Bash: Silence a process put into background

Question

If I run a application using the bash and I put it into the background via

• STRG+z
• bg command

If now the process is printing to stdout the shell prints this output. This output is not interesting for me and I do not like my shell to be polluted with it.

Is there a way to redirect the output form this process to /dev/null

I could have achieved the very same by directly starting the application in background with (./application &> /dev/null)&, but my application is already running and I would not like to quit it and restart it.

One option is:

1. Bringing the job to the foreground (see Job control).
2. Redirecting ouput (see below).
3. Sending to the backgrouond again.
