Since most of us live in situations that are suboptimal for music listening every optimization matters.
I had my HVAC replaced recently and these new R410 units are noisy. In fact even GLM warns me that the microphone is picking up a lot of noise and asks me before it calibrates.
Did some research and found a Brinmar compressor blanket. (Search exactly that on Amazon) about $80. This on its own didn’t make as much difference as I expected.
Also I found EVA sound isolation footers for the outside condenser unit (many brands on Amazon) about $24 for the 6” ones.
I installed them this morning and I can say the noise and vibration coming into the living room is much lower. Not as low I wish it were.
If I had space I would relocate the condenser unit but that is not an option for me. Any more optimization would involve located a professional knowledgeable about this - which I assume would be a challenge.
Even if I precool the house for listening sessions the fridge is still audible.
I’m wondering if anyone has tried acoustic absorption devices behind a fridge or perhaps on the wall between the condenser and my living room.
The noisy spectrum has definitely gone up in frequency. Before it was very bassy noise. Now it’s moved up into the midrange. That noise was probably already there just masked by the low frequency noise that was present before.
I wonder if anything would be effective to cut down the remaining noise.
