Sound delivery system (10) stimulates the two hemispheres of the brain separately by delivering different vibro-acoustic vibrations to the left and right sides of a person's body. Split resonator (30) includes left resonator member (32L) with attached left transducer (23) and right resonator member (32R) with attached right transducer (24). Left and right resonator members are spaced apart to prevent vibrations being transmitted between resonator members.
