Abstract
A sound level indicator apparatus includes a signal processing element which detects and processes sound pressure waves into quantifiable electrical signals. The indicator also includes an adjustment member which adjusts the quantifiable signals to compensate for intrinsic electrical variations in the processing element. Further included is a monitoring member which detects when the received sound is below a predetermined level. The indicator still further includes an indicator element which displays the quantified quantifiable signals and the low level monitor detection signal. The sound level indicator is operatively combined with a digital watch integrated circuit for containment in a case which is wearable on one's wrist.
