Have you noticed a ringing sound in your ears lately, or found it hard to hear others clearly? Have you been casually brushing it off as just getting older?

When talking with your parents, do you often hear them say, 'What?' or 'Can you say that again?' The conversation keeps breaking off, your parents feel upset about missing important details, and you end up raising your voice. It hurts your heart too much to simply brush it off with, 'It's just because they are getting older.'
