Two recent developments (and I’m only slightly bitter that I had to find out with the rest of the common people).

• The FTA’s revised Transit Noise and Vibration Impact Assessment guidance manual has been released. Biggest changes seem to be the inclusion of train horns/whistles into the noise analysis and revised vibration critieria for detailed analyses. Available here or here.
• My favorite microphone manufacturer has released a new microphone designed for use in a Blumein configuration using a custom mount. Just in time for AES San Francisco! While you’re checking out the mics, you should also check Soundwave Research’s blog - lots of great info about acoustic design, manufacturing challenges, medical devices, history, and Bob Crowley’s unusual, err, esoteric hobbies. (just kidding Bob, the recorder cum shakuhachi sounded great!).

I didn’t even get any advance notice… I feel so out of the loop.

Quoted for truthiness: a response from Ken Plotkin on a common question posed to all acoustical consultants:

I think that the most important thing to be learned from your reply is that there is no general answer and that the applicable answer depends on the specifics/details of the situation.

That’s true about so many things. That’s also why the best answer to so many of the “How do I solve a noise problem” posts is “Hire a local consultant.”
