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 )

    If I play a sound from a driver on my left, and the noise is from a device on my right. I believe they will not cancel out and I will hear two noises on each side of my head. My head will act like a shadow to the wave front as it propagates right? I suppose one could build a device to play the sound at the drive, but that is a bulky solution.

    I was asking about passive damping here, not that I mind the tangent.

        Pain is due to neck and back. So the root of the problem is the weight of my head, and why I’m stuck in bed in the first place. I have some noise canceling headphones already, but between the weight and positional constraints they cause they are an issue. It isn’t a real problem because I usually do not leave the thing on or plugged in. I have been doing so lately because I have needed to test a lot of AI models with Emacs looking for the most capable, with thinking and function calling, and the largest available context, along with others that can be switched in an agentic system and are more capable and potentially specialized with my own fine tuning.

        I should just get another larger NVME drive, but purchasing anything right now sounds stupid.

          Okay.

          Completely different track.

          I’m assuming that this drive is connected by USB.

          Sound attenuates with distance.

          Plug in a longer cable and put it further away?

          Or move to ethernet and put it in another room?

            Could, but then I lose portability like with mounting it in my laptop stand.

            Everyone here seems to want to solve everything but the actual abstraction of wanting to know a way to calculate a thin liner material to add to the portable box that is not reliant solely on empirical brute force.

            If someone else asked, I’d be saying the same things. It is easy to assume people can replace such knowledge with empirical testing and observations, but when the physical efforts become harder, working smarter has value to me.
