hearing test apps?

Greetings to all. To start off this post, let me give you some background. I first started experiencing hearing loss after I attended a wedding back in June. Since then, my hearing has never been the same, even though a visit with a local audiologist said that my hearing test was normal. More recently, however, I've noticed an even bigger drop in my ability to hear, especially in loud or very crowded places, to the point where loud noises bother my ears. Are there any apps that work with voiceover that will allow me to test my hearing at home while I try to get into a local hearing clinic to have a professional hearing test performed? The apps can be free or paid, it doesn't matter. Thanks in advance.
