sensogram the sensogram is one of the most efficient and precise fitting methods available by measuring the hearing threshold of the wearer with the hearing aid properly positioned in the ear variations in real-ear spl are eliminated compared to traditional audiogram-based fittings the basic sensogram is performed at 500 hz 1 khz 2 khz and 4 khz for more atypical losses the sensogram can be measured in up to 14 frequency bands the test signals used are frequency modulated tones with the maximum frequency deviation automatically set to the critical bandwidth corresponding to the center frequency of each band diva compression senso diva has an enhanced dynamic range compression edrc system implemented in each of the 15 channels the frequency gain-response for conversational level is determined by providing appropriate gain to each frequency region so all are equally and comfortably loud for optimal intelligibility i.e loudness equalization louder and softer sounds are amplified accordin

graph below level distribution function of speech signals diva locator diva locator uses a dual microphone system that continuously matches both microphones in phase and amplitude this effectively eliminates the problems related to microphone mismatch while maintaining good directional performance over time in all frequencies diva locator is an adaptive beamforming system that continuously and automatically estimates the location of noise sources in order to minimize their magnitude the optimal microphone characteristic is adaptively controlled and its polar pattern changes from omnidirectional to cardioid supercardioid hypercardioid and bidirectional depending on the location of the noise source the noise classification unit analyzes the incoming sound and continuously adjusts the polar pattern best suited for the particular situation in some situations such as wind noise and listening in quiet the hearing instrument will smoothly adjust itself to an omnidirectional pattern in order

music program activates the microphone and is intended for typical use m t activates the t-coil and is useful for inductive signals and t activates both m microphone in omni-directional mode and telecoil the music program is a preprogrammed option derived from the original fitting with all signal processing parameters further optimized for enhanced music appreciation back to top
