We're interested in how closely these two scores correlate if >at all. We showed positive correlations at 0.5 and 2.0 kHz but not at 4.0 kHz. See Patterson, R.D., Nimmo-Smith, I., Weber, D.L., and Milroy, R. (1982). The deterioration of hearing with age: Frequency selectivity, the critical ratio, the audiogram, and speech threshold. J. Acoust. Soc. Am., 72, 1788-1803. There is a table of correlations on page 1794. Cheers Roy P __________________________________________________ Roy D.
