Looking at the montages of the available data sets 2 include a snore channel, but it's sampled 100-300 Hz. Low Hz like that isn't actually audio, more just an indication of the existence of sound. I'm working on a project that analyzes audio to detect apneas and hypopneas. I don't know the exact Hz I need for my analysis, but I suspect 300 Hz is too low.
Have you seen any datasets with a corresponding audio signal of significantly higher Hz?
I am not familiar with any datasets like that. I will ask a couple people here who know more about our PSG archives to comment if they have any insight.
The NSRR does not currently have any datasets with snore channel sampled at >300 Hz. Additionally, I believe the snore data captured is vibratory snore through either the pressure transducer or via an EMG snore sensor, depending on the study.
Thanks @mrueschman and @DanMobley. It seems like maybe 20% of sleep labs record simultaneous audio. I'd be up for working directly with a lab if you know of any who record audio and participate in research.
