A Recommendation that ensures that sound levels between various devices are harmonized in order that listening quality is not degraded was amended at Study Group 12s January meeting.

The amendment takes into account the transmission characteristics for headsets and hands free terminals. The original Recommendation P.313 - provides audio performance requirements for portable digital cordless and mobile handsets, headset and loudspeaker terminals.

Specifications for car mounted hands free terminals will be treated in a new Recommendation in progress and also under study in the Focus Group - From/In/To Cars Communication.
