Windows 10, PsychoPy 1.85.2.
I’m using the voice key to measure reaction times to reading a presented word. There’s some ambient noise in the room from ventilation, computer hum, people in the hallway outside. I’m using Audacity to try to run some spectral analyses so I can find the best band-pass filter and threshold to use.
Since audacity tells me the ambient decibels for each spectrum, it would be useful to know the relationship between the units of PsychoPy’s “threshold” kwarg and decibels. Does “threshold” have any interpretation as a number of decibels?
