Alcohol is a general anesthetic. That means that bodily responses to stimulus are attenuated.http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2031886/

"Our results showed that there was a positive association between increasing breath alcohol concentration and the magnitude of the increase in hearing threshold for most hearing frequencies. This was calculated by using the Pearson Regression Coefficient Ratio which was up to 0.6 for hearing at 1000 Hz. Over 90% of subjects had raised auditory thresholds in three or more frequencies; this was more marked in the lower frequencies"
"...increase in hearing threshold" means that the ears became less sensitive.
It appears that bass frequencies are affected more.
