If the Hum Test demonstrates strong sensitivity and specificity in detecting conductive hearing loss, it could have application as being utilized as an alternative to the standard Weber test, or in a setting where a formal physical examination may not yet be possible but where the etiology of a patient's hearing change could be quickly assessed remotely and thus the urgency of intervention/ consultation could then be determined.
