BS 7594:2011 音频感应环路系统(AFILS)的实施规范

This British Standard gives recommendations for and guidance on the design, planning, installation, testing, operation and maintenance of an audio frequency induction loop system (AFILS) intended for communicating speech, music and/or other signals. It is mainly concerned with AFILS for hearing enhancement, in which the signals are communicated to users of hearing aids equipped with magnetic pick-up coils. However, most of the standard also applies to AFILS used for other purposes, and some additional information on these purposes is given in Section 3. This standard does not apply to induction-loop systems which use a carrier frequency, nor to other systems for hearing enhancement purposes which do not use magnetic induction.

BS EN 61883-1:2009 消费性音频/视频设备.数字接口.概述

This part of IEC 61883 specifies a digital interface for consumer electronic audio/video equipment using IEEE 1394. It describes the general packet format, data flow management and connection management for audio-visual data, and also the general transmission rules for control commands. The object of this standard is to define a transmission protocol for audio-visual data and control commands which provides for the interconnection of digital audio and video equipment, using IEEE 1394.

BS EN 62458:2011 音响系统设备.声电变换器.大信号参数的测定

This International Standard applies to transducers such as loudspeaker drive units, loudspeaker systems, headphones, micro-speakers, shakers and other actuators using either an electro-dynamical or electro-magnetic motor coupled with a mechanical suspension. The large signal behaviour of the transducer is modelled by a lumped parameter model considering dominant nonlinearities such as force factor, stiffness and inductance as shown in Figure 1. The standard defines the basic terms and parameters of the model, the methods of measurements and the way the results should be reported.

BS EN 60268-7:2011 声系统设备.头戴受话器及耳机

This part of IEC 60268, is applicable to headphones, headsets, earphones and earsets, intended to be used on, or in, the human ear. It also applies to equipment, such as pre-amplifiers, passive networks and power supplies which form an integral part of the headphone system. It does not deal with: a) safety, for which reference should be made to IEC 60065 or another appropriate standard; b) the characteristics of microphones of headsets, for which reference should be made to IEC 60268-4; c) earphones and other devices for hearing aids, for which reference should be made to IEC 60118-0; d) headphones for audiometry; e) headphones and other devices which form part of an active ear-defender system, although some of its provisions may be applicable. This standard specifies the characteristics which should be included by the manufacturer in specifications, and relevant methods of measurement. It includes a classification of the different types of earphone, mainly characterized by the way in which the transducer is coupled acoustically to the ear, and a classification code which may also be used for marking.

BS EN 62459:2011 音响系统设备.电声换能器.悬挂件的测量

This International Standard applies to the suspension parts of electroacoustic transducers (for example, loudspeakers). It defines the parameters and measurement method to determine the properties of suspension parts like spiders, surrounds, diaphragms or cones before being assembled in the transducer. The measurement results are needed for engineering design purposes and for quality control. Furthermore, this method is intended to improve the correlation of measurements between suspension-part manufacturers and loudspeaker manufacturers. The measurement methods provide parameters based on linear and nonlinear modelling of the suspension part and uses both static and dynamic techniques.
