve apo iwo anopiwa ruzha rukuru zuva nezuva?
"Kuteerera kwakachengeteka" mutemo chinhu chitsva munyika yezvigadzirwa
WHO (World Health Organisation) inofungidzira kuti vanhu vanosvika mamiriyoni mazana mana vane makore anopfuura makumi mana pasi rose vatova nematambudziko ekunzwa. Zvidzidzo zvakaratidza kuti mahedhifoni akajairwa akave manyuko ekuremara. Zvakaonekwa kuti pavhoriyamu yepakati, yakavharwa-kumashure mahedhifoni uye earbuds inopa kunze 400-40 dB. Pahuwandu hwehuwandu - 102 dB uye pamusoro. Chimiro chevakuru ivhoriyamu inosvika 108 dB, yevana - kusvika 112 dB.
Pakazara, masayendisiti akaita zvidzidzo makumi matatu neshanu munyika dzakasiyana dzepasi. Vakapindwa nevanhu 35 20 vane makore gumi nemaviri kusvika makumi matatu nemashanu. Mukuwedzera pakuteerera mimhanzi pamahedhifoni, “varwere” vakashanyira nzvimbo dzevaraidzo uko mimhanzi yairidzwa zvine ruzha. Kunyanya, makirabhu ekutamba. Vose vatori vechikamu, mumwe nomumwe nenzira yavo, vakagamuchira kukuvara kwekunzwa.
Zvichienderana netsvagiridzo iyi, masayendisiti akaenda kuWHO aine kurudziro yekuunza mutemo we "kuteerera kwakachengeteka". Inosanganisira kudzikamisa simba remahedhifoni. Sezvingatarisirwa, izvi zvinonyanya kutariswa pane zvinodiwa kune vanogadzira.
Maererano nenyanzvi dzinoshanda mumunda weTI tekinoroji, kukwidza kwakadaro hakugone kuwana rutsigiro pakati pezviremera kana vagadziri. Mushure mezvose, zvinokanganisa zvishuwo zvakawanda zvemari panguva imwe chete:
- Kuderera mukukwezva kwechigadzirwa nekuda kwesimba risingatarisirwi.
- Mutengo wekuronga marabhoritari kuti uone zvakaziviswa hunhu hwemahedhifoni.
- Kurasikirwa nemari yemasangano ekurapa (vanachiremba nevagadziri vezvibatsiro zvekunzwa).
Zvinoitika kuti "ruponeso rwekunyura ibasa rekunyura ivo pachavo." Ndiko kuti, munhu mumwe nomumwe anofanira kunzwisisa mhedzisiro yemamiriro ezvinhu aripo. Uye ita chiito iwe pachako. Asi hazvibviri kuti vechidiki vachateerera mimhanzi nezwi rakaderera. Uye mazano evabereki atova munhu mukuru, apo matambudziko aya akatoonekwa. Uye saka tinosvika kune kunobva kuwedzeredza kwezvinetso zvevabereki vari kuedza kufunga nevana vavo.
