Abstract

An improved acoustic isolation apparatus for reducing the total acoustic noise of a disc drive assembly and the like, comprising at least one acoustic compliance area disposed between an excitation source and a support member to impede coupling of vibrations from the excitation source to the support member to prevent the vibrations from inducing harmonic vibrations in the support member, thus reducing the total acoustic noise.
