IEC-60268-7 Headphone Sequences/在： Free Headphone & Headset Sequences /通过： Zarina
IEC-60268-7: Sound System Equipment – Part 7: Headphones and Earphones is an international standard intended to characterize the performance of headphones and earphones. The standard itself is a lengthy document, 9 Sections and 3 Annexes covering 46 printed pages. These SoundCheck sequences focus on the electro-acoustic tests which are detailed in Section 8 “Characteristics to be specified and their method of measurement”.
Five separate sequences are provided, each designed to measure specific characteristics. This approach provides the user with the flexibility to measure all or some of the characteristics of their headphone.
Triggered Record Using WAV File (Version 16.0 and earlier)/在： Free Audio Electronic Sequences, Free Loudspeaker Sequences /通过： Zarina
This sequence allows you to test devices without an analog input such as tablets, cellphones and MP3 players. A stimulus WAV file is created in SoundCheck, and copied to the device under test, where it is played and the response recorded in SoundCheck as if the stimulus were played directly from SoundCheck. The stimulus WAV file to be used on the device under test (DUT) may be customized in the stimulus step.
Note that this sequence uses the level-based trigger available in SoundCheck 16.0 and earlier. If you are using version 16.1 or later, please see the frequency-trigger based sequence which takes advantage of new functionality to offer more robust triggering.
EN 50332-1 – Max. SPL of Portable Audio Devices/在： For Purchase Audio Electronic Sequences /通过： Zarina
This sequence follows the test standard detailed in EN50332-1 (2013) for measuring the maximum sound pressure for portable music players and the earphones/headphones they are bundled with. The test involves loading a weighted pink noise stimulus file (as specified by IEC 268) onto the portable device and playing it through the earphones at the player’s maximum volume.
AGC Hearing Aid – Reference Gain & EIN Test Sequence/在： Free Hearing Aid Sequences /通过： Zarina
This sequence performs two of the measurements from the ANSI hearing aid test standard S3.22-1996. The first part, in accordance with section 6.7 of the standard, helps the user set the reference test gain for the hearing aid, which is used for multiple measurements in the standard. The second part, from section 6.12, tests the equivalent input noise (EIN) of the device.
ANSI S3.22 Hearing Aid Test Sequences/在： For Purchase Hearing Aid Sequences /通过： Zarina
These sequences include all the tests from ANSI S3.22:2014 as well as some of the additional ‘Annex C’ tests from the 2014 ANSI standard. This guide describes the basic functionality of each sequence and details the process of hardware setup and calibration.
Each test, as outlined in the standards, is contained in a single test sequence and can be run independently. The ‘— HA ANSI S3.22_2014 Product Test — master sequence’, calls all the required individual test sequences to run a complete standard test suite. It also creates or recalls a limits file according to the definitions in ANSI S3.22:2014 and assists in setting the correct Reference Test Setting for the device being tested. The name of the master sequence is bracketed by dashes to separate it from the individual test sequences.
Hearing Aid Compatibility to TIA 1083 and FCC Part 68.316/在： For Purchase Telephone Sequences /通过： Zarina
These two test sequences are designed to test the hearing aid compatibility of a telephone according to the TIA 1083 and FCC Part 68.316 standards. These sequences, which rely on the user having radial and axial HAC probes, play the appropriate test signals, measure the response and compare them to the limits in the standard. These pre-written sequences enable the user to immediately test to the relevant standards, and can be fully modified to meet any custom testing needs if desired.
TIA-920-A Sequence for Wideband Digital Phones/在： For Purchase Telephone Sequences /通过： Zarina
This sequence has been superseded by TIA 920-B test sequence.
TIA-810-B Standard for Narrowband Digital Phones/在： For Purchase Telephone Sequences /通过： Zarina
This sequence has been superseded by the TIA 920-B test sequence.
