Abstract

Sound alarm and sound level limiting device.It includes an input stage with amplifier and attenuator of the signals generated by a microphone located in the area to be controlled and followed by weighting filters, an effective value and peak detector, and an analogue/digital converter whose output is applied to a microprocessor accompanied by a numeric indicator of the perceived values, an alarm device with light indication, an attenuator, and an activator. Applicable to the control of the sound level of an area.
