Abstract
It is suggested that the evaluation of hearing for hearing aid selection should include measures of acoustic reflex thresholds. These thresholds should be examined in relation to the puretone and speech audiograms to confirm the need for amplification limiting and the selection of the best ear for a hearing aid if only one aid is to be provided. Middle-ear impedance measurements should be used routinely for hearing evaluation and only a few minutes are needed to determine the acoustic reflex thresholds. Måling af tœrsklen for den akustisk udløste mellemøremuskelreflex bør indgå i de undersøgelser, som benyttes ved udvœlgelsen af høreapparat. Reflekstœrsklen—sat i relation tœrsklen ved almindelig toneaudiometri—og den taleaudiometriske kurve bekrœfter patientens behov for output begrœnsning (f. eks. i form af kompressor høreapparat) og er tillige vejledende ved valget af det bedst egnede øre, såfremt der kun skal tildeles eet høreapparat. Det anbefales, at impedansmåling benyttes rutine-mœssigt ved bedømmelse af hørelsen, og det tager kun få minutter at bestemme reflekstœrsklen.
