HEAD acoustics International | Noise Suppression Measurement Techniques Part 2 | Voice Quality Online Seminar @HEADacousticsInternational | Uploaded October 2019 | Updated October 2024, 2 hours ago.
This web seminar is part 2 of 2 that covers different noise suppression measurement techniques used in voice quality testing.

As DSP technology has become more cost effective to deploy, it has become possible for communication devices to utilize this power to actively suppress background noise in voice calls. This has improved the quality of voice calls significantly in recent years provided the noise suppression techniques only reduce noise and not affect the voice. Quantifying how much noise suppression has been applied and evaluating its impact on voice quality is important to ensure that the voice call is indeed better with noise suppression, not worse.

This web seminar will cover topics including:
• Evaluating noise suppression using 3QUEST
• What are the differences between ETSI ES 202 396-3 and ETSI TS 103 106
• Background Noise Transmission (BGNT) techniques
