Bridging Audiology and Psychology

%5,'*,1* $8',2/2*<$1' 36<&+2/2*< We see an ascending curve between 500 and 2,000 Hz, which corresponds to an approximate slope of between 6 and 18 dB per octave, then a dome between 2,000 and 4,000 Hz, and then a slight descent. We find this curve in your book "L’oreille et le langage" (The Ear and Language) when you talk about the musical ear. Perhaps you could explain to us what this curve corresponds to on the physiological level? $W WKH OHYHO RI SXUH SK\VLFV LW LQGLFDWHV WKH UHVSRQVHV RI WKH HDU ZKHQ LW IXQFWLRQV ZHOO ,W DFWXDOO\ FRUUHVSRQGV WR :HJHO¶V ³OHPRQ VKDSHG FXUYH´ EXW LQYHUWHG ,QGHHG :HJHO¶V FXUYH LV WKH UHVSRQVH FXUYH REWDLQHG ZKHQ WKH IUHTXHQFLHV DUH SODFHG RQ WKH DEVFLVVDV D[LV DQG WKH LQWHQVLWLHV RQ WKH DVFHQGLQJ RUGLQDWHV $Q LQLWLDO WKUHVKROG LV REWDLQHG LQ WKH ORZHU SDUW VWDUWLQJ IURP D PLQLPXP WKDW EHJLQV LQ WKH ORZ IUHTXHQFLHV DURXQG ± G% WKHQ DSSURDFKHV WKH FXUYH RI WKH DEVFLVVDV EHWZHHQ DQG +] DQG ULVHV DJDLQ WR ± G% LQ WKH WUHEOHV EHWZHHQ DQG +] 7KLV FXUYH LV FRPSOHWHG DQG DGRSWV WKH VKDSH RI D OHPRQ ZKHQ VRXQGV RI LQFUHDVLQJ LQWHQVLW\ DUH VHQW REWDLQLQJ D FXUYH RI PD[LPXP WKUHVKROGV WKDW GHWHUPLQH WKH SRLQW ZKHUH WKH HDU EHJLQV WR VXIIHU WKH SDLQ WKUHVKROGV 7KHVH WKUHVKROGV DOVR VWDUW LQ WKH EDVV UDQJH DW ± G% UHWXUQLQJ WR WKH ILUVW FXUYH WKHQ UHDFK ± G% EHWZHHQ DQG +] RQO\ WR IDOO LQ WKH WUHEOHV DQG UHMRLQ WKH ILUVW FXUYH You can nd this book on Amazon
