WebApr 11, 2024 · The ability to localise a sound in a vertical plane is often attributed to the analysis of the spectral composition of the sound at each ear. In fact, the sound waves arriving at the ears are rebounded from structures such as the shoulders or pinnae, and these rebounds interfere with the sound as it enters the ear canal. WebAug 23, 2016 · It has been suggested (e.g. Hirsh, 1950) that there is a direct connection between the ability to localize sounds and the ability to hear speech in noise. The basis of this argument is that interaural phase differences are cues for both localization and release from masking (i.e. masking level differences). how many of the bolsheviks were jewish
