Abstract

A method and system to monitor and adjust sound waves. The system includes microphone unit, noise-cancellation circuitry, input audio source, processing unit, and microcontroller unit. The microphone unit detects ambient sound waves after turning on microphone unit. The noise-cancellation circuitry creates sound waves that are 180 degrees out of phase with the detected ambient sound waves to cancel ambient sound waves. The processing unit processes sound waves received from noise-cancellation circuitry and audio signals received from input audio source into output sound waves, and further measures quantified level of loudness of output sound waves. The microcontroller unit aggregates, and compares received quantified level of loudness of output sound waves with a pre-stored quantified value of sound waves. The processing unit adjusts output sound waves to pre-defined value of sound waves in case compared quantified level of loudness of output sound waves exceeds from the pre-stored quantified value of sound waves.
