Technologies are generally described for hybrid acoustic damping materials that may be used in noise, vibration, and harshness mitigation. In some examples, solvated acrylic, silicone, and/or urethane materials may be blended in selected proportions to form a hybrid acoustic damping material. Characteristics of the components of the hybrid acoustic damping material such as viscosity and proportions may be selected for a desired composite loss factor vs. temperature characteristic of the material. In some examples, a broad temperature range of damping or a targeted temperature region may be achieved based on the composition of the hybrid acoustic damping material. To achieve a uniform stable blend with a consistent viscosity, individual component materials may be selected with similar molecular weight/viscosity. Compatible solvents may be added during blending of the components. In various example applications, the hybrid acoustic damping material may be used in vehicle brake applications to reduce brake noise/vibration.
