Monitoring the sounds that power lines make

Advanced Integrating Sound Level Meter 

Quest's 2900 Type 2 Integrating datalogging sound level meter lets you use one instrument to analyze 'A', 'C', or linear weighted sound levels using a choice of exchange rates. Using 1/3 or 1/1 octave band studies, integrating all the information together in one file is easy. Create and store multiple files without having to print or download the instrument. Data will stay in memory, even if the instrument is turned off or the 9v batteries are removed. The optional OB-100 octave band filter set conforms to the most stringent requirements of IEC 225 and ANSUI S1.11, order 3.
