Using Listening Effort to Measure Audio Quality
Instead, our friends in Berkeley have redefined the problem in terms of listening effort. How *hard* is it to understand the audio, especially as we go about our business? Do you enjoy listening to the audio? Do you have to concentrate on the audio to understand it? How much work does it take to understand the audio signal in noisy and multi-speaker situations?
We will review the literature on listening effort, which started with the seminal paper by Sarampalis, Kalluri, Edwards and Hafter. What does listening effort mean? How is it measured? Why is this important? This is not the audio measure to use for perfect audio. We want to better understand how audio is heard in difficult situations, when the environment is loud, the device is less than perfect, or when the listener has auditory problems.
