In view of the facts just stated, it will be seen that the remedy for "poor hearing," and poor memory of things heard is to be found in the use of the will in the direction of voluntary attention and interest. So true is this that some authorities go so far as to claim that many cases of supposed slight deafness are really but the result of lack of attention and concentration on the part of the person so troubled. Kay says: "What is commonly called deafness is not infrequently to be attributed to this cause--the sounds being heard but not being interpreted or recognized ... sounds may be distinctly heard when the attention is directed toward them, that in ordinary circumstances would be imperceptible; and people often fail to hear what is said to them because they are not paying attention." Harvey says: "That one-half of the deafness that exists is the result of inattention cannot be doubted." There are but few persons who have not had the experience of listening to some bore, whose words were distinctly heard but the meaning of which was entirely lost because of inattention and lack of interest. Kirkes sums the matter up in these words: "In hearing we must distinguish two different points--the audible sensation as it is developed without any intellectual interference, and the conception which we form in consequence of that sensation." The reason that many persons do not remember things that they have heard is simply because they have not _listened_ properly. Poor listening is far more common than one would suppose at first. A little self-examination will reveal to you the fact that you have fallen into the bad habit of inattention. One cannot listen to everything, of course--it would not be advisable. But one should acquire the habit of either really listening or else refusing to listen at all. The compromise of careless listening brings about deplorable results, and is really the reason why so many people "can't remember" what they have heard. It is all a matter of habit. Persons who have poor memories of ear-impressions should begin to "listen" in earnest. In order to reacquire their lost habit of proper listening, they must exercise voluntary attention and develop interest. The following suggestions may be useful in that direction.
