What is claimed is:

1. A method for determining proper position of sensor pod on a patient comprising:

Performing a first diagnostic test on a sensor pod wherein said first diagnostic test is performed using an self-diagnostic test, comprising a base unit having a cradle for receiving said sensor pod, a speaker, a processing unit, a display, and at least one indicator; wherein while sensor pod is engaged in the base unit cradle and a predefined set of tones is played from the speaker and compared to the predefined set of tones for tolerance within 25% of the frequency of the predefined set of times; confirming proper function of each of the sensor pods within said 25% tolerance; placing said sensor pod onto a patient in a first position, wherein an active quality control procedure is

performed; detecting sounds from the patient and comparing the detected sounds, in real- time, with an expected sound signature, wherein appropriate position is indicated when the detected sound is within 25% of the frequency of the expected sound; and wherein the system provides a second indicator if said detected sound is not within 25% of the frequency of the expected sound.

2. The method of claim 1 further comprising moving the sensor pod to a second position if the sensor is not within 25% of the frequency of the expected sound.

3. The method of claim 1 wherein another audio or visual alarm or mechanism may be further included in the system so as to aid in the placement of the sensor pods on a patient.

4. The method of claim 2 wherein a set of indicators identifies whether the second position is closer to the 25% tolerance or farther away from said 25% tolerance from said first position. 5. The method of claim 1 wherein the tolerance is 10%.

6. A method of confirming the proper position of a medical device upon a patient comprising:

a. performing a first quality control procedure to ensure functioning of the sensor pods, comprising playing a predetermined set of sounds, detecting said predetermined set of sounds to create a first detected sounds, and comparing the predetermined sounds to the first detected sounds;

b. performing a second quality control procedure by detecting a second detected sounds from a patient wherein the second quality control procedure compares the second detected sounds to a predetermined sound signature corresponding to the particular artery or vessel of interest; and

c. triggering an alarm wherein the second detected sound does not meet the

predetermined sound signature, or triggering an approval if the second detected sound is within a predefined tolerance from the predetermined sound signature. 7. The method of claim 6, wherein the tolerance is 25%.

8. The method of claim 6 wherein in step a, the comparison requires a tolerance of 25% to move to step b.

9. A base unit for performing a self-diagnostic quality control process on at least one sensing pod; said base unit comprises a computer implemented software connected to a database system, charging units, and a speaker, wherein the software plays a predetermined set of tones through the speaker and wherein a sensor pod placed within said base unit detects and displays the detected sound, which is compared to the predetermined set of tones played by the speaker; wherein replacement of a sensor pod is determined after the lesser of 50 quality control runs, or two quality control runs wherein the sensor pod diverges from the predicted sound by greater than 10%.

10. A method of determining replacement of a wear unit comprising performing a quality control test of at least one sensor pod, comprising, placing said sensor pod onto a base unit, wherein said base unit comprises a computer implemented software connected to a database system, charging units, and a speaker, wherein the software plays a

predetermined set of tones through the speaker and wherein a sensor pod placed within said base unit detects and displays the detected sound onto a display, which is compared to the predetermined set of tones played by the speaker; and determining whether to replace said sensor pod, wherein replacement of a sensor pod is determined after the lesser of 50 quality control runs, or two quality control runs wherein the sensor pod diverges from the predicted sound by greater than 10%.

11. A method for performing a quality control procedure on a listening device comprising: a listening device having at least one sensing element, and a base, said base comprising at least one speaker and a processing unit capable of playing a pre-determined set of tones through said speaker; playing a pre-determined set of tones through said speaker;

detecting said pre-determined tones in said at least one sensing element; comparing the pre-determined tones to the detected tones; providing an indicator that the pre-determined tones are within a pre-determined tolerance of the detected tones and indicating an approval if the detected tones are within said tolerance and a rejection of the detected tones are outside of said tolerance; placing said sensing element on a patient adjacent to the carotid artery; detecting sounds from the carotid artery; comparing the sounds from the carotid artery to a predetermined carotid sound; providing a notification that the detected sounds from the carotid artery are within a pre-determined tolerance, or a rejection if the detected sounds are outside of the pre-determined tolerance; where the detected sounds are within the pre-determined tolerance, detecting sounds from the carotid artery and saving into storage for processing said sounds.

12. The method of claim 11, wherein the indicator is selected from a tone, light, visual, or audio indication.

13. The method of claim 11, wherein the notification is selected from a tone, light, visual, or audio notification.

14. The method of claim 11, wherein the indicator is provided on the base unit.

15. The method of claim 11, wherein the notification is provided on the sensor pod.

16. The method of claim 11, wherein the indicator and the notification are the same.

17. The method of claim 11, wherein a further step comprises replacing said sensing element if a rejection is provided, and restarting the quality control procedure.
