try non-reverbed, synthetic sounds #8

[ ] get acoustically transparent vocalizations from chicken wire experiment
[x] try finding vocalizations from other species in already acoustically transparent conditions
[x] is there a metric to quantity reverbiness?

re: reverbiness. Need to quantify the RT60 (reverberation time in seconds) using Sabine's formula.

However, this depends on knowing the sound absorption coefficient of plastic at frequencies relevant to us (from ~1 kHz-60 kHz). It doesn't look like the absorption coefficients are documented for sounds above 4 kHz. (https://www.acoustic.ua/st/web_absorption_data_eng.pdf)
