Current Issues In Probe Tube Microphone Measurements
In many ways, the field of real ear measurement is still in its infancy. While it is true that computerized probe tube microphone systems have gained acceptance and are being used fruitfully with all patient populations, there are many subtle features and test protocols which are still poorly det1ned. Other than the issue of terminology which seems to be changing monthly, the following are some...
متن کاملTracking multiple talkers using microphone-array measurements
A method for tracking the positional estimates of multiple talkers in the operating region of an acoustic microphone array is presented. Initial talker location estimates are provided by a time-delay-based localization algorithm. These raw estimates are spatially smoothed by a Kalman filter derived from a set of potential source motion models. Data association techniques based on the estimate c...
متن کاملMicrophone Array Measurements on Aeroacoustic Sources
The flow around obstacles is often very complex, leading to distributed aeroacoustic sources. In experimental investigations, microphone arrays can help to separate, analyze and quantify these partial sources. In order to do so, a microphone array with a high spatial resolution and a high dynamic range is essential. In this publication, the setup and application of a microphone array for aeroac...
متن کاملProbe-microphone measurements with body-worn instruments: loudspeaker and reference microphone effects.
Probe-microphone measurements are typically made with behind-the-ear (BTE) and in-the-ear (ITE) hearing aids with the loudspeaker located at 0-degrees or 45-degrees azimuth at head level and the reference microphone positioned on the head near the hearing aid microphone. With body-worn instruments, these conditions may not accurately reflect in situ hearing aid performance. This study compared ...
متن کاملEffect of reference microphone location and loudspeaker azimuth on probe tube microphone measurements.
The effects of loudspeaker azimuth and reference microphone location on probe tube microphone measures were assessed. The real ear unaided response (REUR), real ear aided response (REAR), and real ear insertion response (REIR) were obtained on a KEMAR. Aided measures were obtained with both a behind-the-ear and an in-the-ear hearing aid. All three measurements were affected by changes in the lo...
