I am working on a survey which requires the participant to listen to an embedded audio. I would like to know if I can obtain their device volume while on a specific page, or, even better, if it is possible to know the absolute volume range of the audio output on each participant's device while playing the embedded audio.

Hello @chunkyu_lee I guess that won't be possible as any browser made by Microsoft/Google/Apple/Mozilla/Opera doesn't allow this to avoid exploits through File.IO and limit developer's access to user's machines.

This is something you'd have to do in a controlled environment in order to trust your data is valid. For example, do you have any sort of physical location that you can control, like computer lab at universities or a conference room in a company?Depending on the population requirements you have, you could even try doing this in some sort of public (or willing private domain), like park (or mall/coffee shop). The only way you would be able to trust your data is to verify the volume levels before and after each response session. This is not an element I would trust to self-reported data.
