Hvem vi er<\/h3>\t\t\t
Projektet havde deltagelse af en gruppe dedikerede mennesker, der kom fra audiologiske klinikker, universiteter, teknologisk service, og h\u00f8reapparatindustrien. Det var medicinske audiologer og otologer, ingeni\u00f8rer, konsulenter og audiologop\u00e6der. Nogle unge, andre mere erfarne. Nogle arbejdede p\u00e5 projektet p\u00e5 fuld tid, andre p\u00e5 deltid og med andre forpligtelser. Enkelte havde direkte erfaringer med h\u00f8reneds\u00e6ttelse og rehabilitering.<\/div>\n\t\t<\/div><\/div><\/div>

The aim of the present study is to assess daily life experiences of new hearing aid users and to explore ways to utilize these assessments in a follow-up situation. The approach is based on online reporting, where the patients over a period of two months \u201cswipe\u201d through 453 possible experiences related to HA use. Seventeen patients volunteered to register experiences for a period of two months, and participated in a follow-up interview, where the registered data were presented. Results suggest that data can shed light on the development within various categories of hearing aid experience and promote reflection on the hearing rehabilitation process.},

\r\nabstract = {The basic frequency selectivity in the listener\u2019s hearing is often characterized by auditory filters. These filters are determined through listening tests, which estimate the masking threshold as a function of frequency of the tone and the bandwidth of the masking sound. The auditory filters have been shown to be wider for listeners with sensorineural impairment. In a recent study (Christensen et al., 2017) it was demonstrated on group basis that the distortion product stimulus ratio that provided the strongest 2 f1\u2212 f2 component at low frequencies had a strong correlation to the theoretical relation between frequency and auditory filter bandwidth, described by the equivalent rectangular bandwidth (ERB, Glasberg and Moore, 1990). The purpose of the present study is to test whether a similar correlation exists on an individual basis at normal audiometric frequencies. The optimal 2 f1 \u2212 f2 DPOAE ratio is determined for stimulus ratios between 1.1 and 1.6, at fixed primary levels (L1\/L2 = 65\/45 dB SPL). The auditory filters are determined using notched-noise method in a two alternative forced choice experiment with noise levels at 40 dB SPL\/Hz. Optimal ratios and auditory filters are determined at 1, 2, and 4 kHz for 10 young normal-hearing subjects.},
