이와 같이, 종래 이동 통신 단말기는 사용자에 의해 선택된 음량 레벨로 고정되므로 주위 환경에 상관없이 미리 설정된 음량 레벨로만 통화가 가능하다. 그러므로, 종래 이동 통신 단말기는 사용자가 아주 시끄러운 곳에서 기설정된 수신 음량이 너무 작아서 통화가 불가능한 경우 수신 음량을 재설정해야 하는 번거로움이 있다. 또한, 종래 이동 통신 단말기는 사용자가 아주 조용한 곳에서 통화를 하더라도 기설정된 수신 음량이 너무 커서 주위 사람들에게 방해를 주는 경우 통화중에 음량 레벨을 재설정해야하는 번거로움이 있다. 이처럼 종래 이동 통신 단말기는 외부 잡음이 클 때 사용자가 느끼는 신호대 잡음비가 작아서 통화시 상대방의 목소리가 제대로 안들리는 경우가 발생하고, 통화 당사자의 송신음량이 커져서 상대방에게 너무 큰 음량이 전달되는 문제점이 발생한다.As described above, since the conventional mobile communication terminal is fixed at the volume level selected by the user, the call can be made only at the preset volume level regardless of the surrounding environment. Therefore, the conventional mobile communication terminal has a hassle that the user has to reset the received volume when the call is impossible because the preset received volume is too small in a very noisy place. In addition, the conventional mobile communication terminal has a hassle of having to reset the volume level during a call even if the user makes a call in a very quiet place if the preset received volume is too large to disturb people around. As such, the conventional mobile communication terminal has a small signal-to-noise ratio that the user feels when the external noise is too large, so that the voice of the other party cannot be heard properly. do.
