AUDIO SYSTEM USING SOUND LEVEL METER

摘要

The present invention relates to an audio system using a sound level meter. The audio system allows a user to hear speaker sound without a dead zone of sound by installing the sound level meter at a dead zone of sound where the speaker sound can be hardly heard in operating the audio system and adjusting the volume so the volume of speaker output signal components inputted in the sound level meter may be appropriate for hearing. The system allows a lecturer to give a lecture without any risk factor of health such as vocal cord nodules, etc. through a visible representation of energy, volume or sound pressure of the speaker output signal components by uttering voice at an appropriate magnitude. The system allows the user to suppress howling phenomenon generated from excessively raised volume by adjusting the volume to a proper level for all audience members to clearly hear.
