Hello Jon,

I think you should make speech audiometry in 
noise: BILD (Binaural intelligebility level difference)
or a tone test in noise: BMLD (binaural masking level difference)
to measure your ability to suppress noise. 
Suppressing noise is one important effect of normal binaural hearing.
(an other important effect is localisation)
With this tests you get information how your both ears
work together.
