Abstract
A low noise hose including a hollow cylindrical sound absorption member made of soft foam material, a synthetic resin net and/or a spiral wire therein, and a sound insulation tube that is made of soft rubber and has a bellow-like shape disposed about the sound absorption member. The sound insulation tube intercepts the hose internal noise, and it is thicker than a conventional hose so that it is resilient to heat, oil or gas. The sound insulation tube has a bellow-like shape so that it shrinks following the pulsation of intake air, and absorbs it.
