WebSuccess is measured by improved air conduction, improved speech discrimination, and more benefit from a hearing aid. In our surgical experience with 72 patients with far advanced otosclerosis, the average hearing gain was 20 dB, and 70% benefited more from a hearing aid.26. Discrimination was improved by more than 15% in 54% of cases. WebIt is difficult or impossible to obtain air or bone conduction threshold levels in some cases of moderately severe conductive involvement because it may be impossible to mask the nontest ear without also masking the test ear. This has been termed the "masking dilemma." In most of these "masking dile …

WebDuring bone conduction testing, a masking dilemma may occur when the air-bone gap of the nontest ear is greater than or equal to the interaural attenuation minus 15 dB ( ABGNTE ≥ IAAIR − 15 dB). Conclusion: Naunton's masking dilemma imposes a significant limitation to conventional audiometric testing. Web27 de ago. de 2024 · For bone conduction, the interaural attenuation may be as low as 0 dB because the bones of the skull are very efficient at transmitting sound. Thus, any suspected difference in bone conduction between the test and nontest ears requires masking. Interaural attenuation for air conduction can range between 40 and 80 dB. http://audsim.com/tutorials/maskingfiles/FormulaMasking1.pdf german government a350
