The ear canal volume (ECV) was at 1.6cc bilaterally which is normal for Dave’s age.
The Acoustic Reflex Threshold (ART) were tested at 500 Hz, 1000Hz, and 2000Hz. There was no indication of inner ear problems at these frequencies. Left Ear Right Ear
@500 Hz 85 dBHL 80 dBHL
@ 1000 Hz 85 dBHL 85 dBHL
@ 2000 Hz 85 dBHL 90 dBHL
Recommendations
Dave’s problems are consistent with a noise induced hearing loss (NIHL). When looking at the results that were obtained by an otoscopic exam, pure tone audiometry, speech audiometry, and immittance audiometry, it is evident that there is no medical treatment will improve his hearing. I recommend staying away from loud noises and using hearing protection that fits correctly in his ears. Due to the rest of his hearing being in the normal range except at 4000 Hz, there is no need for hearing aids at this time. Yearly check-up will be made to watch his
