It then calculates the voltage required to produce 1 mW into the rated impedance. A series of post processing steps calculates the attenuation curves, their average values and shows them on the final display.

There are several unique Signal Paths used in 600268-1 sequences which are not a part of the default SoundCheck installation. 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. It is recommended that the sequences be run directly from the IEC folder.

The folder contains dependent files required to run the sequences. We use cookies to make our website easier to use and to better understand your needs. The sequence prompts the operator to enter the rated voltage and rated impedance of the DUT. The Hz recorded time waveforms are processed using heterodyne analysis to derive their fundamental values.

Methods for specifying and measuring general characteristics used for equipment performance Status: All signals are 30s long, dBFS rmsstereo, 16bit and have Hz sample rate. Relink dialog Here is a list 06268-1 sequences and their ieec signal paths unique paths are in bold: Headphones and Earphones is an international standard intended to characterize the performance of headphones and earphones. It can also be used to iev the passive attenuation only of a standard non-ANC headphone.

It then enters a loop which will run 5 times. It can be created by passing pink noise through a special filter network defined in IEC Verfahren zur Festlegung und Messung von allgemeinen Kennwerten fuer die Geraeteleistung. This value is converted to dBV and used to calculate the IM and difference frequency stimulus levels.

A special test signal “Program Simulation Noise”, whose spectral content is representative of music and speech. This is an even-only harmonics companion of standard triangle signal. Please download Chrome or Firefox or view our browser tips.

It consists of two pure tones: Setup System, Hardware and Calibration Before attempting to run any of the sequences, read the following setup instructions. You are ready to start the sequence. Hardware Requirements In order to run the sequences, the following hardware is required: Matthew Miller November 15, – 6: No – I don’t want to receive the latest audio 602668-1 information by email.

Customers who bought this product also bought BS Headphone Voltage Sensitivity Final Display. If more than 4 input channels are available, all input signal paths may be assigned to separate hardware channels. If passive, ied to the headphone amp or separate audio power amplifier You are ready to start the sequence. The data from each loop iteration is displayed as it is acquired.

The standard itself is a lengthy document, 9 60628-1 and 3 Annexes covering 46 printed pages. For the purpose a new audio metric is used. Registration required The content you have requested is available only to registered visitors. Software Requirements SoundCheck
