Is the following image the section of a Resilient channel?

per this post,

Resilient channel is a thin metal channel that is intelligently designed to

substantially improve the sound insulation of drywall, sheetrock, plasterboard walls

and ceilings. The channel effectively isolates drywall from the framing studwork,

which results in the weakening of sound waves substantially.

Is the following image the section of a Resilient channel?

The key is the air space at the right side, which cannot be connected to the connect studs. Is my understanding right?
