Nothing to worry about or to be confused. Your company simply flys according
ICAO PANS OPS Doc 8168 Vol I - Part V - Chap. 3.1.2.1 - Procedure A.
That was tested repeatedly on different airports in Germany back in the 80īs, also the Procedure B was checked. However the differences - max 1 - 3 db perceived noise level - are not considered to be significant enough to recommend only one of the two ICAO procedures, or probably any specific type or company related procedure.
As mutt pointed out earlier very correct, the best method of noise abatement is to get as much distance possible between your aircraft and the recepient on the ground.
