I have always assumed that they modulate continuously between max and min. Obviously you can only provide the engineering data at a limited number of...

There is a bit more of a quote from the report and its author here The Daily Mail and the Telegraph seem to be responsible for some of the report...
Sorry but that's a bit meaningless as a statement. Too loud in what circumstances? Clearly there are circumstances where they are not too loud eg my...
