Being heard is good, but being consistent, obedient, and faithful is the baseline. After that, there was a rumble he did not create and Yahweh proved that He could make Himself heard.

Hear now, the word of the LORD.

Ezekiel 3:4-17: 
He said to me: Mortal, go to the house of Israel and speak my very words to them. For you are not sent to a people of obscure speech and difficult language, but to the house of Israel– not to many peoples of obscure speech and difficult language, whose words you cannot understand. Surely, if I sent you to them, they would listen to you. But the house of Israel will not listen to you, for they are not willing to listen to me; because all the house of Israel have a hard forehead and a stubborn heart. See, I have made your face hard against their faces, and your forehead hard against their foreheads. Like the hardest stone, harder than flint, I have made your forehead; do not fear them or be dismayed at their looks, for they are a rebellious house. He said to me: Mortal, all my words that I shall speak to you receive in your heart and hear with your ears; then go to the exiles, to your people, and speak to them. Say to them, "Thus says the Lord GOD" whether they hear or refuse to hear. Then the spirit lifted me up, and as the glory of the LORD rose from its place, I heard behind me the sound of loud rumbling; it was the sound of the wings of the living creatures brushing against one another, and the sound of the wheels beside them, that sounded like a loud rumbling. The spirit lifted me up and bore me away; I went in bitterness in the heat of my spirit, the hand of the LORD being strong upon me. I came to the exiles at Tel-abib, who lived by the river Chebar. And I sat there among them, stunned, for seven days. At the end of seven days, the word of the LORD came to me: Mortal, I have made you a sentinel for the house of Israel; whenever you hear a word from my mouth, you shall give them warning from me.
