Anyone use a sound blanket to reduce A/C noise?

[callbay]

I have a relatively loud heat pump near our back deck and I would like to reduce the noise from the unit.

Anyone had good results using a sound blanket on the outside unit compressor like this one?

Just wanted some BITOG reviews.

I use ear plugs instead.

Haven't used it myself. However, as someone who has dealt with many acoustical and noise issues, the principle is sound. Sound deadening blankets are used in all sorts of industrial applications and are quite effective. Be sure to close-up/tape off all gaps as even the smallest matter.

I bought 2 trane heat pumps over the recent years and asked for compressor blankets on both.

Another help to reduce noise is to make sure all the cabinet screws are tight.

I replace my screws with longer ones and added rubber grommets. Cut the vibration noise by about 75%. The grommets were rubber faucet washers. Cost: $4 for screws and grommets.

My neighbor didn't have it, their central A/C is outside my bedroom and they run it almost all day and night. I'm not very happy at all

My central A/C has it and it seems to run quieter than my neighbors' A/C. But my A/C didn't run for a while now, the last time it ran was September last year.

You can also damp the sheet-metal cabinet vibration using a constrained-layer dampening tape, like those made by 3M. Another alternative is using sticky-back bitumen pads used to dampen auto-bodies. In a pinch, you can also use the sticky-back waterproofing membrane used by roofers in the valleys.
