<p>The invention relates to a portable device (1) for listening to a musical signal (AS1), that comprises at least one musical signal source (2), at least one external microphone (30a) supplying an external audio signal (AS2), and means (15, 20, 34) for conveying the musical signal and/or the external audio signal to a listening means (22, 23, 24, 25, 40, 41, 42) of said signal, comprising mixing means (34) of the musical signal (AS1) and of the external audio signal. The device further includes means (DSP1, 33, MD1-MD7, SELM) for applying to said external audio signal (AS2) a processing (SPF2) for facilitating the perception of external noises or sounds that can be useful for the security of the user or for communication with someone else while maintaining the auditory comfort, a means for storing a parameter (SETi) defining a mixing ratio (G12/G11) of the musical signal and of the external audio signal, and a forced mixed listening mode in which both the musical signal and the processed external audio signal are unconditionally conveyed to the musical-signal listening means according to the stored mixing ratio.</p> |
