EN ISO 15006:2011 (E) DINEN ISO 15006:2012-043 IntroductionThe driver and the veh
25、icle are an integrated system that includes the environment, the primary vehicle controls, the instrumentation, and the transport information and control systems (TICS). The driving task, and human capabilities and limitations, are other primary factors. TICS are intended to support the drivers prim
26、ary task, and therefore it is expected that the overall workload of the driver will not be negatively influenced, while performance and comfort should be increased.The multitude of information to be displayed to the driver through TICS may create the need to minimize visual load and make more and be
27、tter use of the auditory channel. This International Standard provides ergonomic specifications for the design and installation of auditory displays presenting speech and tonal information while driving. The aim of these specifications is to help designers to provide auditory signals which meet usab
28、ility, comfort and safety criteria.EN ISO 15006:2011 (E) DINEN ISO 15006:2012-0441 ScopeThis International Standard establishes ergonomic specifications for the presentation of auditory information related to transport information and control systems (TICS) through speech or sounds. It applies prima
29、rily to the use of auditory displays to the driver when the vehicle is in motion, but it may also be applied when the vehicle is stationary. It presents a set of requirements and recommendations for in-vehicle auditory signals from TICS, and provides characteristics and functional factors for maximi
30、zing auditory signal intelligibility and utility while helping prevent auditory or mental overload.2 Normative referencesThe following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest
31、 edition of the referenced document (including any amendments) applies.ISO 532, Acoustics Method for calculating loudness level 1)ISO 5128:1980, Acoustics Measurement of noise inside motor vehiclesISO/TS 16951, Road vehicles Ergonomic aspects of transport information and control systems (TICS) Proce

35、 to ISO 532. In practice, references for calculating loudness according to ISO 532 usually implement the code given in DIN 45631 8.EN ISO 15006:2011 (E) DINEN ISO 15006:2012-045 3.5broadband signalcomplex sound whose acoustical energy is distributed over a wide range of frequencies3.6comprehensibili

42、with normal hearing, equal to the loudness of a 1 000 Hz pure tone presented frontally with a sound pressure level of 40 dB, re 20 Pa.NOTE 1 When measured in a free field, this definition for sone is sometimes designated as sone GF. For a diffuse (rather than free) field, the designation is sone GD.
43、 A vehicle interior may be characterized as free field or diffuse field depending on the location (e.g. instrument cluster, audio system speakers, turbulent noise on the windshield) and type of sound (e.g. chime, road noise, and wind noise).NOTE 2 The loudness of a sound that is judged by a listener

48、used to improve the signal location detection and driver attention direction.EXAMPLE A mix of two narrowband signals, with the main audible component centred around 800 Hz, and the other component centred around 3 000 Hz.The urgency of a situation should be reflected by the character of the signal.EN ISO 15006:2011 (E) DINEN ISO 15006:2012-047
