Compression in Hearing Aids: Why Fast Multichannel Processing Systems Work Well |
| |
by Edgar Villchur, MSEd |
| |
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. |

| |
by Francis X. Baur, AuD, and Thomas R. Zalewski, PhD |
| |
A study that looks at the attenuation value provided by a popular noise-cancelling headphone in the presence of high-level white noise, and a discussion of what this means in recommendations for hearing conservation. |

MPO: A Forgotten Parameter in Hearing Aid Fitting |
| |
by Francis Kuk, PhD; Petri Korhonen, MSc; Lars Baekgaard, MSc; and Anders Jessen, BSc |
| |
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 |
| |
by Patricia Gaffney, AuD |
| |
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. |
