FreeBSD Disable Bell / Beep ( Hardware beep )

I know how to disable beep sound under Linux, but the settings are not working under FreeBSD laptop. How do I disable beep sound under FreeBSD operating system?

To enable or disable bell use MIB hw.syscons.bell under FreeBSD operating systems. Type the following command to disable for current session:
# sysctl hw.syscons.bell=0
Make sure settings remains same after you reboot the laptop, enter:
# echo "hw.syscons.bell=0" >> /etc/sysctl.conf
