EN 50332-1 – Max. SPL of Portable Audio Devices

EN-50332_1 screenshotThis 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.

ANSI S3.22 and IEC 60318-7 Hearing Aid Test Sequences

The Hearing Aid Standard suite of sequences contains all the major tests from ANSI S3.22 and IEC 60318-7, as well as some of the additional ‘Annex C’ sequences from the 2003 ANSI standard. Each test, as outlined in the standards, is contained in a single test sequence.  These sequences can each be run independently. There are also several full test sequences, which call up the required individual tests to run a complete standard test suite.

Hearing Aid Compatibility to TIA 1083 and FCC Part 68.316

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-470-C Telephone Test Sequences

TIA-470C displayThis test sequence implements all the electroacoustic tests required by TIA-470.110-C, outputting the results as a report or writing to a database. Future releases of this sequence are planned to cover headset and speakerphone testing, and will be developed when the relevant subsections of TIA-470 are approved. The test sequence contains all the major clauses of TIA470C, and also includes calibration sequences and sub-sequences. The test sequences can be used as they are to test to the standard, or modified by the user for custom in-house tests based on the standard.

EN-50332-2: Measuring SPL of Portable Devices

EN50332_screenshotThese two sequences follow the test standard detailed in EN50332-2 for measuring the maximum levels of portable music players and earphones/headphones. This section of the standard covers the individual testing of the devices rather than the combined testing that is detailed in part 1. Note that the physical setup and connections will be different between the two sequences. Please read the hardware and calibration sections of this instruction carefully.
