The webinar explains the basic test setup and strategy for 100V voice alarm systems. Furthermore, it covers the most common terms and parameters such as complex impedance, phase, power factor or the recommended test signal level and frequency.

The Rating Level Lr is used to assess the level of disturbance of industrial or environmental noise. Its evaluation begins with a measurement of the averaged sound pressure level LAeq. Penalties are applied for tonal and impulsive characteristics dependent on the time of the day.

The webinar explains how to objectively identify the relevant impulses and tones using both survey grade and engineering grade methods including FFT tonal assessment by the reference method, and how to calculate the applicable penalties.

The acoustic performance directly affects the speech intelligibility within a classroom, which in turn has a big impact on the learning success of the students.

The webinar therefore explains how to evaluate the acoustic performance, introduces typical target specifications, and introduces potential measures to improve a deficient classroom.

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.

• Testing Smart Devices

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.
