Measure of amplitude #4

Closed hajarimanitra closed 7 years ago

Hello,

I played a sound back in a same condition, same volume then I recorded it at different distances. I was expecting the amplitude would decrease with the distance. However, the measurement said the opposite. Amplitude Mean was 22 at 1m and 30 at 15m. I was using the same settings for the measurements. To export the parameters, I compressed syllable measures. However, the same pattern occurred if I used the option uncompressed element measures (lower amplitude at closer distance and higher amplitude at farther distance). I was wondering if that is normal or if I did something wrong.

I am attaching screenshots of the sonograms and the result of the measurements. Unfortunately, I cannot attach the wav file here but I will be happy to send them to you if needed.
I am using the latest version 2.16.10.29.01

At 1m at_1m

At 15m at_15m
