Gradual Hearing Loss: Why Is It Often Overlooked

Many older adults are surprised to learn that their hearing has changed, even though the process has been happening slowly over several months or years. This is because gradual hearing loss happens so subtly, it can be difficult to recognize at first. The brain naturally adjusts to small shifts in sound, making it easy to overlook early signs.

For instance, you might start increasing the television volume a little at a time or ask others to repeat themselves more often without realizing it has become a habit. In many cases, a friend or family member is the first to notice these changes.

In a study that looked at hearing loss among people in Canada between the ages of 40 and 79, 8% of men and 5% of women self-reported hearing impairment. But when researchers measured the hearing of participants, they found that 63% of men and 46% of women had measurable hearing loss.

One key reason gradual hearing loss is hard to notice is that your brain adapts to small changes over time. You may find yourself filling in missing words or guessing what someone said, which can make it seem like you are still hearing well even when you are missing certain sounds.

Scheduling routine hearing tests allows audiologists to track your hearing over time and detect gradual changes early. Taking steps now supports your hearing health for years to come.
