The tubing assembly has a first end connected to the head assembly and a second end connected to the ear piece assembly. The tubing assembly includes a first acoustic chamber and three insulation chambers. The insulation chambers include a first material having a first density and are disposed around the first acoustic chamber. The tubing assembly also includes an outer layer, which includes a second material having a second density. Moreover, the outer layer is disposed around the insulation chambers. In another embodiment, the outer layer is substantially frictionless and the tubing assembly is flexible. In yet another embodiment, the stethoscope further includes a second acoustic chamber and the insulation chambers are disposed around a portion of the first acoustic chamber and a portion of the second acoustic chamber.
