Humming/Vibrating Noise from under car

Ok guys heres the deal, whenever I’m driving nowadays, I hear this loud humming that oscillates in volume,up and down ya know. My question is this most likely a suspension problem or something else? I havent had my cd player for about a week and this noise is getting annoying. Has anyone experienced this before? I can feel coming from like right under my feet. All help would be appreciate guys, thanks.



describe what ya doing when the sound comes…going over something, going straight…
