In electro-acoustics it is common practice to process an acoustic signal by convolving it with a measured or modelled transfer function.Any transfer function can be decomposed into a linear phase component, minimum phase component and an all-pass component.An investigation was done to determine when the contribution of the all-pass component is perceptible.Through a listening experiment, thresholds of audibility were obtained, which can be used to ascertain whether discarding an all-pass component will be audible.If it is not audible discarding the allpass component can be advantageous in many applications.
