If I know the frequency and magnitude of a high pitched continuous sound, how can I calculate the potential effects of damping materials? (lemmy.world)

I have a small hard drive that is making a constant high pitched sound that is typical of the drive, and not very noticeable to the average person, but I have pain induced noise sensitivity. I am curious about how to calculate damping potential. As an initial guestimate, the frequency is very near to my maximum audible range and likely around 12kHz-16kHz. It is a little higher than the switch mode power supplies that I can also hear if it is dead silent in the room, although the drive is a higher amplitude. Addressing the noise with a solution is probably beyond the scope of anything I would actually do, but knowing how to solve it is far more interesting to me. (ELI15 )

I would look up DIY sound dampening/absorption panels. The sound you're hearing isn't just from the source to your ear, it's also bouncing off everything in the room. If you make those surfaces "break up" the wave, they will be attenuated sufficiently by the time they reach your ear.

But also, as yourself if the materials and effort you go through to solve this is worth more than the cost of a different hard drive that doesn't make the noise.
