I've d/l'd a few of the audio level meters provided at the Darkwood Design site mentioned by Carl312
Again, here's the link to that site:

If you install one of the level meters (I recommend Peak Level Meter Version 1.82) and place it "over" (always on top) the PD GUI or perhaps on another screen of an extended desktop, you essentially have level meters for audio reference.
However, who's to say what level is too much or too little? You need a reference level of 0db. I've attached a 1kHz tone wav & mp3 file that I use, but what's 0db on my system could be -4 or +8 on yours. This is not an error. Rather, it means you need to calibrate your system audio output volume to display 0db on the level meters.
Much like color bars in the broadcast world, NTSC color bars are/were used for viewing on a video waveform and vectorscope monitor. One would view the playback of color bars that are on a tape or digital media, then adjust proc amps and TBC controls so everything referenced the standard North American NTSC levels of luminance and chroma presented in the color bars.
So, get your Darkwood level meters on top of your PD GUI, import the 1kHz tone and play the clip (or drop it in your timeline and play the movie). While playing it, set your PD *System Volume [Ctrl]+U until the 1kHz tone reads 0db on the meter's L & R channels.
Then go about your editing, watching the audio levels of your media in the timeline and adjusting accordingly so the overall volume doesn't ride above 0db. Note that occasional 'hits' above 0db are okay, but in the world of digital audio, levels that peak aren't forgiven nearly as much as they were in the analogue days. Digital audio overdosing produces an undesirable series of "cracking" sounds, where analogue audio simply distorts.
*Setting the PD System Volume will alter the overall output to your PC's speakers or headphone. What's really going on with the VU meters is they are showing the output of the PC's audio, even though you can use PD's System Volume to do so. I recommend powered speakers from your PC (and likely most of you have them already), then using the volume level control on those speakers for your listening needs. This will not affect the 0db reference you've setup within PD because the external speaker volume control is (duh) downstream of your system/pc audio.
(hey, I wouldn't mind a video waveform monitor within PD
