Connect the impedance boxes between the headphone amp out and headphone input.
Headphones and earphones Status: The play and record acquisition takes place 3 times and the user is prompted to reposition the DUT on the HATS in between acquisitions. You may find similar items within these categories by selecting from the choices below:. The sequence then goes through a series of acquisition steps to generate four fundamental curves which are then post-processed to calculate crosstalk. Sound System Equipment — Part 7: Worldwide Standards We can source any standard from anywhere in the world.
IEC Headphone Test Sequences – Listen, Inc.
It is recommended that the sequences be run directly from the IEC folder. Your basket is empty. A statistics step calculates the mean of the 3 unoccluded measurements.
The sequence first plays a stepped sine through 6268 channels of the DUT and captures the sound radiation from the DUT using 2 reference mics.
Crosstalk and radiation curves are then shown on the final display. Take the smart route to manage 60628 device compliance. First, a pink noise stimulus is played from the noise speakers and recorded by the unoccluded ears. The data from each loop iteration is displayed as it is acquired.

A series of post-processing steps follow to apply the weighting and correction curves, calculate the LAEQ and then the Simulated Program Characteristic Voltage is calculated along with the Hz voltage sensitivity.
Click to learn more. Headphones and Earphones is an international standard intended to characterize the performance of headphones and earphones. A series of post processing steps calculates the attenuation curves, their average values and shows them on the final display.
Software Requirements SoundCheck If more than 4 input channels are available, all input signal paths may be assigned to separate hardware channels.
Relink dialog Here is a list of sequences and their default signal paths unique paths are in bold: This value is converted to dBV and used to calculate the IM and difference frequency stimulus levels.
