It turns out I was a little low on the "acceptable" noise level. According to Massport's website: "65 dB DNL is a level the FAA says is incompatible with residential communities. Population exposed to levels of noise in excess of 65 dB DNL decreased from 9,438 in 2004 to 6,477 in 2005, approximately 31%."
Also, you need several noise monitors at different locations.
Plus you have to include the cost of a consultant to gather, compile and analyze the data, and to prepare a technical report to accompany the legal pleading. All of that costs much more than the hardware.
I dunno, though. It may be you could find somebody experienced and credible to do the work for less, especially in the current economy.
There's a picture on this Massport web page of the type of monitoring station they use:
