In the most recent posting on its Radio Insights blog, HARKER RESEARCH asks, "Is NIELSEN's PPM making radio unlistenable?"
HARKER notes, "Recently NIELSEN touted ratings growth coinciding with the roll-out of enhanced PPM encoding (eCBET). According to NIELSEN, the enhanced encoding, 'Makes the PPM codes stronger and more robust, which improves code detection in challenging acoustic environments.'

The sound of the tell-tale buzz-saw sound of encoding is now a regular feature of some encoded radio stations."
