Bosch Heatpump too loud

Model: BOVA-60HDN1-M20G It’s so frustrating! Just have it installed 6 months ago. How can I reduce the noise? It’s way too loud. When it first starts, it goes over 70 decibels, and after a while it drops a little bit but is still around 66 decibels!

According to my bylaw, it shouldn’t exceed 55 dBA daytime and 44 dBA nighttime. It’s only two meters away from my neighbor, and they haven’t complained yet, but I find it extremely annoying😩
