I wouldn’t say that the test was not thorough. I would prefer to see an MCL score, but that is just my preference. I would like to see a plain word recognition as well as the one that is in noise.
Bottom line: Do I think you should get hearing aids? Yes, I do. Understand that not much with our bodies gets better with age (believe me on that one!) Unless there is some other underlying factor with your ears, it’s a safe bet that your hearing is not going to get better on its own. Also, word recognition is a measure of how well your ears and your brain are working together to comprehend words. You’re right on the border between “Good” and “Not so good.” Only very rarely have I seen WR get better. Even with top of the line hearing aids, you can expect to maybe get 85% of the words correct. Now, with context, verbal cues, body language, etc., that are found in normal conversation, you will probably understand closer to 90%-95% on average. This is pretty good.
So, yes, without knowing anything else, I would say go ahead and get the hearing aids. Keep the brain active and understanding.
