Webthus involve a decrease in the signal-to-noise ratio (SNR) [2–5]. SNR loss is not reﬂected, nor can be predicted, by means of tonal audiometry [6–8]. However, there does appear to be a relationship between the degree of hearing loss and the SNR loss. That is, the greater the degree of hearing loss, the greater the SNR loss [9–11],
