I popped a test cd in last night to hear what was on it.
Found that I can still hear the TV whistle.I'm nearly 67.
Still didn't like it though!Sounded like my tinnitus amplified!

According to this, I should not bother with super-tweeters Or even extended tweeters

According to this, I should not bother with super-tweeters Or even extended tweeters i don't trust frequecy tests ! all that did was confirm that my computer speakers have lousy frequecy response - like from 80hz to 10khz.

Tis true....here's a quick & dirty (non-log) measure I did on my common garden Logitech computer spkrs + sub. Ugly but good for 50-18kHz, apart from a huge upper bass hump/hole, due likely to a desktop over the sub.  Using this more flexible online freq generator: www.szynalski.com/tone-generator/ Although your desktop spkrs may be playing at say 70-80dB, you should be able to hear down to at least 30-40dB, so flat response unnecessary, those nasty wee spkrs should be fine for the hearing test.

(A quick learning curve on Excel graphing.....) My Logitech X-230 response in more usual Log scale. Arguably not quite as ugly  The HF roughness is probably due to desk paraphenalia reflections & wind noise outside! These wee 40mm drivers have pretty good HF extension.

Harmen have a computer program that help you learn how to listen:
How to Listen is a desktop software application developed by the Harman International R&D group for the purpose of training and selecting listeners used in audio product research, development, and testing. The software consists of a number of training exercises where different kinds of timbral, spatial and dynamic distortions commonly found within the recording and audio chains are simulated and added to music.
