The browser client supports a variety of audio alerts. Since each alert can be configured to use its own wav file, disabling a specific alert on the server (i.e. for all users) is as simple as configuring a specific alert to use a wav file that makes no sound.
While we will likely have more fine-grained user configuration for which alerts to play over time, I think it would be useful to include a 'nosound.wav' file in the repository so admins have the option of squashing specific types of alerts for all users on the server. It's also useful for development where you may want to disable certain repetitive sounds, but not all sounds.
For example, to use nosound.wav to silence the patron search success alert:
mkdir -p /openils/var/web/audio/notifications/success/patron/
cd /openils/var/web/audio/notifications/success/patron/
ln -s ../../nosound.wav by_search.wav # or just copy it
Patch en route.
nosound.wav file created and pushed:

File was created (by me) via 'arecord < /dev/zero > nosound.wav' with a sub-second duration.
As noted in the commit:
To test:
[1] mkdir -p /openils/
[2] cd /openils/
[3] ln -s ../../nosound.wav by_search.wav
[4] Perform a patron search in the browser client and confirm no sound is played upon successful search.
If patron searches have recently been performed, step 4 may require a cache clear, a different tab, browser restart, eye of newt.
Once confirmed, remove the symlink to recover the original alert sound.
