Signal processing delay is the time it takes for the hearing aid to process sound through its circuits. In a monaural or open fitting, unaided sound can reach the ear faster than it can travel through the hearing aid, potentially causing localization problems or “echoing” effects. In some cases, the digital signal processing delay of the hearing aid can be up to 15 ms, although more commonly it is in the range of 3-6 ms. Phase is a measurement of how the hearing aid pushes and pulls sound through the receiver of the hearing aid. For a pair of aids in a binaural set to be working properly...

before the coupler measurements are taken. This makes our measurements extremely fast because the feedback microphone does not need to be part of the measurement system. The leveling system also has the added feature of not interfering with the measurement of popular open fit hearing aids. In a feedback system, the open fit hearing aids can interfere with the feedback microphone measurement and thus decrease the accuracy of the test. However, with our leveling system, there is no possibility of this occurring. New AutoDetect Battery Simulator Pills These new pills (#675, #13, #312, #10)...
