Loudness Growth

An investigation of the relation among individual power-function exponents for 51 adults with normal hearing was undertaken. Three different psychophysical procedures were employed: absolute magnitude estimation (AME), absolute magnitude production (AMP), and cross-modality matching (CMM) between loudness and perceived length. From these procedures, loudness exponents obtained directly from measurements of AME and AMP of loudness were compared to exponents predicted from CMM and AME of perceived length. The means of the distributions of measured and predicted exponents were found to have an identical value of 0.56. Moreover, more than half of the differences between the predicted and measured exponents ranged from -.07 to +.09, giving measured deviations that extend from - 12.5 to 16%. The close agreement between the measured and predicted means, ranges, and distributions of exponent values implies that CMM combined with line-length information can be used with success to determine an individual's rate of loudness growth.

AbstractWe present two absolute magnitude calibrations, MJ and MKs, for red giants with the colour–magnitude diagrams of five Galactic clusters with different metallicities, i.e. M92, M13, M71, M67, and NGC 6791. The combination of the absolute magnitudes of the red giant sequences with the corresponding metallicities provides calibration for absolute magnitude estimation for red giants for a given colour. The calibrations for MJ and MKs are defined in the colour intervals 1.3≤(V−J)0≤2.8 and 1.75≤(V−Ks)0≤3.80 mag, respectively, and they cover the metallicity interval −2.15≤[Fe/H]≤+0.37 dex. The absolute magnitude residuals obtained by the application of the procedure to another set of Galactic clusters lie in the intervals −0.08<ΔMJ≤+0.34 and -0.10< Δ MKs≤ +0.27 mag for MJ and MKs, respectively. The means and standard deviations of the residuals are 〈ΔMJ〉=0.137 and σMJ=0.080, and $〈 Δ MKs〉 =0.109 and σMKs=0.123 mag. The derived relations are applicable to stars older than 4 Gyr, the age of the youngest calibrating cluster.
