Systems and methods for tunable acoustic direction sensing are described herein. In one example, a system includes a first circuit and a second circuit capacitively coupled by a coupling capacitor, wherein the first circuit and the second circuit each comprise an inductor, a capacitor, and a resistor forming a frequency-selective network. A first acoustic transducer is coupled to the first circuit and a second acoustic transducer is coupled to the second circuit. At least one electrical element of the first circuit, the second circuit, or the coupling capacitor is a tunable electrical element configured to alter at least one of a resonance frequency, a bandwidth, or a damping characteristic of the first circuit or the second circuit. The first circuit and the second circuit generate respective output voltages that differ as a function of an incident angle of an acoustic wave, enabling determination of a direction of the acoustic wave.
