Audio (size) discrimination

Bear with me on this as its a bit hard to explain.
With a P.I. the smaller/weaker signal is often the good one and loud 'good' response is iron or other rubbish. We attempt to discriminate by the width of the audio response not the volume as most rings/coins are small.
My point is if you could switch in a revised 'signal booster' with a tight window so that all targets were booster or reduced in volume so that the audio was the same this would reduce the distraction of volume and allow full attention to be paid to the width of the target.
The old problem of a small coin at one inch sounding the same as a coke can at two feet remains but would taking the audio 'blast' out help with identifying the rubbish...it would certainly make it a little easier on the ears.
Shoot me down in flames please. My only excuse is to many hours trudging the wet sand.
 
Hi Brian,
It would be worth trying this on a PI treasure detector. You could have a comparator at the end of the receiver, which switches at a preset signal level. This could activate an audio circuit which gives a constant tone, constant volume. This would then give a good idea of the width of the signal.
I have a PI frisker which does exactly this, in fact the comparator switches a piezo sounder that has a built in oscillator.
Been out with the Goldquest any more?

Having nearly lost the roof we then went into the none stop rain mode so I can't get any photos taken (people don't seem to want to risk digital cameras!)
Goldquest so far is fantastically sensitive so I have been mopping up fine silver rings and engagement rings that others have missed.Burst my eardrums on the first large target then remembered you said to use phones with volume controls.
The sensitivity and SAT made it replace the Deepstar in my affections until I tried my revamped Deepstar and that was a real eye opener. Improved audio discrim. with the use of the SAT and a gain in both depth and sensitivity.
Roy with his two year old Deepstar (no SAT or 10 hour power option) returns this weekend so I should be able to see how they compare.
 
My TV could use this. With all the cable channels, it's a pain always adjusting the volume. <IMG SRC="/forums/images/smile.gif" BORDER=0 ALT=":)">
