Abstract
The Mission Critical Voice quality of experience measurement system is utilized for a variety of measurements for push-to-talk communications systems. Volume, both transmitted and received by a communications device, can impact audio distortion levels within the measurement system. The goal of this project is to develop a measurement that captures audio distortion from overdriving speech into a transmit device and how that comes through the communications system and takes these measurements across a series of volume settings. This presentation focuses on the development of that specific distortion measurement and the methods developed to find optimal transmit volume settings as well as the mathematical analysis completed to accomplish this.Pub Type
