IN AN earlier study, Graham and Newby5 reported that the pitch of tinnitus associated with a conductive hearing loss differs significantly from the tinnitus associated with a sensory-neural hearing loss, the former composed of low frequency tones. The tinnitus which accompanies Meniere's disease has been described as a low-pitched buzz or roar.1,3,10 Day3 has indicated the importance of ascertaining the pitch of tinnitus in the diagnosis of the disease, stating that it is usually between 100 and 300 cycles. However, no published research could be found reporting measurements of the pitch of tinnitus accompanying Meniere's disease.
The hearing loss which accompanies Meniere's disease is commonly classified as sensory-neural, cochlear, or perceptive. Certain investigators have suggested the possibility that the loss may be "inner ear conductive."8,9 There are two factors which influenced the origin of this theory. First, in the early stages of the disease the audiometric
