12. A method comprising:
determining if there is a touch at a tactile audio display comprising actuators configured to produce tactile feedback via touch at the tactile audio display in dependence on an input tactile feedback signal and to produce an acoustic audio signal from the tactile audio display in dependence on an input audio signal;
if there is a determined touch, performing a first differential signal processing on the input tactile feedback signal and the input audio signal, before provision to the actuators of the tactile audio display, to cause a relative attenuation between a lower frequency range and a higher frequency range for the input audio signal compared to the input tactile feedback signal;
determining at least a location on the tactile audio display that has been touched and causing a relative attenuation between a lower frequency range and a higher frequency range for the input audio signal compared to the input tactile feedback signal selectively for a first set of one or more actuators adjacent the determined location; and
applying attenuation at lower-frequencies to the input audio signal for the first set of one or more actuators adjacent the determined location and configured to apply amplification at lower-frequencies to the input audio signal for a second set the one or more actuators not adjacent the determined location.
