The strike tone is not directly measurable but is definitely perceptible. Generally it can be found by setting an oscillator to match the perceived note of the bell. Multiply the oscillator's frequency by two and you will generally find that the result matches the measured frequency of the Nominal partial. We have tested this theory even on really bad sounding bells. It somehow always works.

The strike tone is not directly measurable but is definitely perceptible as a subjective harmonic. Generally it can be found by setting an oscillator by ear to match the perceived note of the bell. Multiply the oscillator's frequency by two and you will generally find that the result matches the measured frequency of the Nominal partial. We have tested this theory even on really bad sounding bells. It somehow always works.

When the ear-brain hears combinations of high tones, we think we hear a single lower tone. For instance a combination of a Nominal with an octave-Quint sounds like a single tone lower than them both. This may explain why Big Ben sounds to most listeners like an A even though it was cast to be an E.
