An apparatus and method for preventing an acoustic shock of a portable terminal are disclosed. The apparatus includes a transceiver gain determining unit including a table of gain values for sound signals in each of one or more call modes, configured to output a particular gain value corresponding to a particular call mode; a reference value determining unit configured to receive the gain value from the transceiver gain determining unit, monitor a change in the gain value, and determine a predetermined reference energy value based on the change in the gain value; and an output level adjusting unit configured to receive an input signal, compare the input signal with the predetermined reference energy value, and adjust the level of the input signal to output an output signal.

Apparatus and method for preventing acoustic shock of portable terminal

A receiver suppresses noise simultaneously using a noise suppressor and an automatic gain controller (AGC). The receiver divides a received signal into an audio period and a non-audio period, analyzes whether the noise characteristic of the non-audio period corresponds to a non-static noise or a static noise, and if the noise characteristic corresponds to the static noise, analyzes whether the static noise is caused by a network or a transmitter side terminal. In accordance with the analyzed noise characteristic, the noise suppressor firstly suppresses the noise by determining the noise suppressing intensity, and sends a signal, from which the noise has been firstly suppressed, to the AGC. The AGC secondly suppresses the noise included in the signal. In this case, the threshold value of the AGC is controlled in real time in accordance with the noise characteristic. Also, since the noise level is lowered by the first noise suppressing, the threshold value of the AGC can be set to a lower value, and thus a swing phenomenon and a radiotelegraph phenomenon can be reduced.
