Abstract (en)

[origin: WO0203664A1] A telephone is disclosed, comprising a capacitive sensor for monitoring the environment of the loudspeaker. It is thus avoided that a telephone in hands-free mode produces an unacceptably high sound level when the telephone is held with the loudspeaker to the ear of the user.
