If u hold audible range aid would u hear clear approaching middle-of-the-road?
my mom wears one and she say that she hears better but it is nit one and the same as when she was younger. sometimes she hear high pitched noise. but she can hear well ample to live a normal time.
It depends on several things: what type of loss you have (conductive or sensorineural), the height of the loss (i.e. how many decibels -- since every 10 dB is 10x as loud, the difference between a 30 dB loss and a 60 dB loss is huge), and the frequency of the loss (low frequency, big frequency, all frequencies). It also depends VERY much on whether you are using analog or digital audible range aids. If you are using analog hearing aids, it is completely unlikely that your hearing will be as clear as it be before the loss. That is because analog aids amplify everything, including setting noise. Digital audible range aids are better at filtering out backgroud tumult and just amplifying speech. But merely like when your are listen to a radio which is cranked to the maximum volume, it is harder to understand the lyrics, the more "power" that have to be pumped through your aids (i.e. higher volume because of better decibel losses) the higher the break that there will be uncorrectable distortion. Most ancestors adapt to the change fairly like a shot, however.
