Hey folks,

My father is 65 years old and lives next to my apartment. He didn't haven't had any severe health problems till now. Yesterday I was calling out for him several times at the top of my pitch. But he didn't respond! When I enquired in person, he said he had difficulty hearing lately, like doorbells and alarms. 

 So, I'm considering doing an online hearing test to know if he needs help; that way, it would save me some time too. 

But I have not done this before, and I would like to hear personal experiences of an online hearing test. How safe and accurate is this test?

Any help would be appreciated. Thanks!
