my grandma has a 1997 S320 and while driving, every once in a while i'll hear 4-5 second lights buzz/humm that never happened before until just recently/ it doesnt affect the car and mercedes doesnt know anything so can anyone help or give meh some ideas? its not affecting the car, but i'm worried on how it may since it is a newer sound within about 6-8 months.

Try changing / topping up the power steering fluid, the pump can make some trange noises in the level is low or needs a fluid change, these noises can be transfered through to the steering column as a high pitched vibration or buzz.

Good luck

No my grandmother is very hip. also drives a SL63 with full boody kit and 22's lol. so it caint be a hearing aide, but the best way to describe the noise is an automatic cutting knife going really fast (but not very loud) cutting through the thanksgiving turkey. it's not like a horrifying noise or sounds like anything cracking and grinding. and it does it when i'm just driving straight, not while i'm turning or anything. when i have the radio up at med/hi you caint hear it, at medium volume u can faintly hear it, and at low of off, its noticable.
