ElaraTek SonoKlara® Bluetooth Headsets Software Simultaneous Rx / Tx noise cancellation, acoustic echo reduction, speech enhancement, hearing exposure monitoring & alert, and music effects, optimised and ready-to-run on CSR’s BlueCore5-Multimedia. Baseband R A D I O Bi-directional noise reduction, speech enhancement, echo cancellation and noise-dependent auto volume control represent the core of SonoKlara® proprietary technology from ElaraTek. SonoKlara® identifies background noise mixed with the signal and intelligently auto-tunes the noise reduction algorithm in to cancel different noise types mixed with the signal, including: road/traffic/engine noise, street/factory/café/babble noise and wind noise. Subsequently the speech enhancement algorithm compensates for any adverse effects and the result is clear naturalsounding speech, even when background noise is dominant.

A2DP music enhancement bass-boost enhancement treble-boost enhancement rock and classic music effects User exposure monitoring & alert continuously monitors acoustic energy through the headset calculates accumulative hearing exposure in HSP and A2DP configurable loudspeaker setting for precise measurement notifies the user if a pre-defined acoustic energy level is reached notification message can be deactivated / reactivated Listening to loud music for extended periods of time through a headset can adversely affect human hearing. SonoKlara® offers sound exposure monitoring and alert to maximise hearing protection. ElaraTek’s comprehensive suite of voice enhancement technologies are optimised to run on Kalimba DSP. The Master Headset Application (MHA) is ideal for module selection, and speedy integration to deliver new products with unique features to meet customer requirements. Bluetooth Headsets VoIP Headsets Private Mobile Radio Call Centre Headsets Master Headset Application Aviation Headsets ElaraTek Software Call Centre Solution Enhance the performance of your call centre headsets by integrating technologies and solutions from ElaraTek. Our technologies offer speech clarity while protecting operators from excessive noise exposure and acoustic shocks. ElaraTek’s proprietary acoustic shock protection technology accurately identifies different types of acoustic shocks and subsequently attenuates the shocks without adversely affecting voice quality.
