• selectable electronic components at least one of which varies the sound response characteristics of sound passing through the test module with the selection of components being made by the operator's console such that the patient is presented with a pair of different sound response characteristics as a paired comparison;
• at least two light panels each of which is alternatively activated for each of the paired comparison sound response characteristics;
• selection means for responding to one of the paired comparison sound response characteristics or light panels;
• separate volume controls to change the volume of sound passing through the left and right test modules;
• wherein both the patient console and the operator's console comprise means for transmitting the receiving data from and to the other console;
• and
• wherein the operator's console further comprises means for selecting the electronic components in the patient console such that the selections of electronic components are presented as a series of paired comparisons to the patient for a patient preferred selection of each of the paired comparisons.

A method of providing a patient selectable hearing aid during a single visit to a dispenser's office comprising:

• establishing a first sound signal simulating a background acoustical environment;
• establishing a second sound signal for testing purposes;
• mixing the first and second sound signals and presenting them to a hearing impaired patient;
• selecting one of a plurality of earshell assemblies, the selected earshell assembly conforming to the size and geometry of the patient's hearing impaired ear;
• selecting one of a plurality of venting conditions for the earshell assembly;
• inserting a test module in the selected earshell assembly for modifying sound response characteristics of the established sound signals;
• varying at least one of the sound response characteristics of the test module such that the patient is presented with a pair of different sound response characteristics as a paired comparison of two members;
• choosing by patient selection which member of the paired comparison of sound response characteristics best aids the patient's hearing impediment;
• and
• providing to the patient during the same office visit that the testing takes place a prefabricated hearing aid having the same sound response characteristics as chosen by the patient to best aid the hearing impediment.

A test device for prescribing the electronic sound response characteristics of hearing aid for a patient with an impaired hearing condition comprising:

• at least one test signal sound source for creating a sound to be listened to by the patient through electronic components to select preferred sound response characteristics of the sound as passed through the electronic components;
• an operator test console for selectively determining the sound response characteristics to be presented to the patient through the electronic components;
• means for presenting each of a set of pairs of different sound response characteristics as a paired comparison to the patient;
• a test module for insertion into the patient's ear for receiving each of the paired comparisons so that the patient may choose which one of each paired comparison best assists the patient's hearing condition;
• means for demarking the listening interval of each of the pair of different sound response characteristics;
• and
• means for permitting the patient to select one of each paired comparison.

A test device for prescribing the electronic sound resonse characteristics of a hearing aid for a patient with an impaired hearing condition comprising:

• electronic circuit means for selectively creating varying sound response characteristics and presenting the sound response characteristics to the patient in paired comparisons;
• means inserted into the patient's ear for receiving the paired comparisons of sound response characteristics so that the patient may choose which sound response characteristic best assist the patient's hearing condition;
• and
• means for enabling the patient to select which sound response characteristic best assists the patient's impaired hearing condition.

A test device for prescribing a hearing aid for a patient with an impaired hearing condition comprising:

• an earshell assembly for insertion into the patient's ear;
• a test module comprising a microphone and receiver contained within the earshell assembly;
• variable amplifying means connected to the test module for varying amplified sound response characteristics of the sound and for presenting the amplified sound response characteristic in paired comparisons so that the patient can select which amplified sound response characteristic best assists the patient's impaired hearing condition;
• and
• means to indicate to the patient when each of the pair of sound response characteristics are being presented.

A patient controlled master hearing aid comprising:

• a sound receiver for insertion into the patient's ear;
• a patient console connected to the receiver comprising at least one volume control to vary the volume of sound passing through the receiver;
• an operator's console connected to the patient console comprising:
• at least one means for monitoring the volume of sound chosen by the patient on the patient console volume control;
• and
• means for varying the volume selected by the patient whereby the operator can override the selection of volume control chosen by the patient and independently control the volume of sound transmitted through the receiver.

A method for prescribing the electronic sound response characteristics of a hearing aid for a patient with an impaired hearing condition comprising:

• creating a sound to be listened to by the patient through electronic components;
• selectively determining the sound response characteristics to be presented to the patient through the electronic components and presenting each of a set of pairs of different sound response characteristics of the patient as paired comparisons;
• presenting each paired comparison to the patient so that the patient may choose which one of each paired comparison best assists the patient's hearing condition;
• and
• demarking each sound response characteristic interval in each set of pairs of different sound characteristics so that the patient can select one of each paired comparison.

A method for prescribing the electronic sound response characteristics of a hearing aid for patient with an impaired hearing condition comprising:

• inserting a receiver into the patient's ear so that the patient may choose which sound response characteristics of sound transmitted to the receiver best assists the patient's impaired hearing condition;
• selectively presenting varying sound response characteristics to the patient by presenting each of a set of pairs of different sound response characteristics as paired comparisons the variations being caused by switching between different electrical components;
• and
