Regular distortion laws from electroacoustics describe hearing’s own nonlinear products

Evidence

These equations hold for regular distortions, which are the usual kind produced in electroacoustic networks. In such equipment, the deviation from exact linearity is not very strong, and the equations given above are mostly fulfilled. Knowledge of these kinds of dependencies is helpful when the nonlinear distortion products produced in our hearing system are discussed. — Professor Dr.-Ing. Hugo Fastl, Professor Dr.-Ing.
