The sequence prompts the operator to enter the rated voltage and rated impedance of the DUT. Learn more about the cookies we 602681 and how to change your settings.

The sequence first plays a stepped sine through both channels of the DUT and captures the sound radiation from the DUT using 2 reference mics.

You may see results of such measurements in the form of histogram on Portable players page. The user is first prompted to enter the rated voltage.

It can be created by passing pink noise through a special filter network defined in IEC Along with listening tests SoundExpert performs objective measurements of audio devices and technologies.

Methods for specifying and measuring general characteristics used for equipment performance.

Germain – What You Think About Try to mine at least hashes. The sequence then goes through a series of acquisition steps to generate four fundamental curves which are then post-processed to calculate crosstalk. For the purpose a new audio metric is 602268-1.

Amendment 1 – Sound system equipment. Part 1: General

Connect the impedance boxes between the headphone amp out and headphone input. The faster, easier way to work with standards. Accept and continue Learn more about the cookies we use and how to change your settings.

First, a pink noise stimulus is played from the noise speakers and recorded by the unoccluded ears. It can also be used to characterize the passive attenuation only of a standard non-ANC headphone. You may experience issues viewing this site in Internet Explorer 9, 10 or Calibrate the Headphone Amplifier channels per the instructions in the SoundCheck 06268-1.

Five separate sequences are provided, each designed to measure specific characteristics. This website is best viewed with browser version of up to Microsoft Internet Explorer 8 or Firefox 3.

Setup System, Hardware and Calibration Before attempting to run any of the sequences, read the following setup instructions. Audio equipment, Audio systems, Communication equipment, Performance testing, 6068-1 testing, Acoustic measurement, Testing conditions, Accuracy, Marking, Test equipment, Experimental data, Graphic representation, Magnetic field measurement, Frequencies, Signal level, Weighting functions, Errors, Calibration.

This sequence satisfies the requirements of Section 8. A series of post-processing steps follow to apply the weighting and correction curves, calculate the 6068-1 and then the Simulated Program Characteristic Voltage is calculated along with the Hz voltage sensitivity. While test signals can be of any kind the measurement procedure stays the same and waveform degradation is measured with a single parameter – Difference level dB.

It then enters a loop which will run 5 times. Worldwide Standards We can source any standard from anywhere in the world.
