This specification covers subminiature audio helical retractile cords and straight cords with either stranded wire or tinsel wire conductors, for accessories associated in for the use with microphone,telephone, switchboard, and associated communication equipment. These cords are intended for operations at audio frequencies and temperatures from -55 °C to +85 °C with a high degree of flexibility. Each retractile cord is designed for extension in normal service up to 6 times its nominal retracted helical length.

This technical report applies to loudspeakers conforming to IEC 61305-5 and intended for home use. The purpose of this report is, in addition to objective testing according to IEC 60268-5, to establich standards for comparison of the sound characteristics of various loudspeakers with each other.Two test procedures are described:- single stimulus ratings- paired comparisons.The procedures described in this report are apllicable to any number of channels.

This part of IEC 60268 specifies methods of measurement for the electrical impedance, sensitivity, directional response pattern, dynamic range and external influences of sound system microphones, and also gives recommendations as to characteristics to be specified. It applies to sound system microphones for all applications for speech and music. It does not apply to measurement microphones, but it does apply to each audio channel of microphones having more than one channel, for example for stereo or similar use. It is also applicable to flush-mounted microphones and to the analogue characteristics of microphones with digital audio output. For the purposes of this International Standard, a microphone includes all such devices as transformers, pre-amplifiers, or other elements that form an integral part of the microphone, up to the output terminals specified by the manufacturer. NOTE The characteristics specified in this standard do not completely describe the subjective response of the microphone. Further work is necessary to find new definitions and measurement procedures for a later replacement by objective characteristics of at least some of the subjective descriptions use to describe microphone performance.

This Part 2 of EN 50332 specifies matching values for the use of battery-operated audio equipment and headphones/earphones defined for the use with those and with standardised connectors allowing to combine components of different manufacturers or different design sold separately in order to avoid possible hearing impairment by excessive sound pressure resulting from them. Compared with "one-package sets" the sound pressure level at the ear cannot be fixed by only one condition but needs at least two characteristics, one each for player and the headphones/earphones, defined by the matching values for their connection.

This specification covers headsets and headset-microphone assemblies intended for use in medium ambient noise level environments of 85-105 dBA SPL (Sound Pressure Level). These headset-microphone assemblies use dynamic earphones of the moving coil type that transform electrical energy into acoustical energy. A complete assembly includes headband, earphone(s) mounted in rigid earcups, with cord assemblies to meet requirements of various military service activities. The assemblies include, as required, a noise canceling microphone and boom.
