Hi All,
Today, for fun, I used a sound meter app (Decibel 10th by SkyPaw) on my iPhone to measure the sound level in my -4. Much to my surprise, the sound level averaged 96dB with a peak of 99dB. I had expected a value in the 80's... (Thank God for Lightspeed headsets) Has anyone else measured sound levels in their cockpits?
For comparison purposes, my -4 has an IO-360, 4-pipe Vetterman exhaust, and no sound proofing. I was running 23-squared while I held the meter (phone) at chest height during the measurement.
Thanks,
