Disable Error beep

The sound is comming from the Mac itself without taking the way through the speakers?! That's purely magic. How do you think that the Mac creates the sound?
Although you could disable the error beep of the operating system, another simple solution would be to avoid errors. ;-)

Erik, use
beep off
to disable the error beep.

I've never seen a computer, which uses the internal speaker, if external speakers are connected. It is not getting clear to me, why beeps from the internal speaker are more annoying.
However, your suggestion of "beep off" hits the point.

Lieber Jan,
On the Mac it is possible to have multiple audio channels and direct
them to different devices such as the internal speakers or the Line Out
jack. I have mine set up so that routine computer beeps (mail
notifications, errors, etc.) are directed to the internal speakers and
sounds for which I desire higher fidelity (music, etc.) are directed to
the line out jack which is connected to my stereo. That way if I'm
listening to music (especially if the volume is high) I don't get
interrupted by a loud ping if I happen to get mail.

I've worked on 7 Macs in the past, but the older ones run MacOS 6, 7 and 8, MacOS9 ran on a Umax-Pulsar clone (simple audio interface) and the newer ones with MacOS X were laptops, which have never been connected to external speakers. So this marvelous feature (which is surely a standard feature on high-tech PC-audio today also) was concealed to my curious eyes.
Thanks Doug! I'll buy a Mac as soon as possible -- buying a new Matlab license will be the bigger financial part. But after reading so many postings about problems with Mac/Java/Matlab, I should think of running Matlab in a virtual PC.
So beside "beep off" (and avoiding errors), the OP can reduce the level of the internal speakers also or redirect the warnings to the external speakers.
Kind regards, Jan

Not so much any spelling errors as the .de at the end of your email
address!

What can be done certainly depends on what software you have installed.
I use a utility called SoundSource,
<http://rogueamoeba.com/freebies/>
that allows me to direct so-called "Output" to one channel and the
"System" sounds to another. I happen to have three channels: the
internal speakers, the line out jack and a USB sound device. This
utility only lets you control Output and System sounds, but I believe
there are other utilities (perhaps not free) that allow controlling the
sound on an application basis.
I am still using OS X 10.5.8 (not the latest Snow Leopard) and MATLAB
2009a and, interestingly, the MATLAB error beep is considered an
"Output" and not a "System" sound and is directed to my stereo. I would
guess that the sound comes from the Java side of MATLAB as it sounds
different from the error beep produced by the Terminal application
(which is a System sound). I don't know what software Erik is using
such that his MATLAB error beep comes from the built-in speakers.
I'm sure many of these features are available in Windows, though you
might need additional sound cards or USB devices -- I have little
experience with PC sound.

I'm not sure if I could in any way misunderstand your unambiguous post but for some reason entering "beep off" in the command window doesn't disable the error alert I get from, say, pressing backspace one too many times in command window or entering right parenthesis before the left one in the script editor. What was I supposed to do with "beep off"?
Huge thanks for any help, the alert is driving me nuts!

I had the same annoying problem. It even does it when you are just scrolling through recently-used commands and reach the end. 'beep off' at the Matlab command line was supposed to fix it, I thought, but it didn't. I shut it off through the system audio preferences. It's different on a mac, but still basically the same idea: http://support.apple.com/kb/ht2490

Hi Sauli,
this has been driving me crazy too, but I just figured it out. "beep off" only works for syntax errors. However, the system will still make a "ding" noise if you type a mismatched parenthesis, for example.
Go to Matlab/Preferences/Keyboard/Delimiter Matching and under "Show mismatch with" select "strikethrough", then hit apply. This will get rid of the "ding", in addition to the beep. Note this is for R2007a on Mac, it might be different now.
Enjoy the peace and quiet!

With R2010a pn PC it seems to matter to restart Matlab after entering "beep off". I've now been able to enjoy my work more, hmm.. comprehensively.

This is weird behavior, because R2011a on the Mac (despite many other problems I won't get into here) saves the "beep off" command between sessions. So I typed the command the day I upgraded, and haven't had to since.
So, could somebody please tell me how to permanently turn the beeping off in Windows? Thanks!

Whether that's a bug or not I don't have a clue but...
Put any customization(s) desired in your startup.m file

Ok I just found another annoyance in R2011a for Windows 7, which I don't remember from older versions. Even after doing "beep off" and setting the "indicate mismatch with strikethrough" preference, Matlab STILL beeps if you press the down arrow in the command window, and there are no more commands in the history.
At this point, I've given up, so I just disabled system sounds.
I have to say I'm surprised this is a total non-priority for the Mathworks. It bothers me so much that if I worked there, I would have fixed this myself, probably on my first day!

2) Turning off ALL warnings is a BIG hammer. Warnings, like pain, can be a
good thing that alert you to problems when they're small, before they turn
into bigger problems that cause errors.
If you want to suppress ONE warning or a few warnings, then use WARNING OFF
with the identifiers for the warnings you want to suppress.

I am running linux (suse) and for me typing
xset -b
from the terminal disable the internal beeps. Typing
xset b
will again reactivate it.

This post is rather old now, but I post my solution that worked for me since I wasted some time to get there, so maybe I can save others the hassle.
I am running Matlab on a linux system (suse). For me, typing
"xset -b"
in terminal disabled the beeps. Typing
"xset b"
again will reactivate it. For windows I believe the cmd equivalent is
"net start beep" and "net stop beep" to switch on and off.
Hope this helps!

dir('C:\Program Files\MATLAB\R2020b\toolbox\matlab\audiovideo\');
load("mtlb.mat");
sound(y);
y=y/10;
save("C:\Program Files\MATLAB\R2020b\toolbox\matlab\audiovideo\mtlb.mat", "y");
beep;
It should give a fainter and less annoying, yet audible, beep. I am not able to test, but I think it will work.
