This claim is trivially true by definition and everyday observation, as the acoustic resonance of struck metallic objects (like bells or tuning forks) producing audible ringing is a well-established physical phenomenon requiring no citation.
The claim states a basic physical property of metallic objects vibrating at resonant frequencies when struck, producing sound (ringing). This is common knowledge and a matter of direct everyday observation and physical definition. None of the retrieved specialized papers specifically evaluate or test this basic premise as a primary research question, nor are citations needed for such fundamental facts.
