A telecommunications terminal (100) includes an input audio transducer (111), a receiver (101) for receiving an electrical signal representing a transmitted audio signal, a noise energy estimator (117) for estimating an audio noise energy input received by the input audio transducer and an audio enhancement means (108) for applying to the received electrical signal in a selected audio frequency band a gain which is greater than the gain applied to audio frequencies of the received electrical signal outside the selected band, the gain applied being a function of the audio noise energy input.
