Non-elastic audiofrequency vibrational modes in aluminum and other metals are suggested as a possible reason for the differences reported by various observers using large aluminum alloy bars (or disks) as gravity-wave detectors. Loading of suspended gravity-wave detector bars resulting from the gravitational attraction of the earth is also sufficient to produce the small stresses required for the self-generation of audiofrequency sounds (acoustic emission) in materials. Both the non-elastic mode response and acoustic emission frequencies depend critically on the exact microstructure and/or residual stress state of a bar.
