Abstract
A door latch assembly is provided with enhanced acoustic dampening characteristics, and includes a door bolt assembly having an inside barrel and an outside barrel configured for accommodating reciprocal sliding action of the inside barrel between a latch position and a release position. At least one barrel acoustic isolator is associated with at least one of the inside barrel and the outside barrel, and is configured for dampening sound generated by the reciprocal action.
