What causes 1f sound?

1/f noise in current or voltage is usually related to a direct current, as resistance fluctuations are transformed to voltage or current fluctuations by Ohm’s law. There is also a 1/f component in resistors with no direct current through them, likely due to temperature fluctuations modulating the resistance.
