La tecnologia en el sector de l’ audiologia s’ ha millorat molt en els darrers anys avui dia els audi\u00f2fons digitals ajuden a entendre millor en les diverses situacions sonores en les quals estem exposat.<\/p>\n

Els audi\u00f2fons Digitals avui dia s\u00f3n capa\u00e7os de comparar diversos tipus de sons, sobretot parlem del soroll respecte a la paraula, considerant el soroll com un so residual i la paraula com un so modular i harm\u00f2nic.<\/p>\n

Podem explicar el funcionament dels audi\u00f2fons digitals, per nivells sonors, canals o particions freq\u00fc\u00e8ncies.<\/p>\n

0-30 dB el considerem com el primer nivell sonor, equival als sons suaus, com el ventilador d’ un ordinador, el lliscament d’ un llapis sobre un paper, etc<\/p>\n

30 a 45\/50 dB el considerem com el segon nivell sonor, equival al nivell d’amplificaci\u00f3 de la veu humana sense for\u00e7ar-la o elevar-la.<\/p>\n

45\/50 dB a 80\/90dB el considerem com el tercer nivell sonor, equival als sons forts o elevats.<\/p>\n

80\/90dB a 120\/130dB el considerem com el quart nivell sonor, els audi\u00f2fons es limiten segons el llindar de sensibilitat m\u00e0xima de percepci\u00f3 del so. Un audi\u00f2fon a m\u00e9s d’ amplificar el so ha de protegir l’ o\u00efda per no perjudicar-lo. \u00c9s un producte m\u00e8dic que ha passat pel departament d’autoritzaci\u00f3 de Sanitat.<\/p>\n

D’altra banda tenim els canals. Una o\u00efda humana sa \u00e9s capa\u00e7 d’ identificar freq\u00fc\u00e8ncies des de 125 HZ fins a 12000Hz, tenint en compte que l’ ample de banda frecu\u00e8ncial on hi ha la m\u00e0xima informaci\u00f3 de la veu humana correspon a les freq\u00fc\u00e8ncies que van des dels 250 Hz fins a 6000Hz. Per tant els canals s\u00f3n les particions per freq\u00fc\u00e8ncies des dels 125Hz fins a 12000Hz.<\/p>\n","protected":false},"excerpt":{"rendered":"
