Help! Is there any way to eliminate the background noise on my audio file. It's a spoken lecture and the voice itself sounds okay but there is a lot going on in the background. Thanks!

Like Geoff said, Noise Gate - A good starting point is about -40 db then decrease it in -5 db steps, ie -35 db, -30 db etc until you get a good balance where none of your spoken word material is getting cut out by the gate and your background noise is significantly reduced.

Also, reducing high end eq with graphic/paragraphic/parametric eq etc. on spoken word you can probably roll off anything above 8 Khz (but obviously adjust this to taste as required).

Additionally, Noise Reduction if you have the Sony Noise Reduction plug-in or similar DX/VST plug in may help, run it through a couple of passes.

You may not like the sound of the gate opening and closing, especially on spoken word with background noise such as H/VAC. I perfer Noise Reduction with some downward expanding. The Dynamics> Graphic process can be confiqured for expanding.
Expanding allows you to adjust the ratio/amount of attenuation, where a simple gate just switches on & off, which is usually ok on drums and some other instruments but is very noticeable on speeches

I second the expander instead of the noise gate. EQ everything out below 100Hz (higher if the voice still sounds OK), and the really top end 10k. EQ can help notch out stuff, too and promote speech intelligibility. The Sony NR plug can work wonders, but I always try these things first.

Or Noise Reduction software.

Sony sells it (V 2.0) and Waves makes a great X series for X-Noise, X-Crackle, X-Humm, & X-Click.

I use Waves and it does the trick every time to elminate AC/DC crackle and humm.
