The Association of Independent Hearing Professionals have suggested regular hearing checkups as follows:

18 to 45 years of age: Every five years
45 to 60 years of age: Every three years
Over 60 years of age: Every two years

Hearing loss can be gradual, and you may become accustomed to some degree of hearing loss before it becomes a significant impediment. A regularly scheduled hearing and ear test can detect problems early and get you the treatment you need. 

• Do you find yourself asking people to repeat themselves?
• Do you have difficulty in public places such as restaurants, church, meetings, etc.?
• Does your family complain that the TV is too loud?
• Do certain voices (women, children) cause you more difficulty?
• Do you have a history of being in or around a noisy environment?
• Does one ear perform better than the other?
• Do you suffer from tinnitus (ringing or roaring of the ears)?
• Did you suddenly lose your hearing?

If you experience any of these problems, it may be time to have your hearing checked.
