Ukulahleka kokuzwa nomculo

Abantu abadala nezingane bavame ukuchayeka emculweni onomsindo. Ukulalela umculo ophakeme ngezindlebe ezixhunywe kumadivayisi afana ne-iPods noma ama-MP3 player noma kumakhonsathi omculo kungadala ukulahlekelwa ukuzwa.

Ingxenye engaphakathi yendlebe iqukethe amangqamuzana amancane ezinwele (iziphetho zezinzwa).

• Amaseli ezinwele aguqula umsindo uwenze amasignali kagesi.
• Izinzwa bese zihambisa lezi zimpawu ziye ebuchosheni, obubona njengomsindo.
• La maseli amancane ezinwele alinyazwa kalula yimisindo ephezulu.

Indlebe yomuntu ifana nanoma yisiphi esinye isitho somzimba - ukusetshenziswa kakhulu kungayilimaza.

Ngokuhamba kwesikhathi, ukuvezwa okuphindaphindwayo ngomsindo omkhulu nomculo kungadala ukulahleka kokuzwa.

I-decibel (dB) iyunithi yokukala izinga lomsindo.

• Umsindo othambile ongalezwa abanye abantu ungama-20 dB noma ngaphansi.
• Ukukhuluma okujwayelekile kungu-40 dB kuye ku-60 dB.
• Ikhonsathi ye-rock iphakathi kuka-80 dB no-120 dB futhi ingaba phezulu njenge-140 dB phambi kwezipikha.
• Amahedfoni ngevolumu ephezulu acishe abe yi-105 dB.

Ingozi yokonakala ezindlebeni zakho lapho ulalele umculo incike kulokhu:

• Ukhala kangakanani umculo
• Ungasondelana kanjani nezikhulumi
• Uvezwa isikhathi esingakanani futhi kangaki emculweni onomsindo
• Ukusetshenziswa kwehedfoni bese uthayipha
• Umlando womndeni wokulahleka kokuzwa

Imisebenzi noma imisebenzi ekhulisa amathuba akho okulahleka kokuzwa emculweni yile:

• Ukuba ngumculi, ilungu lezisebenzi ezinomsindo, noma unjiniyela wokurekhoda
• Ukusebenza ekilabhini yasebusuku
• Ukuhambela amakhonsathi
• Kusetshenziswa amadivayisi omculo aphathekayo anamahedfoni noma izindlebe

Izingane ezidlala emaqenjini esikole zingavezwa imisindo ephezulu ye-decibel, kuya ngokuthi iziphi izinsimbi ezihlala eduze noma ezizidlalayo.

Ama-napkin noma izicubu ezigoqiwe azenzi lutho ukuvikela izindlebe zakho emakhonsathini.

Izinhlobo ezimbili zama-earplugs ziyatholakala ukugqoka:

• Ama-earplugs amagwebu noma abicah, atholakala ezitolo zezidakamizwa, asiza ukunciphisa umsindo. Zizokhipha imisindo namaphimbo kepha zingalingana kahle.
• Ama-earplugs womculo owenziwe ngokwezifiso alingana kangcono kunamagwebu noma awabicah futhi awashintshi ikhwalithi yomsindo.

Amanye amathiphu ngenkathi usezindaweni zomculo yilena:

• Hlala okungenani amamitha ama-3 noma ngaphezulu kude nezipika
• Thatha amakhefu ezindaweni ezithulile. Nciphisa isikhathi sakho ngomsindo.
• Zulazula endaweni ukuze uthole indawo ethulile.
• Gwema ukuthi abanye bamemeze ezindlebeni zakho ukuze uzwakale. Lokhu kungadala ukulimala okuqhubekayo ezindlebeni zakho.
• Gwema utshwala obuningi, obungenza ungazi imisindo ephezulu yezinhlungu engayibanga.

Phumuza izindlebe zakho amahora angama-24 ngemuva kokuchayeka emculweni onomsindo ukuze ubanikeze ithuba lokululama.

Ama-headphone wesitayela se-bud bud (afakwa ezindlebeni) awavimbi imisindo yangaphandle. Abasebenzisi bavame ukukhuphula ivolumu ukuvimba omunye umsindo. Ukusebenzisa ama-earphone okukhansela umsindo kungakusiza wehlise ivolumu ngoba ungawuzwa kalula umculo.

Uma ufaka ama-headphone, ivolumu inkulu kakhulu uma umuntu emi eduze kwakho ungawuzwa umculo ngama-headphone akho.

Amanye amathiphu mayelana namahedfoni yilawa:

• Nciphisa isikhathi osisebenzisa ngaso i-headphone.
• Yehlisa ivolumu. Ukulalela umculo ezingeni lesi-5 noma ngaphezulu imizuzu eyi-15 ngosuku kungadala ukulimala kokuzwa kwesikhathi eside.
• Unganyusi ivolumu udlule iphuzu maphakathi kubha yevolumu lapho usebenzisa amahedfoni. Noma, sebenzisa umkhawulo wevolumu kudivayisi yakho. Lokhu kuzokuvimbela ekuguquleni umsindo uphezulu kakhulu.

Uma kukhala ezindlebeni zakho noma ukuzwa kwakho kungashaywanga amahora angaphezu kwama-24 ngemuva kokuchayeka emculweni onomsindo, yenza ukuthi ukuzwa kwakho kuhlolwe ngudokotela wezwi.

Bheka umhlinzeki wakho wezokunakekelwa kwempilo ukuze uthole izimpawu zokulahlekelwa ukuzwa uma:

• Eminye imisindo ibonakala iphakeme kakhulu kunalokho okufanele ngabe iyikho.
• Kulula ukuzwa amazwi abesilisa kunamazwi abesifazane.
• Unenkinga yokutshela imisindo ephezulu (njenge "s" noma "th") komunye nomunye.
• Amazwi abanye abantu azwakala ekhungathekile noma edidekile.
• Udinga ukuvula phezulu ithelevishini noma umsakazo.
• Unokukhala noma umuzwa ogcwele ezindlebeni zakho.

Umsindo odalelwe ukulahleka kokuzwa - umculo; Ukulahlekelwa kokuzwa okuzwayo - umculo
