When there is a match that sound is transmitted on to the other end of the line and person at the other end listen to the
spoken words.A needle containing two fine-wired electrodes is inserted through the skin into the muscle tissue. Normal
muscles at rest make certain, normal electrical sounds when the needle is inserted into them. A trained professional
(such as a neurologist, physiatrist, or physical therapist) observes the electrical activity while inserting the electrode.
The insertionalactivity provides valuable information about the state of the muscle and its innervating nerve. Then the
electrical activity when the muscle is at rest is observed. Each electrode track gives only a very local picture of the
activity of the whole muscle. Because skeletal muscles differ in the inner structure, the electrode has to be placed at
various locations to obtain an accurate signal. Thus by this way the speech can be communicated without sound.
