Actually that shouldn't be necessary. Try with
(defun beep-when-frame-size-changed (frame)
(when (or (/= (window-pixel-width-before-size-change (frame-root-window frame))
(window-pixel-width (frame-root-window frame)))
(/= (window-pixel-height-before-size-change (frame-root-window frame))
(window-pixel-height (frame-root-window frame))))
(ding)))
(add-hook 'window-size-change-functions 'beep-when-frame-size-changed)
