Summary:
|
This Recommendation includes communication requirements for in-car communication (ICC). The aim of this Recommendation is to set a base level of function and quality. This Recommendation is aimed at providing an improved communication between all occupants in a motor vehicle. Furthermore, it will ensure the ICC operates to a quality such that the motor vehicle driver does not feel it necessary to turn their head to amplify their voice when talking to other passengers and thus ICC can aid in preventing driver distraction. ICC will utilize integrated microphones and speakers in the motor vehicle cabin to amplify conversation.
To meet these requirements, the use of audio zones within a motor vehicle cabin for speech communications between audio zones, and tests to ensure good speech intelligibility and quality between those zones are defined. This Recommendation covers requirements and test methods for:
1.system stability
2.speech intelligibility
3.speech quality
4.talker localization accuracy
The use of wearable headphones (audiophones) by driver or passengers is outside the scope of this Recommendation.
