The scope of this standard is to set up a suitable measuring methodology allowing accurate measurement of the maximum sound pressure level produced by consumer's headphones and earphones when associated with portable audio equipment. NOTE This standard does not apply to acoustically open or acoustically closed headphones associated with mains operated Hi-Fi home equipement nor does it apply to headphones for medical purposes (hard of hearing, etc.) or to headphones or similar parts being part of active hearing protection systems. Wireless headphones are neither included, conditions for them may be derived accordingly. Other requirements for safety, e.g. for noise protection in offices and industry are not affected by this standard. Requested features: - The method should be reproducible and easily applicable to every type and shape of headphone or earphone available on the market (good mechanical adaptability). - As safety and health are addressed, the method should faithfully reflect the pressure level effective at the user's hearing (good correlation with subjective tests). - And finally, it is desirable to establish a global measuring procedure, including each component in the chain: Portable set + specific test signal + associated headphone or earphone. The standard is split into two parts: - Part 1 deals with sets provided as a package equipment by the manufacturer. In this case, "Portable audio equipment" means the association of one set (compact cassette player, CD player, FM radio receiver, with its headphone or earphone. - Part 2 (under consideration at present time) gives guidelines to associate portable audio sets (compact cassette player, CD player, FM radio receiver, ...) with headphones or earphones coming from a different manufacturer.

This Technical Report specifies a physical test method for level-dependent sound-restoration ear-muffs. The physical measurements are made with the acoustic test fixture (ATF) according to ISO/TR 4869-3 or with a suitable head and torso simulator (HATS) with a suitable acoustic isolation (see clause 7). The results of these tests in combination with the results from the ISO 4869-1 tests can be used to estimate the effective A-weighted sound pressure level when sound restoration ear-muffs are worn. The method described is not suitable for measurement of the effective sound pressure level under ear-muffs in the case of impulsive noise nor for active noise reduction ear-muffs.

1.1 This guide defines simple economical procedures for testing or comparing the performance of acoustic emission sensors. These procedures allow the user to check for degradation of a sensor or to select sets of sensors with nearly identical performances. The procedures are not capable of providing an absolute calibration of the sensor nor do they assure transferability of data sets between organizations. 1.2 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

The document describes an acoustic coupler for loading supra-aural audiometric earphones as specified in ISO 389-1 with a specified acoustic impedance, when calibrating audiometers, in the frequency range of 125 Hz to 8.000 Hz. The sound pressure developed by an earphone is not, in general, the same in the coupler as in person's ear. However, the IEC recommends its use as a simple and ready means for the exchange of specifications on audiometers and for the calibration of specified earphones used in audiometry.#,,#
