Found the review I was looking for -
http://www.tyrereviews.co.uk/Article/2018-Auto-Express-Summer-Tyre-Test.htm"Auto Express magazine tested ten 225/45 R17 summer tyres,
using a VW Golf at the Continental test facility in Uvalde, Texas."
Michelin PS4 - "Negative:
Noisy, relatively high rolling resistance."
Goodyear Eagle F1 AS3 - "Positive: Well balanced tyre, excellent curved aquaplaning result. Low rolling resistance and
quiet."
This explains why the audi driver I quoted previously, noticed the noise difference between these 2 tyres in particular.
