Hearing test (audiometry)

Why do I need to have this test?

Some chemotherapy drugs, such as cisplatin, and radiotherapy to the head can affect your hearing. You may have a hearing test before, during and after treatment. A hearing test is called an audiometry.

What happens?

The test may take up to an hour. It will be done by an audiologist. First, they check your ears for any blockages such as ear wax. After this, they give you headphones to wear and test your ears one at a time. They play sounds at different volumes and pitches. You will be asked to press a button on a device each time you hear a sound. The sounds gradually get quieter. Sometimes they also play words and ask you to repeat back what you hear.

Always tell your doctor or nurse if you notice any changes in your hearing.
