What does asymmetrical hearing loss mean?

Asymmetrical hearing loss describes a meaningful difference in hearing between your two ears. Rather than both ears changing together, one ear performs noticeably worse than the other. Audiologists take this pattern seriously because, while it is often harmless, it can sometimes point to a cause worth investigating.

How is asymmetrical hearing loss different from the usual pattern?

Age-related and noise-related hearing changes tend to be fairly symmetrical, affecting both ears in a similar way. When one ear is clearly different, that stands out on a hearing test. Your audiologist looks at the results for each ear side by side and measures the gap between them across different pitches to decide whether the difference is significant.

What can cause one ear to hear differently?

There are many possible reasons, ranging from very common and minor to less common. These may include:

• Earwax build-up or a blockage in one ear
• A past or current ear infection on one side
• Noise exposure that affected one ear more, such as shooting or certain machinery
• A previous injury or perforated eardrum
• Natural variation that has simply become more noticeable over time

Less commonly, an asymmetry can be associated with other conditions affecting the hearing nerve. This is one reason audiologists generally suggest that a new or unexplained difference between the ears be reviewed reasonably promptly, so the cause can be understood rather than assumed.

What signs might suggest asymmetrical hearing loss?

You might notice you prefer holding the phone to one ear, that voices sound clearer on one side, or that you turn a particular ear towards a speaker. Some people also experience ringing (tinnitus) or a feeling of fullness in the poorer-hearing ear. These observations are useful to share at your appointment.

How is it assessed and managed?

A standard hearing assessment tests each ear separately, so an asymmetry usually shows up clearly. Depending on what the audiologist finds, they may recommend further checks or refer you to your GP or a specialist for additional investigation. If a medical cause is identified, that can be addressed on its own path.

Where the difference is ongoing, there are practical ways to help. Options may include a hearing aid for the affected ear, or specialised solutions designed to route sound from the poorer side to the better-hearing ear so conversations feel more balanced. The most suitable approach depends on your individual results and lifestyle.

It also helps to keep a few practical points in mind. A one-off blocked feeling after a cold or a flight is usually nothing to worry about and often settles on its own. A difference between the ears that persists, gradually worsens, or comes with tinnitus, dizziness, or discharge is more of a reason to be assessed. Noting when you first noticed it, whether it is steady or changing, and any related symptoms gives the audiologist valuable clues. There is no need to self-diagnose from this information — its purpose is simply to help you decide when a check is worthwhile.

If you have noticed one ear is not hearing as well as the other, it is worth having it checked rather than waiting. At Hearing Help in Newport Marketplace on the Redcliffe Peninsula, a qualified audiologist can assess each ear, explain the difference in plain terms, and discuss what may help. No referral is needed to book an assessment.
