“…One of the disadvantages of supra-aural earphones is the possibility of exhaust energy at low frequencies, because of not being very well connected; Furthermore, cause more discomfort due to the headband tension on the skull (3) . When compared to supra-aural, insert earphones to produce no pressure on the ear outer and the skull are more comfortable, generate greater reliability to the examination, have higher interaural attenuation and may reduce or eliminate the need for masking contralateral (4,5) , generate greater attenuation in environmental noise, allowing the realization of audiometric tests in non-isolated environments acoustically (6) , reduce the occlusion effect of the external ear canal in testing of bone conduction and reduce the risk of collapse of the external ear canal (7)(8)(9) . There are studies in the literature showing that there is a significant difference in the results obtained in the test and retest with the supra-aural and insert earphones, showing better results in the retest (10)(11)(12)(13) .…”
