Audio control meter with the suction cup stand. Or old dB Drag mic setup.was a round oarnge suction cup thingy that locked down and a mic that faced the windsheild was on passenger side
Reads about 6 dB higher than the TermLab when its calibrated. If they just dusted it off it is most likely not calibrated so it can be way off. Basically that reading does not mean anything. Sorry to say.
BTW. The TermLab is 5 years old this month.
