Full-digital signal processing chip
Use full-digital 2-channel 10 frequency technology computer programming, sampling analysis for singnal by three grade sigma-delta module, the sampling frequency up to 2.048MHz, to ensure that the A/D and D/A converter output to maintain high-fidelity signal, so listen to more clearly. Built-in intelligent silencing feedback system, easy to solve the acoustic feedback troubled.
Open DSP digital signal processing platform
Open DSP digital signal processing platform, direct offer hearing aid frequency response curve, and provide scientific basis for the fitting. The fitting is simple and convenient, use the POGO scientific computing formula, to ensure the best settings to more accurately meet the hearing loss.
Automatic volume control
The dual-channel independent use WDRC wide dynamic compression technology, automatic volume control mode, can ensure the voice amplification in a comfortable area, to achieve the best.
Ultra-fine 10 frequency band adjustable
Have 10 frequency band digital audio signal processing technology, can accurately compensate for specific hearing loss, in the process of fitting, like adjusting the digital radio, quick and effective to adjust to the most clear voice signal frequency band that the customer need, to meet the different frequency bands hearing loss requirements to ensure a coherent and natural sound in order to obtain higher satisfaction.
