The use of hearing aids (HA) is considered a predisposing factor for ear microbial infections. We undertook this study to compare the presence and nature of the microbial flora inhabiting of ears of HA and non-HA (nHA) users. Swab samples of the ears of HA and nHA users were collected from the Institute of Otolaryngology, “Cattolica del Sacro Cuore” University “Agostino Gemelli”, Rome, Italy. Swab samples were taken from the ear canal of 57 HA and 33 nHA users. The components of the microbial flora present on each swab sample were identified and characterized at the level of species.

Background: For many healthcare providers, tinnitus and hyperacusis are difficult symptoms to treat. There remains no conclusive cure for either symptom; however, helpful management strategies have been developed utilising counselling and sound therapy. Nowadays, most modern hearing aids have integrated sound therapy as a programable option; although, unlike hearing aid gain characteristics, output verification of sound therapy programs is not common practice.
