Buy the termlab but I have a problem sensors do not measure evenly, there is a difference of nearly one 1db placing a sensor on top of one another in the same position, I find that it is much variation of the decibels, the sensor is in the channel this top 1 db Channel b probe changing cables, and lap position sensor, the other issue that I see is that when connecting the voltage of 2 sensors in a way that dbdrag above the other is normal that, I hope response

you cant measure that way you have to go side to side- depending on the car. most cars the slope greatly changes vertically and spl changes by a nice margin.
Place the sensors with the cord away from each other and center the measure mark evenly between the 2 sensors.
another thing is to check to make sure the K factors match whats on the sensors.
