The hearing aid ratings (M and T ratings; HAC) all are determined by measuring the cell phone RF emissions.
Well, there are a lot of audio characteristics that the hearing aid ratings do not cover. It would be difficult to have more characteristics mandated for the HAC rating because the other characteristics do not directly affect the hearing aid performance.
Here is a website I was very happy to find: http://www.arcx.com/sites/AudioQuality.htm
It is the first website I have seen that breaks down different audio characteristics.
I encourage everyone to read it. It does mention the fact that RF measurement for cell phones is only part of the audio quality measurement.
However, as much as I would love to see an "Overall Audio Quality" measurement that is broken down by different characteristics, I don't see it happening since these factors do not directly affect the hearing aid the way that RF interference does (humming, etc. noise).
