Kodi alamu ya munthu ndi DB zingati?

M'dziko lamakono, chitetezo cha munthu payekha ndiye chinthu chofunika kwambiri kwa aliyense. Kaya mukuyenda nokha usiku, kupita kumalo osazolowereka, kapena mukufuna mtendere wamumtima, kukhala ndi chida chodalirika chodzitetezera ndikofunikira. Apa ndi pomweChingwe Chosungira Alamu Chaumwiniimabwera, ikupereka yankho laling'ono komanso lamphamvu kuti likuthandizeni kukhala otetezeka mulimonse momwe zinthu zilili. Limodzi mwa mafunso ofala kwambiri okhudza makiyi a alamu yaumwini ndi lakuti "Kodi mulingo wa decibel wa alamu yaumwini ndi wotani?" Yankho limasiyana malinga ndi mtundu wake, koma ambirima alamu aumwinilimatulutsa phokoso la pakati pa 120 ndi 130 decibels. Mlingo uwu wa phokoso ndi wofanana ndi phokoso la injini ya ndege yomwe ikuyamba ndipo ndi wokwanira kukopa chidwi ndikuletsa zoopsa zomwe zingachitike.

 

Makiyi a alamu a munthu payekha amapangidwira kuti azitha kuwafikira mosavuta akafunika. Ndi kukoka kapena kukanikiza batani, siren imatulutsa phokoso loopsa lomwe lingawopseze owukira ndikuchenjeza anthu omwe ali pafupi za mavuto anu. Kuyang'aniridwa mwachangu kumeneku kungakupatseni nthawi yamtengo wapatali yomwe mukufuna kuti muthawe zoopsa ndikupempha thandizo.

Kuwonjezera pa phokoso lapamwamba kwambiri, makiyi ambiri a alamu amabwera ndi zinthu zina monga tochi ya LED yomangidwa mkati, zomwe zimapangitsa kuti ikhale chida chogwiritsidwa ntchito pazochitika zosiyanasiyana. Kaya mukufufuza makiyi anu mumdima kapena mukufuna thandizo, zowonjezera zatsopanozi zingakuthandizeni kukhala otetezeka.

Kuphatikiza apo, makiyi a alamu nthawi zambiri amapangidwa ngati zowonjezera zosaoneka bwino komanso zokongola, zomwe zimapangitsa kuti zikhale zosavuta kunyamula ndikuphatikizana ndi moyo wanu watsiku ndi tsiku. Kukula kwawo kochepa komanso kupepuka kumakupatsani mwayi wowalumikiza ku makiyi anu, chikwama, kapena thumba lanu, zomwe zimakutsimikizirani kuti nthawi zonse mumakhala ndi chida chodzitetezera chodalirika.

 

Mwachidule, fob ya alamu yaumwini ndi yowonjezera pa chitetezo chilichonse chaumwini. Phokoso lawo la decibel yokwera, kugwiritsa ntchito mosavuta, komanso kugwiritsa ntchito bwino kumapangitsa kuti ikhale yankho lothandiza komanso losavuta lodziteteza. Mwa kuyika fob ya alamu yaumwini pa moyo wanu watsiku ndi tsiku, mutha kuchitapo kanthu mwachangu kuti muwonjezere chitetezo chanu komanso mtendere wamumtima.
