Hearing loss can be subtle and may creep up on you without you noticing. You might find yourself turning up the TV or reading the lips of people who are talking to you, in order to compensate. But, if left alone, the problem can worsen, so it’s always best to have it checked out as soon as you notice any deterioration. Experts recommend this is done on at least an annual basis, just as you would with going to the optician or dentist.
