• A túa audición cambiou de súpeto nos últimos 6 meses.

Algunhas persoas con perda auditiva poden necesitar axuda dun profesional da saúde auditiva.
Como sabes se necesitas ver un?

• You can't hear speech even if the room is quiet.
• You don't hear loud sounds well, for example, you don't hear loud music, power tools, engines, or other very noisy things.

Se a túa perda auditiva dificulta escoitar ruídos fortes, é posible que este audiófono non sexa a túa mellor opción sen a axuda dun profesional. Se este audífono non che axuda o suficiente, pide axuda a un audioprotesista.
