Is there any meditation technique to be aware of what you hear?

I have observed that while meditating if I turn my awareness from breath to 'what I am hearing' I have a heightened sense of present moment awareness. If I listen mindfully to what I am hearing the mind invariably comes in present moment. As the hearing can only happen in present moment. Also, I see that there are foreground noises and constant background hum, like a low-frequency sound in the background. I want to ask is there any meditation technique in Vajrayana or any other Buddhist tradition to remain aware of the hearing and transcend the sense spheres thereby? If yes, what is it and how to practice it?
