This is the confirmation of my youngest son's hearing test. As you can see that a result of 20db or less satisfactory, but due to the level of loss, he does not have mild, but rather moderate hearing loss.

This means we don't have to have hearing aids, but if the loss got greater he would not be able hear speech. At the moment, he will struggle to hear "f", "s" and "th" sounds, so in my opinion, we had no choice but to get him hearing aids.
