Not really all of them. Here's what the distributions do:

Prelude and Spacemacs:

  (setq ring-bell-function 'ignore)

better-defaults:

  (setq visible-bell t)

Doom:

  (setq ring-bell-function #'doom-themes-visual-bell-fn
        visible-bell t)

  (defface doom-visual-bell '((t (:inherit error)))
    "Face to use for the mode-line when `doom-themes-visual-bell-config'
  is used."
    :group 'doom-themes)

  ;;;###autoload
  (defun doom-themes-visual-bell-fn ()
    "Blink the mode-line red briefly. Set `ring-bell-function' to this
  to use it."
    (let ((doom-themes--bell-cookie (face-remap-add-relative 'mode-line 
'doom-visual-bell)))
      (force-mode-line-update)
      (run-with-timer 0.15 nil
                      (lambda (cookie buf)
                        (with-current-buffer buf
                          (face-remap-remove-relative cookie)
                          (force-mode-line-update)))
                      doom-themes--bell-cookie
                      (current-buffer))))
