Regarding the charts -- I don't understand why they show both positive and negative decibels.

They don't. At the top and at the bottom there is both -3db. Its a simple waveform-display over time with negative db on the y-axis.

If you have some experience with such standard displays of sound, you can get a pretty good idea about the loudness-distribution. To get also an idea, which is more "annoying", an overlayed display of the frequency-distribution would help very much, a.k.a. fourier-transformation.

Very nice idea for a thread, though.
 
Yesterday I started a highly sophisticated scientific research project 😉

Visible clicks - shuttersound made visible! I mounted a microphone on top of my cameras (mostly in the flash shoe, where available), set the shutter to 1/60 (where possible) and recorded the sound.

The most amazing and unexpected result: some are louder than others 😀

Enjoy! Some more to come (5 per day)

What software do you use ? I'd like to use it and see if I can measure the various actions performed by the shutter curtains.
Thanks

I used WavePurity, but most sound recording software should do. Then I made screenshots and imported them in Irfanview

I believe WavePurity can show a fourier transformation, but only while the sound is on - so I cannot take a screen shot.
I am far away from my PC now on vacation, but I will check it when I get home.
 
Once upon a time...in a photo mag

Once upon a time...in a photo mag

'Way back in the Seventies/Eighties one of the US photo magazines (either Modern or Popular Photography) began publishing similar noise-graphs for cameras being reviewed. I think they kicked it off by showing an array of cameras already well-known & used, to give a baseline for comparison. Can't recall if it was Herb Keppler & Co. or somebody else. It was the dominant-heyday of the 35mm SLR and the spoilers of the whole show were the rangefinders (M4 maybe?) and TLRs.

I was photographing graffitti in a parking lot recently, with a Nikon S3. Ten-twenty yards away was another photog, using a big DSLR. With the shutter "sound effect" thing on, I could here his about as well as I could hear mine. Go figure. Reminds me of the big American cars from the late Fifties that had eight fake exhaust pipes coming out of either side of the hood (bonnet?). Go figure.
 
Heh.. I would love to see an X100 tested. I think the action of pressing the shutter mechanism is actually louder than the leaf shutter itself. In fact I've actually enabled the 'fake' shutter sound on mine on a very low level so I can have some sort of audio confirmation when the shutter goes off.
