How do I turn off key tones on Sony Bravia KD43XF7596?

[PhilT59]

I have just bought a new Sony Bravia KD43XF7596 but am unable to turn off the key tones that can be heard when changing channels as there is no option to do this. I have seen some other people have had the same problem with other TVs. Can anyone help as it is driving me mad!!!
