Testing Human Estimation of RT60 Using Photographs (for Comparison Against an AI's Estimation)
I’ve been working on an AI designed to determine RT60 based on photographs and now I need to find out what is more accurate, the AI’s estimate or a human guess?

Within this 4 minute survey you will be presented photographs of classrooms, which are the greyscale and not-high resolution images the AI is given, and you will be given 12 images per room to use to estimate the RT60 of the room at 500 Hz. There are three rooms to guess RT60 for in total.

This survey contains demographic questions and does not ask for any identification; all responses are anonymous. Please answer all questions honestly and independently to help improve the validity of responses and be aware that not all questions need to be answered to complete this survey. Thank you!
