e2e wireless 2.0 - Bypassing noise & reverberation with wireless connections

Even more efficient than directional microphones for improving speech intelligibility in reverberant and noisy environments, wireless connections bypass ambient noise by picking up the “clean” target signal and transmitting it directly into the hearing instruments.

BestSound Technology is equipped with e2e wireless™ 2.0 and is thus compatible with the Tek™ Wireless Enhancement System.

This technology allows the Siemens Tek Connect remote control to employ Bluetooth functionality and be compatible with a wide variety of modern communication devices – even for CICs (Figure 8). For phones that do not support Bluetooth functionality, such as many landline phones, Siemens offers a Phone Adapter which can be plugged into the landline phone. The Phone Adapter converts the telephone signal to a Bluetooth signal that can be received by the Tek Connect remote control. With the Tek Transmitter, signals from any stereo or TV set can be received in stereo and without audible delay.>

Tek with e2e wireless 2.0 improves speech intelligibility on the phone for several reasons. It bypasses noise in the listener’s environment and offers a better acoustic coupling than with a microphone alone. Listening with both ears allows the user to take advantage of binaural redundancy and central integration which can improve the SNR by 2 dB. And, of course, listening with two ears assures that the better ear is always included. In fact, recent research has shown that listening on the phone with both ears improves the SNR by more than 5 dB (Ricketts & Picou 2008).
