I have a vintage laptop that emits a very high frequency sound from the internal speakers (both sides) that borders on tinnitus. I haven't been able to find a replacement part to try and fix it, so I'm wondering if it would be possible to instead make a small circuit to cut off the extremely high frequency response from the output. Even if there is a small loss in fidelity, it would be hard to notice through the internal speakers anyways.
I don't think it's the speakers themselves, since they are stereo and I can hear it from both sides.
Can this be down with a small circuit?
My ears thank you.
