Side Tone

Side Tone Points : Side Tone volume, headset, Telephony When we speak in front of the telephone transmitter, we hear our own voice in the receiver as a feedback. With the help of this feedback we are able to adjust the volume of our voice according to different situations. When the level of this feedback is high, we lower our voice and when it is low, we speak louder. This feedback voice is called side tone.

Side tone may be defined as the reproduction of sound in the receiver picked up from the associated transmitter. Or the amount of voice power coupled from the transmitter to the receiver of the same telephone.

Too much side tone and complete absence of it is undesirable. In the former case, the speaker will keep his level of volume of voice very low and hence will affect the output of the transmitter. In the latter case, the telephone will appear dead to the subscriber and this is a very uncomfortable feeling. The desirable amount of side tone is that which we have in our daily free air conversation with each other across the table.
