HEAD acoustics International | Noise Simulation Methodologies | Voice Quality Online Seminar @HEADacousticsInternational | Uploaded January 2019 | Updated October 2024, 2 minutes ago.
This web seminar introduces to the common methods for reproducing background noise in a lab and ways to verify the accuracy and repeatability of that noise reproduction.
Modern communication devices can be exposed to a wide variety of background noises that can stress a noise suppression system in many ways. In order to properly test a noise suppression system it is desirable to expose devices to a wide variety of background noises. But in order to ensure that two tests are done comparably, it is important that the background noise is accurate and repeatable. If that device is not exposed to such a background noise, then it is very difficult to quantify the noise suppressor’s performance in a meaningful way.
Topics to be covered include:
• Review of the popular ETSI ES 202 396-1 standard to reproduce background noise using a diffuse sound field approach
• Introduction to the new ETSI TS 103 224 standard for sound field simulation
• Differences between the two ETSI methodologies
• Ways to verify the accuracy and reproducibility of background noise simulations
