Introduction to RT60 reverberation time measurements with the XL2.
The webinar introduces the standard procedures for measuring the airborne and impact sound insulation, and provides additional information about the required equipment and the related terms and standards.
Testing the quality of loudspeakers or microphones built into smart devices can be tricky, simply because there are no input or output connectors provided. The webinar presents a practical solution to this challenge, by introducing the concept of 'open loop' testing. This approach allows quick measurement of the most relevant acoustic parameters such as frequency response, sensitivity or audible distortions in an industrial environment.
This webinar highlights the challenge of evaluating the Audio quality of the output of devices that have no connected input. The test signal first has to be stored on the Device Under Test (DUT) and then replayed by the DUT during the test measurement. Further, the Audio analyzer must trigger from and synchronize correctly to this incoming asynchronous signal.
