Moving beyond traditional measurements

Certain audio measurements (e.g., level, frequency response, THD, signal-to-noise ratio, etc.) have been around for a long time, they are very established, well understood, and have served a very, very useful purpose.

Many of these metrics were conceived around the concept of linear time-invariant systems. For the purpose of this discussion, we will refer to these metrics as "traditional engineering metrics".

We find that there are audible artefacts that don't show up appropriately in "traditional engineering metrics" -- as an example, a clearly audible rub and buzz in a speaker may measure very low on THD ... on the other hand, we may find a speaker that exhibits no audible distortion measuring high on THD -- this clearly demonstrates limitations of "traditional engineering metrics" in terms of correlating the objective metric to the subjective perception.

Measurements are, thus, evolving to accommodate psychoacoustic phenomena such as masking, etc.

The panel of experts are well-respected leaders in their field (this will NOT be a sales pitch). They will share their views on how this field is evolving and the direction we are heading towards.

The panel will solicit input from the audience -- since engineers are now designing products that are inherently designed to be non-linear and time-varying -- a departure from the tenets underlying the "traditional engineering metrics".
