Mind the Ports! The Effect of Severe Microphone Inlet Occlusion

Sun, 1 Jun 2008 00:00 EST

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.

Compression in Hearing Aids: Why Fast Multichannel Processing Systems Work Well

Sun, 1 Jun 2008 00:00 EST

References in the academic literature maintain that flattening of the speech envelope by fast multichannel amplitude compression reduces speech intelligibility-references that typically ignore the counteracting effect of recruitment. A perspective from one of the pioneering engineers of compression in hearing instruments.

MPO: A Forgotten Parameter in Hearing Aid Fitting

Sun, 1 Jun 2008 00:00 EST

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

Sun, 1 Jun 2008 00:00 EST

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.

Lost in the Fog: Psychological Aspects of Adult Onset Hearing Loss

Thu, 1 May 2008 00:00 EST

Secondary trauma relative to hearing loss is not only about one's disability, or the loss of hearing; it's also about the insensitivity of others. In Paul's case, he felt helpless and angry—like he was trapped in a traffic jam with nowhere to go and with others around him going on their merry way. For some, like Paul, they find a way out through a productive outlet that refuels them emotionally.
