Batire yamutu wakugona

Chomverera m'makutu ndi chipangizo chomwe chimavalidwa pamutu kuti chiziyimba molunjika m'makutu. Zidazi zimagwiritsidwa ntchito ndi osewera amtundu wa iphone mp3, komanso zitha kugulidwa ngati zinthu zodziyimira pawokha. Kafukufuku adasindikizidwa mu Journal of American Medical Association pa November 2006 kukambirana za nthawi yayitali kuti anthu ovala makutu ogona agone, ngati akugona mofulumira, kugona nkomwe.

Kafukufukuyu akumaliza kuti palibe kulumikizana pakati pa mahedifoni ndi kugona mwachangu kapena kosavuta. Pali maphunziro angapo omwe akutuluka tsopano akupeza kuti zomverera zogona izi zimapereka maubwino ena monga kutsekereza phokoso lachilengedwe lomwe lingayambitse kuwongolera kwa kugona komanso kuchuluka kwamphamvu masana.

Zikuwoneka kuti pali mitundu iwiri ya maphunziro malinga ndi kafukufukuyu. Gulu loyamba ndi la anthu 24 omwe anatha kuvala mahedifoni awa ndikugona nawo, ndipo gulu lachiwiri linali la anthu 20 omwe sankatha kugona ndi mahedifoni.

Ofufuzawa adapeza kuti panalibe kusiyana kwakukulu kwa zaka, jenda kapena BMI pakati pa magulu awiriwa. Chodziwika chokha pakati pa magulu onsewa chinali chakuti onse anali ndi kumva bwino ndipo palibe amene amavala chigoba pogona. Izi zikutanthauza kuti sizingatheke kuti mutha kugwiritsa ntchito bwino mutu wakugona ngati mulibe kumva bwino komanso/kapena mumagwiritsa ntchito kale chigoba chogona. Ngati ndi choncho, musataye mtima chifukwa pali njira zina zingapo zomwe zilipo monga kugwiritsa ntchito matiresi makamaka poletsa mawu, makina oyera a phokoso, zotsekera m'makutu, ndi zina zambiri ...

Kafukufuku wambiri wachitikanso okhudza zotsatira za nyimbo zaphokoso pamagonedwe. Iwo anapeza kuti kuimba nyimbo kwa usiku wonse sikunalepheretse anthu kugona; komabe zidawapangitsa kudzuka kuwirikiza kanayi kuposa momwe amakhalira. Ndipo ngakhale kuti nyimbo zaphokoso sizimakulepheretsani kugona, zingapangitse kugona kwanu kukhala koipitsitsa kwambiri mwa kuwonjezera maulendo odzuka ndi kuchepetsa kugona. Kuwonongeka kwa kugona kumeneku kunali kokulirapo pomvetsera voliyumu mokweza kwambiri (ma decibel 4). Kafukufuku yemwe adachitika adatsimikiza kuti kusewera nyimbo kumatha kukulepheretsani kuti mubwererenso kukagona mwachangu ngati mutadzutsidwa panthawi inayake chifukwa kumasintha kugona kwachilengedwe.

Ngati muli ngati ine ndipo mumadziona kuti ndinu wofunitsitsa kudziwa m'mbali zonse za moyo, mwina mukuganiza kuti ndi mtundu wanji wa voliyumu womwe ungaganizidwe kuti ndi wotetezeka kugwiritsa ntchito ndi chomverera m'makutu. Chabwino yankho ndi 80 decibels kapena kuchepera.

Voliyumu ya 80 dB imatengedwa kuti ndi yotsika kotero palibe chifukwa chokhalira ndi MP3 player pa kuphulika kwathunthu pamene mukuyesera kugona. Ngati muli ndi chigoba chogona, ndibwino kuti mugwiritse ntchito mtundu wamutu wamtundu wotsegula kuti mafunde a phokoso azitha kuyenda mosavuta kuchokera ku khutu lanu kupita ku khutu lanu lamkati. Ndi mtundu wamtundu wa makutu otsekedwa, phokoso limatsekedwa likafika potsegula khutu ndipo chifukwa palibe njira yoti mamvekedwe alowe m'khutu la m'makutu, ayenera kukulitsidwa kuti akuthandizeni; monga womvera; kuwamva iwo.

Chinthu chotsiriza chimene ndikufuna kunena ndi chakuti ngakhale ma headsets sangapangitse kugona kosavuta kapena mofulumira, amapereka zopindulitsa zina monga kutsekereza phokoso la chilengedwe lomwe lingapangitse ubwino wa kugona komanso kuwonjezeka kwa mphamvu masana.

Ndithudi ife tonse tikudziwa; kapena osachepera tiyenera kudziwa; kuti pamafunika awiri ku tango kutanthauza kuti chifukwa chakuti mwavala chomverera m’makutu ndi kuimba nyimbo zachete, sizitanthauza kuti mkazi wanu adzachitanso chimodzimodzi. Angakhale akuimba nyimbo zomwe amakonda mokweza monga momwe angathere pa foni yake popanda mahedifoni zomwe zingapangitse kugona ndi chomverera m'makutu kukhala chosatheka kwa nonse pokhapokha mutakhala ndi zipinda zosiyana.

Mfundo yaikulu ndi iyi:

Ngati mumatha kugona mutavala mahedifoni, palibe umboni wosonyeza kuti amatha kuteteza kapena kuyambitsa kusowa tulo kapena kugona. Chofunika kukumbukira apa, komabe, ndi chakuti thupi lanu likhoza kutenga nthawi yaitali kuti lizolowere ngati mwadzidzidzi mutayamba kugwiritsa ntchito mahedifoniwa m'malo mwa makutu kapena mankhwala ogulitsira. Ngati muli ndi vuto la kugona, ndi bwino kuyamba ndi mawu ochepa ndikuwona zomwe zimachitika. Palibe kukayika kuti pali ubwino wambiri wogwiritsa ntchito mutu wakugona ndipo ngati wachita bwino; ngakhale popanda kuimba nyimbo; Angathebe kulimbikitsa kugona bwino mwa kutsekereza phokoso lozungulira ndi ma frequency osokoneza.
