The work of preparing International Standa
19、rds is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also tak
20、e part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.The main task of technical committees is t
21、o prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.Attention is drawn to the possibility t

24、nstrumentation, 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 primary task, and therefore it is expected that the overall workload of the driver will not be negat
25、ively 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 better use of the auditory channel. This International Standard provides ergonomic specifications
26、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 usability, comfort and safety criteria.ISO 15006:2011(E) ISO 2011 All rights reserved vBS EN ISO 150

28、information related to transport information and control systems (TICS) through speech or sounds. It applies primarily 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 recomme
29、ndations for in-vehicle auditory signals from TICS, and provides characteristics and functional factors for maximizing auditory signal intelligibility and utility while helping prevent auditory or mental overload.2 Normative referencesThe following referenced documents are indispensable for the appl

49、g listener comfort against signal audibility. The latter is primarily a function of the signal-to-noise ratio (SNR) between the auditory signal and the ambient auditory noise. It should be kept in mind that loudness depends on the level of the ambient auditory noise and on the level of the auditory signal within a given frequency band. Therefore, loudness at a given SNR increases with rising ambient auditory noise.4.2.2 Measuring sound loudnessThe method for measuring and evaluating the loudness of auditory signals shall be as
