A sound whistle blowing system is a critical component of good corporate governance. While public companies are required to meet SOX whiste blowing standards, private organizations, as well as small businesses, have also followed suit.
Previous answer: 1,729 MHz. There is no resonant frequency of gold. Gold does have an NMR frequency, which is 1.729MHz. All NMR frequencies are dependent on the ambient magnetic field, and gold's 1.729MHz is valid for a magnetic field of 2.35 Teslas, which is 45,000 times stronger than a typical Earth field strength.
We use mainly high-purity gold (Au), chlorided silver (AgCl) and sintered Ag/AgCl electrode materials. Gold electrodes are very robust and easy to maintain and provide a very good signal quality at frequencies above 0.1 Hz (not suitable for DC recordings).
