Conventional noise-excluding techniques are probably inappropriate in ordinary consumer terminals, but it is still possible to limit the adverse effects of ambient noise thr size="2" width="50%" size="2" width="50%"ough careful handset design. In particular it is important that the earpiece is large enough and shaped to cover most of the ear.
