In Reply to: dynamic range of magnetic materials posted by dave slagle on November 12, 2003 at 19:20:05:
First of all, "dB" is a dimensionless (no units, a ratio) quantity, while kilogauss (kg) has units. Equating 20 kg to "86 dB" is valid only if "1.0 gauss" is understood as the reference. As far as dynamic range goes, the noise would have to measured or somehow determined. If the rms noise level is greater than 1.0 gauss, then the dynamic range will be less then 86 dB. A noise "floor" of 2.0 gauss gives a dynamic range of 80 dB, whereas 0.5 gauss of noise gives 92 dB. Does this clarify things? Best regards.
