The sensitivity and specificity of the Hum Test is being investigated in it's ability to detect conductive hearing loss. The hum test is simply elicited by asking the subject to hum to him or herself for a few seconds at both a high and low pitch that is comfortable for the subject. The subject is then asked if the hum was heard on one side more than the other (left or right), or if the sound was equal on both sides. To simulate conductive hearing loss, ear plugs will be placed in one of the subject's ears. We will elicit the hum test as well as the standard Weber test and audiogram across two conditions, with an ear plug and without an ear plug. From this, it is hoped to assess how the Hum Test compares to the audiogram (gold standard) in detecting conductive hearing loss as well as how it compares to the standard Weber test. 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.
