I know the jt4 was only an turbo jet and most jt4 powered jets was retired before I could tell the difference in jet engines sound. Did it sound like a more like jt3 or jt8 or did it have it own sound. If any body herd a B707 or DC8 powered by jt4, please tell they how sound?

Replying to your post very late, but nevertheless, here is an answer for you.
This is perhaps the one and only video clip of a JT4-powered DC-8 (series -20) aircraft, where you can at least hear a bit of the engine sound. Unfortunately, when it flies by, the engines are not revving that high, so it "appears" to sound quiet. But wait after the fly-by, and you can hear the muffled boom of the exhaust as the jet completes its wave and begins to climb.
