Electroacoustic Assessment of Wireless Remote Microphone Systems

Stochastic Threshold for Spectrum Sensing of Professional Wireless Microphone Systems

In recent years, the professional wireless audio transmission systems such as Program Making andSpecial Event (PMSE) devices have been risen causing the need for a higher spectrum efficiency. Cognitive radio (CR) paradigm has been proposed to maximize the audio quality and ensuring interference free operation all the time. The motivation to a reliable spectrum sensing (SS) technique for the det...

Considerations on the frequency resource of professional wireless microphone systems

This Paper presents the results of spectral observations in the UHF TV Bands IV and V from 470 MHz up to 862 MHz with focus on the TV-Channels 61 to 63 and 67 to 69. Concerning the discussions on WRC (2007) this frequency range is in great demand of several applications and is usually treated as a ”white space” in the TV-Bands. According to typical scenarios, two different spectral loads will b...

Wireless Remote Monitoring of Cathodic Protection Systems

Evaluation of a wireless remote microphone in bimodal cochlear implant recipients.

OBJECTIVE To evaluate the benefit of a wireless remote microphone (MM) for speech recognition in noise in bimodal adult cochlear implant (CI) users both in a test setting and in daily life. DESIGN This prospective study measured speech reception thresholds in noise in a repeated measures design with factors including bimodal hearing and MM use. The participants also had a 3-week trial period ...

Phonak CROS II - Electroacoustic measurements look at key performance aspects of two wireless CROS systems

The Contralateral Routing of Signal (CROS) device is one recommended solution for individuals with Single-Sided Deafness (SSD). BiCROS is the adaptation for individuals who also need amplification in the better ear. Phonak Audiology and Research Center (PARC) took an in-depth look at the sound quality, sound cleaning and general usability of the Phonak CROS II compared to a competitive CROS dev...
