You can also put rubber grommets around the device’s motor or buy a new air compressor altogether. How do you make an air compressor quieter? By wrapping the motor, covering the intake with a muffler, encapsulating/blocking off the compressor, or moving the intake, you should have a less noisy air compressor. These range in size from tiny pancake compressors to huge units that are going to be appropriately noisy. If you own or rent home improvement devices like grinders, sanders, jackhammers, nail guns, and spray painters, then you’re using some form of air compressor.
