Electroacoustic Verification Measures with Modern Hearing Instrument Technology

چکیده
Modern-day hearing instruments offer a wide variety of signal processing options, including widedynamic range compression (WDRC), multiple channels, selectable compression speeds, dual/directional microphones, and noise detection. Similarly, modernday hearing instrument test systems offer a wide variety of test signals, varying in their bandwidth, spectral shape, level, and temporal characteristics. The process of verifying the performance of a given hearing instrument for a specific infant or child is therefore complicated by the process of matching appropriate test signal characteristics to the signal processing characteristics of the hearing instrument, in order to obtain an accurate test. In this chapter, we will review some current issues in electroacoustic verification of modern-day hearing instruments and we will outline some evidence-based strategies for verification with modern hearing instrument technology.

The Essentials of Fitting Hearing Aids to Babies
Fitting hearing aids to infants requires special consideration at each stage of the process. In the assessment stage, electrophysiological hearing threshold estimates must be adjusted appropriately so that an accurate hearing aid fitting can occur. Ear canal acoustics are also important to consider during the assessment stage of the hearing aid fitting process for infants. A strategy for measur...
متن کاملModified Verification Approaches for Frequency Lowering Devices
Providing effective hearing aid fittings for high-frequency hearing loss is a challenging and important clinical task. The importance of this task becomes even more apparent when considering the development of speech and language skills in the hearing-impaired pediatric population. Current research suggests that children require audibility of a broad bandwidth of speech for optimal access to hi...
متن کاملEffects of Electroacoustic Characteristics of Hearing Aids on Speech Understanding
Research under this contract is broadly concerned with the relationship between the electroacoustic characteristics of hearing aids and their successful use by the hearing-impaired. We seek the elusive link between the physical and the behavioral: the extent to which differences in electroacoustic factors affect the listener's ability to understand speech through the aid. The present report is ...
