Re: Unilateral hearing loss

Shooting for right-handers may increase the magnitude for the ear effect but I believe it is also present when noise exposure is not known to be more pronounced on either side (Chung et al., 1983). It may be worth noting that there are asymmetries in olivocochlear function which others have suggested may relate to protection from noise. However, if I remember correctly these asymmetries were demonstrated in humans using contralateral suppression of TEOAEs which is representative of medial olivocochlear function. However, it seems that the lateral olivocochlear bundle is a better candidate for aiding in protection against noise.

The opposite is the case for (right-handed) pistol 

Is it possible that your colleague sees lots of military 
(and former military) patients?  The military uses mostly 
rifles, not pistols, and most people are right-handed.

Just a thought...

Dear list,

a colleague of mine is very interested in unilateral hearing loss. He's been
working in audiology for over 30 years and claims that in his experience it
is much more common for the left ear to be affected than the right.
Furthermore, if the right ear is affected, and the person is also
right-handed, the problems with processing auditory information are much
larger than in cases of left-sided hearing loss and/or left-handedness.
However, he does not know of any publications on the subject. Is there
anyone on the list who knows?

All the best,
