Abstract Objectives Hearing in noise test (HINT) is used to evaluate and compare the performance of different hearing aid. This research was designed to compare the performance of a fixed directional microphone (FDM) and an automatic adaptive directional microphone (AADM) with different noise directions using aided Arabic HINT. Methods Control group (CG): 20 normal peripheral hearing adults. Study group (SG): 40 adults with bilateral symmetrical sensorineural hearing loss. Arabic HINT was performed in three noise situations at 0°, 90°, and 270° azimuths for both groups. For SG, test was done in 4 conditions: condition (I), without hearing aid; condition (II), aided response with omnidirectional microphone; condition (III), aided response with FDM; and condition (IV), aided response with AADM. Results For all azimuths, there was a statistically considerable difference between CG and SG in all conditions. Also, there was a statistically significant difference between SG conditions I and II and II and III. But no statistically significant difference was observed between conditions III and IV when the noise was at 90° and 270° azimuths. Conclusion AADM is the best choice of selection in hearing aid fitting, and it performs better in noise, especially when the noise and speech are in front of the patient. |
