A--------Automatic G-----------Gain C----------Control.
It's an old technology, but this external gadget is new on the market and I don't know the company who makes it!!

I installed a professional product in a commercial application called Symantec that did what you ask. It had a microphone you placed in the room, and it monitored ambient noise. Since the device went between the preamp and the amp, it could adjust appropriately.
The device I boought was mono, with a stereo option available by buying a second sidecar module. Cost was high, but it worked great in the upscale restaurant I installed it in.
Bogen makes a model along the same line, but I have no experience with how well the product works.

Audioplex used to make a device like this, although I don't see it on their site anymore. Maybe they have some old stock... I'd email them and ask.

You could just use an audio ducker or compressor/expander with a mic preamp on the sidechain input.
You plug a microphone into the sidechain which works as an ambient noise sensing mic. On a compressor or ducker that allows an inverse compression ratio you can set it so the volume raises when a loud input signal is heard through the sidechain.
A bit of research is needed around the makers of cheap professional audio processing equipment - behringer for example might have the right item for you.
Obviously a decent DSP based audio processing system will let you programme very specific conditions for how and when volume is altered but this costs a lot.

O, the unit you posted is a straight compressor. Dale wants a device that reduces the compression when ambient noise level increases. That would require a microphone, and, logically, the ability to ignore the desired audio, to avoid a runaway situation. Larry www.fineelectricco.com
