An overproduction of ear wax or a build up of debris in the ear canal can lead to a reduction in hearing or a feeling of dull hearing.
If you find your hearing becoming dull, it pays to book a free hearing check at your local Triton Hearing Clinic. Triton Hearing no longer offer ear wax removal via micro-suctioning but can refer you to a local provider.
It may also be as a result of excess ear wax or other debris in the ear canal. Over time, the narrow, curved ear canal can become blocked with wax, skin or debris.
