Audiometric asymmetry and tinnitus laterality The Laryngoscope, 04/13/2012
Tsai BS et al. – An optimal audiometric asymmetry index to predict tinnitus laterality is one whereby 15 dB is the minimum average interaural threshold difference (aITD) of two adjoining frequencies, inclusive of the maximal ITD. Tinnitus laterality dependency on magnitude of interaural asymmetry may inform design and interpretation of neuroimaging studies. Monaural acoustic tinnitus therapy may be an initial consideration for asymmetric hearing loss meeting the criterion of aITD 15dB.
