A method of measuring the degradation of a data stream owing to the influence of errors thereon is disclosed.

A particular application of the method to the selection of one of a number of possible speech coding methods for use in transmitting speech across a radio link ( ) from a mobile phone ( ) to a base station ( ) is described.
