ABSTRACT:
A sound level monitor device has a microphone. A sound level measurement circuit is coupled to the microphone. The sound level measurement circuit takes sound signals monitored by the microphone and converts the sound signals to digital signals. A display is coupled to the sound level measurement circuit. The display will show the different measurement signal values. A single control button is coupled to the sound level measurement circuit. Pressing the control button a first time activates the sound level measurement circuit so a current measurement signal value is shown on the display. Pressing the single control button a second time causes a highest recorded measurement signal value, since the sound level measuring device has been presently activated, to be shown on the display. The highest recorded measurement signal value remains on the display until a higher recorded measurement signal is monitored. Pressing and holding the single control button for a predetermined time frame deactivates the sound level monitor device.
