Well, let's try again.
Open Health app on the phone and be onthe Summary Page. Then scroll down until you see Hearing Test Results. if you cannot see it with the things you have pinned, then scroll a little further until you see Show All Health Data. Then you should be able to find that in the list, tap on it.

Tap on the test that appears there and then skip over Show More Data and scroll down to Show All Data.


Then you should see a list of Hearing Test Results. You can tap Edit in the upper right corner, then you can tap on the red dot with the minus sign, or swipe to the left and the Delete should appear. Also, once you hit edit, if you have more test results showing there, the Delete All command appears in the upper left corner.


That should take care of your problem. I'm not exactly sure how you are getting to the path that you refer to, but I believe with the screenshots that I provided, you should be okay. While I use an iPhone 16 Pro Max, the iOS is still 18.6.
