2. Features high sensitivity; in a confined environment, normal speech can be detected from a distance of up to 10 meters. 1. Utilizes an original, high-sensitivity microphone capsule paired with an LM2904 operational amplifier, offering the advantages of low power consumption and minimal total harmonic distortion. 3. Provides a direct linear analog output, greatly simplifying the process of Analog-to-Digital (AD) data acquisition and eliminating many of the difficulties typically associated with direct waveform sampling. It can also be utilized directly as a decibel sensor (though this requires conversion via software algorithms).
