a aoc disabled b aoc enabled measurements the advanced signal processing algorithms used in senso make results of direct conventional measurements variable and difficult to interpret special considerations are necessary in making these measurements for quality control and service purposes a special test mode has been defined that allows inspection of the electroacoustic integrity of the hearing aid s components the test mode can be accessed from both the lp2 programmer and the compass software loudness mapping loudness mapping uses an advanced automatic volume control function to provide audibility and comfort for most sounds compared to linear hearing aids soft sounds are amplified more providing a lower aided threshold and loud sounds are amplified less reducing listening strain the widest possible range of sound is preserved within the wearer narrow dynamic range s unlike typical wdrc systems which use fast regulation time to achieve a nonlinear gain function loudness mapping uses

sound stablizertm applies dynamic control of the regulation times this yields steady gain in stable environments and rapid gain adaptation to drastic changes in the acoustic environment amplification reduced after a loud noise for instance will quickly return to ensure audibility for soft sounds automatic feedback manager senso is equipped with an automatic feedback manager in each of the three frequency channels it determines how much gain is possible without feedback and limits the maximum gain accordingly this will not influence amplification of normal speech sounds the automatic feedback manager can be adjusted manually to control the kneepoint of the input-output function this affects gain for the very soft sounds it can be used to help new wearers to acclimatize to hearing soft sounds again with reduced amplification initially this process is described in our programming manuals speech enhancement one of the main difficulties for hearing aid wearers is understanding speech in noi

time to replace the cell telecoil the telecoil and the microphone in senso have separate a/d converters this allows filtering of the inductive input without any analog pre-amplifiers that is why senso can offer both equalization of the telecoil response so that it has the same sensitivity as the microphone and an anti-hum filter to reduce interference from the line input the sensitivity of the telecoil is adjustable this will enhance the benefits from the telecoil when used with weaker inductive loop systems programming all senso hearing aids can be programmed with the small hand-held lp2 programmer and the hi-pro interface with the noah compatible compass software please refer to the programming manuals for details back to top
