Assistive listening device

Igikoresho gifasha kumva (ALD) ni igice cya sisitemu ikoreshwa mugutezimbere ubushobozi bwo kumva k'ubantu mubihe bitandukanye aho badashobora gutandukanya imvugo ahantu huzuye urusaku. Akenshi, mucyumba gisakuza cyangwa cyuzuye abantu ntibishoboka ko umuntu ku giti cye ufite ubumuga bwo kutumva gutandukanya ijwi rimwe muri benshi. Ibi bikunze kwiyongera n'ingaruka za acoustique yo mucyumba kumiterere yimvugo igaragara. Imfashanyigisho zumva zishobora kwagura no gutunganya aya majwi, no kunoza imvugo ku kigereranyo cy’urusaku . Ariko, niba ijwi ryagoretse cyane mugihe rigeze kubateze amatwi, ndetse n'ibikoresho byiza byumvikana bizarwanira gukuraho ibimenyetso. Ibikoresho bifasha gutega amatwi bitanga ubundi buryo bwo guhuza n'imihindagurikire y'ikirere, ariko birashobora kuba bigoye kandi bitoroshye.

 Ikoreshwa 
Ikoreshwa rusange mu gufasha abantu bigoye kumva (HOH) mukongera imbaraga no gutanga ibimenyetso byiza kubigereranyo by'urusaku (SNR). ALD irashobora gukoreshwa mu gufasha abantu HOH kumva televiziyo  n'ibindi ikoresho by'amajwi,  cyangwa gufasha abantu kumva imvugo binyuze muri aderesi rusange cyangwa sisitemu yo gushimangira amajwi, nko ahantu ho gusengera cyangwa gutanga ibiganiro.

Gukoresha mikoro idafite umugozi ishyizwe iruhande rw'umuntu uvuga ikuraho amajwi hagati yabo n'uwumva, ibyo bikaba bigabanya ingaruka zo kwisubiramo biturutse kuri acoustics yo mucyumba kibi, urusaku rw'inyuma ruzenguruka abumva, hamwe n'urusaku rw'inyuma ruzenguruka umuvugizi (ukoresheje mikoro yerekeza) . 

 Ikoranabuhanga 
Igikoresho gifasha kumva gikunze gukoresha mikoro kugirango ifate isoko y'amajwi hafi y'inkomoko yayo kandi ikayitambutsa mu buryo butemewe hakoreshejwe uburyo bwo guhinduranya inshuro (FM), infragre (IR), loop induction, cyangwa ubundi buryo. Umuntu uri gutega amatwi arashobora gukoresha inyakiramajwi idafite umugozi kugirango ahuze ibimenyetso kandi yumve amajwi akunda. Hariiho kandi n'abandi baguzi ALDs nk'amasaha yo gutabaza hamwe no kunyeganyeza uburiri, stethoscopes yongerewe imbaraga, monitor y'abana, hamwe n'ibimenyetso byerekana inzogera z'umuryango.  Ibikoresho byinshi bifasha kumva neza FM bikorera kumirongo cumi n'irindwi hagati ya 72.1000 na 75.800MHz.
