Mind the Ports! The Effect of Severe Microphone Inlet Occlusion
Maintaining microphone ports, ensuring they are free from occlusion, is very important to the function of the hearing aid. Severe occlusion of the rear microphone port may produce values of greater than 15 dB of increased output for non-frontally arriving sound that is otherwise attenuated by the directional processing.
MPO: A Forgotten Parameter in Hearing Aid Fitting
It is important to select a hearing aid with a sufficiently high MPO such that the desired gain plus the input levels would not be limited by the MPO. The same considerations should also be applied to setting the MPO on a hearing aid in order to ensure maximum audibility and optimal SNR, while considering listening comfort.
Reported Hearing Aid Use Versus Datalogging in a VA Population
The objective analysis afforded by datalogging can provide the clinician with information to more effectively program the hearing aids and counsel the patient; however, the clinician is ultimately responsible for knowing how to use that information appropriately—particularly when there is a discrepancy between the user report and the datalogging.
What Helen Keller Knew; What Popular Thought Overlooks
An honest, realistic appraisal of the emotional and psychosocial challenges that beset a huge swath of the general public—those who have moderate to profound hearing loss. The fact that hearing loss has often been called an "invisible handicap" illustrates why so many people fail to recognize its impact on their lives.

More Than Meets the Ear in Successful Cocktail Party Conversations
New research shows that different speakers have different temporal fine structures in their voiced speech and that such signals are represented in different areas of the auditory cortex accordingly. By means of a so-called winner-take-all algorithm, one of these representations gains control over all other representations, meaning that only the voice of the speaker to whom you wish to listen is still represented in the auditory cortex and can thus be followed over time.
