Phase-correct vector summation is essential in cochlear models

Evidence

The vector diagram shows the importance of a vector summation that leads to a very small residual vector, while summing the magnitudes of the vectors of the wavelets and neglecting their phase would lead, incorrectly, to a relatively large magnitude. — Professor Dr.-Ing.
