EN-50332-2: Measuring SPL of Portable Devices
These 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.

AGC Hearing Aid – Reference Gain & EIN Test Sequence
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
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.

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