Smartphone-based tinnitus matching: Implementation and Validation

Tinnitus has been described as the conscious awareness of a tonal or composite noise for which there is no
identifiable corresponding external sound source, and is experienced by 15% of the European population. Tinnitus
may be experienced in one ear, both ears, or perceived as originating from within the head. It can present as
tonal sounds, noise-like sounds, or a combination of both. The perception can lead to emotional and/or cognitive
dysfunction, autonomic arousal, behavioural changes, and/or functional disability. There is no standard test for
tinnitus in the medical literature; audiologists typically test pitch (to within half an octave) and perceived loudness
of the pitch using standard clinical equipment for testing hearing loss. The underlying causes of tinnitus are not yet
fully understood, and more effective treatments are needed. We present the first release of an extended Tinnitus
matching app that includes a highly individualisable tinnitus pitch-matching tool and a comprehensive questionnaire
for mobile health tracking. The app facilitates large data collection on tinnitus sounds across aetiologies, cooccurring
symptoms, and demographics. Our intentions are threefold: 1) to provide those experiencing tinnitus
with a way to communicate what they hear more precisely, 2) to understand how tinnitus sounds vary across
demographics and how these relate to co-occurring symptoms, with a view to 3) providing a means of individualising
sound-based therapies. We
