I must start by saying that I like the sound of smoothrunning sewing machines. The sound you hear from a running sewing machine canbe changed in many ways. Mechanical machines must be properly lubricated tosound properly. Sewing machines sound and run better sitting on a pad and notsitting directly on a desk or table setting up a vibration. Try using a foldedhand towel, heavy place mat or pad made from batting scraps. Pads can also bepurchased, like the one sold by Martelli. Martelli has a sales video thatexplains what a pad for a sewing machine does. Some machines have a sound that irritatesmany people and cannot be changed easily.
