Some issues are due to hearing instruments that are not optimally adjusted, while others are the result of the inexperience or misconceptions of new hearing instrument wearers. This document is intended to provide introductorylevel guidance on some of the most common issues and their resolutions using Hansaton instruments and the Hansafit fitting software. Many common complaints can be handled well with the Fitting Assistant, which describes many specific listening situations and issue resolutions. To access the Fitting Assistant, Go to Expert Tuning and find it under Details (Gain and Compression). Find the situation and complaint most similar to your patient’s report. Using this simple tool will often resolve the issue with a couple clicks of the mouse.

Common  Programming  Issues  and  Resolutions  

Hansaton  Acoustics  

As  a  hearing  professional,  you  encounter  the  daily  challenge  of  resolving  issues  presented  by  your  patient.    Some  issues  are  due  to  hearing  instruments  that  are  not  optimally  adjusted,  while  others  are  the  result  of  the  inexperience  or  misconceptions  of  new  hearing  instrument  wearers.    This  document  is  intended  to  provide  introductory-­‐level  guidance  on  some  of  the  most  common  issues  and  their  resolutions  using  Hansaton  instruments  and  the  Hansafit  fitting  software.    

Many  common  complaints  can  be  handled  well  with  the  Fitting  Assistant,  which  describes  many  specific  listening  situations  and  issue  resolutions.  To  access  the  Fitting  Assistant,  Go  to  Expert  Tuning  and  find  it  under  Details  (Gain  and  Compression).    Find  the  situation  and  complaint  most  similar  to  your  patient’s  report.    Using  this  simple  tool  will  often  resolve  the  issue  with  a  couple  clicks  of  the  mouse.  

 

 

Although  the  Fitting  Assitant  has  many  detailed  issue  resolutions,  there  are  a  few  that  seem  to  come  up  often  enough  that  we  would  like  to  have  some  easy  steps  to  handle  them  quickly.  The  following  are  our  top  issues  and  suggestions  for  quick  fixes.  

 

 

Common Programming Issues & Resolutions

2    

1. “It  just  doesn’t  sound  right.”    a. Counsel.  This  is  a  very  common  report  from  first  timers  and  experienced  hearing  aid  

wearers  using  new  amplification.  Reassure  them  that  time  and  patience  are  essential  to  adjusting  to  a  new  sound.  

b. Repeat  First  Fit  with  a  different  prescriptive  formula.  If  you  started  with  ExpressFit  (which  we  suggest  always  starting  with),  changing  to  NAL-­‐NL1  or  NL2  will  increase  high-­‐frequency  gain.    

 c. Expand  dynamic  range  by  

i. Increasing  gain  for  high  inputs  (Express  Tuning  or  Expert  Tuning).  ii. Decreasing  compression  ratio  (Expert  Tuning  CR1  or  CR2).  iii. Setting  aid  to  linear  operation  (CR=1.0).  This  option  is  perhaps  best  reserved  for  

experienced  hearing  instrument  wearers  who  have  no  issues  tolerating  amplified  sound.  

   

d. Adjust  balance  between  low  and  high-­‐frequency  gain  (Expert  Tuning).      

2. Speech  is  not  clear.  a. Follow  detailed  instructions  in  the  Fitting  Assistant  which  are  customized  for  specific  

situations.    b. Increase  high-­‐frequency  gain  c. Increase  gain  in  major  speech  frequency  range  (500-­‐4000  Hz).  You  can  do  this  quickly  by  

clicking  the  Speech  bubble  on  the  right.

   d. Increase  Voice  Detection  feature  in  the  Expert  Tuning>Situation  Management  

 e. Decrease  compression  ratio  (CR)  in  Details  (Gain  and  Compression)  

 f. Set  aid  to  linear  operation  (CR=1.0)  (Details  window)    g.  Change  fitting  formula  to  NAL-­‐NL2  

 3. Too  sharp  or  shrill  

a. Go  to  the  Fitting  Assistant  and  follow  detailed  instructions.  b. Decrease  gain  at  freqs  >  3  kHz  c. Go  to  Express  Tuning>Tonal  Perception.    Balance  is  like  a  teeter  totter.    The  “moon”  

increases  lows,  decreases  highs;  the  “sun”  increases  highs,  decreases  lows  

     

4. Too  loud  in  a  noisy  place  a. Go  to  the  Fitting  Assistant  and  follow  detailed  instructions.  b. Increase  Noise  Reduction.      

   c. Decrease  gain  for  high  input  levels.  

4    

   d. Decrease  max  output.    

   

e. Decrease  gain  in  the  low  frequencies.  5. “My  voice  sounds  strange.”  

a. Follow  detailed  instructions  in  the  Fitting  Assistant.  b. Test  for  occlusion  effect.  If  present,  enlarge  or  step  back  vent.  c. If  no  true  OE,  adjust  low-­‐freq  gain.    d. Adjust  the  freq  range  of  the  response  slope  (transition  from  low  to  high  frequencies).  e. Ensure  proper  fit  

6. Feedback    a. Make  sure  to  run  Critical  Gain  in  First  Fit  b. Set  Feedback  X  to  premium.

c. Decrease  HF  gain  d. Decrease  vent  diameter  e. Check  fit  of  aid  or  earmold.  f. Check  direction  of  receiver  outlet  relative  to  canal  bends.  If  it  is  too  close  to  the  canal  

wall,  shorten  canal  portion  of  the  aid  or  earmold.  7. Far  away  speech  better  to  understand  than  nearby  speech  

a. Decrease  gain  for  low  input  levels  b. Increase  gain  for  mid  and  high  input  levels  c.  Decrease  compression  ratio  

 8. Unrealistic  Expectaitons  

a.  Counseling  the  patient  as  well  as  the  patient’s  family  is  very  important.      b. A  useful  comparison  is  comparing  hearing  loss  to  vision  loss,  especially  macular  

degeneration.      9.  “I  can’t  hear  well  with  the  television.”  

a.  Encourage  use  of  the  miniMedia.    Program  a  memory  for  transmitter  to  stream  television.  

10. “I  am  hearing  too  much;  things  are  too  loud.”  a.  Reduce  output.    Go  to  the  Situation  Management  tab  and  adjust  MPO  b.  Raise  Compression  ratio  c. Increase  Sound  Impulse  Management  

11. Receivers  keep  breaking  down  on  X-­‐  minis  a.  Cerumen  management  and  counsel  patient  on  the  importance  of  clear  ears.  b. Proactively  changing  the  click  domes  and  the  miniReceiver  wax  guards.
