One of the challenges with being close to an airport is that noise is transient.  The type of plane, direction of takeoff, and frequency of flyover events make a difference.  So, simply taking measurements once may not be sufficient to make good design decisions. And, while most airports have noise contours (basically, an average level), that doesn’t matter when you are in an office trying to make a phone call if you are doing it when the noise is decidedly above average.

We often place noise level meters on sites for weeks at a time to be able to get a picture of the reality of peak noise.  Having accurate information means the client doesn’t have to spend more in construction than necessary to achieve a quiet building.

And that often means walking miles through pastures or hanging out on rooftops.
