Hello Ashley, thanks for answering.
What I am suggesting is that Construct automatically applies the formula 33*log10(percent/100) to the value entered by the user when he chooses the "Percent (%)" option in the dropdown list, and thereby he obtains a perceptual result, i.e. a result that the human ear perceives as balanced in relation to the value entered, between 0% and 100%.
For this reason, at the end of the action description, it would say something similar to this: "In percentage, a formula is applied to provide a perceptual result."
In this way, the user would have the option of setting the sound volume in a more friendly and intuitive way, but without eliminating the possibility of entering the value in decibels for those who prefer it.
That's why I suggest that both options be available in a dropdown list.
Best regards.
